  • TBMP | Privacy-Preserving Public Auditing for Data Storage Security in Cloud Computing info@ To know more : Abstract Cloud Computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. By data outsourcing, users can be relieved from the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the possibly large size of outsourced data makes the data integrity protection in Cloud Computing a very challenging and potentially formidable task, especially for users with constrained computing resources and capabilities. Thus, enabling public auditability for cloud data storage security is of critical importance so that users can resort to an external audit party to check the integrity of outsourced data when needed. To securely introduce an effective third party auditor (TPA), the following two fundamental requirements have to be met: 1) TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data, and introduce no additional on-line burden to the cloud user; 2) The third party auditing process should bring in no new vulnerabilities towards user data privacy. In this paper, we utilize the public key based homomorphic authenticator and uniquely integrate it with random mask technique to achieve a privacy-preserving ...
  • Blinding Curiosity: Supporting User Preferences and Privacy Within Workplace Awareness Applicastions Google Tech Talk (more below) November 2, 2010 Presented by Eleanor Rieffel and Jacob Biehl, FXPal Labs. ABSTRACT Awareness systems are an emerging class of technologies that enhance communication and connections between people in both business and social settings. MyUnity, a prototype awareness platform designed and developed at FXPAL for use in the workplace collects a myriad of data from a variety of sensors and sources, fuses the data into descriptive, easy to understand presence states, and presents this information to users in a novel interface available to users on their desktops, laptops, and mobile devices. The platform has been in continuous use within FXPAL for more than a year. Important to MyUnity's adoption is its ability to allow users to control how data about them is collected and stored. To avoid concerns about misuse, initially the system did not store any data. Researchers developing the system were interested, however, in ***yzing usage patterns, and users expressed interest in seeing personal trends, activity patterns of coworkers, and long-term data pooled across groups of users, all requiring data to be stored. At the same time, users continued to be concerned about misuse of stored data. In this talk, we highlight our approach to providing varying levels of access to historical data while respecting user concerns about stored data. We developed a security mechanism that enables MyUnity to provide "need to know" security in which each individual ...
  • Cryptography Research Cryptography Research IBM and the Future of Cyber Security By 2011, the world will be 10 times more instrumented than it was in 2006. Internet connected devices will leap from 500 Million to 1 Trillion. Approximately 70% of the digital universe is created by individuals, but enterprises are responsible for 85% of the security, privacy, reliability, and compliance. Increasingly, the proliferation of data-generating sensors and mobile computing devices, and the emergence of new forms of communication such as social networking, are driving unprecedented growth in the collection, storage and management of all types of data. Not surprisingly, this phenomenon has sparked growing demand for the ability to extract intelligence from these massive mountains of information—intelligence that can enable organizations to improve their decision-making and run their businesses more effectively and efficiently. With this capacity to rapidly sift thru data and gain new insights comes a significant challenge and responsibility when it comes to personal information, or information that relates to identifiable individuals: how to enable the exchange and ***ysis of data, while protecting privacy. IBM has long recognized the importance of information privacy and led by example in its own privacy polices and practices: the company was the first multinational to adopt a global privacy policy in the late 1960s, and continued that leadership as recently as 2005 when it was the first company to ...

  • Cooperative Provable Data Possession for Integrity Verification in Multi Cloud Storage Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distribu ted cloud storage to support the scalability of service and data migration,in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients' data. We present a cooperative PDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy. We prove the security of our scheme based on multi-prover zero-knowledge proof system, which can satisfy completeness, knowledge soundness, and zero-knowledge properties. In addition, we articulate performance optimization mechanisms for our scheme, and in particular present an efficient method for selecting optimal parameter values to minimize the computation costs of clients and storage service providers. Our experiments show that our solution introduces lower computation and communication overheads in comparison with non-cooperative approaches.
  • Wikileaks has launched its own social network called Friends of Wikileaks (or WL Friends for short) as the whistleblowing website claims that Facebook sells users' information to governments and cannot be trusted. Read more: WL Friends is a social network aimed at bringing like-minded people together who do not yet know each other, in contrast to Facebook, which is mostly about contact with friends that you already have - something that Wikileaks claims is pointless. The website says "Friends of WikiLeaks is a network of people from across the globe who defend WikiLeaks, its people, its alleged sources and its mission. We publicly and privately promote WikiLeaks and individuals and organisations aligned with the mission of WikiLeaks. "This site will help you to join with people like you in your area and across the world. You will make new friends and new allies, care for treasured values and fight in common cause." Before launching the social network on 20 May, Wikileaks listed a number of reasons stating why it claims WL Friends is better than Facebook - which floated two days previous for $104bn (£62bn). "WL Friends introduces you to people you want to know, but don't know yet. Facebook connects you to people you already know - no point," the site said on Twitter, adding: "Facebook is a mass surveillance tool. You put friends into it, you betray your friends. Do friends betray friends?" Signing up to WL Friends requires an email address and password, but ...
  • Vector differentials Part 1B In previous videos we established differentials as elements of the epsilon neighborhood of zero. Further, we found a multiplicative semi-group algebra on the dx's, and finally established a closed additive algebra of differentials that is homomorphic to addition on the real numbers. These results open up a flood of new applications for differentials. Here we develop Linear Spaces of differentials that are companions to corresponding Linear Spaces over the reals. They are linear spaces of vector differentials. BTW be sure to turn on annotations, they contain good stuff and necessary corrections.

  • Ensuring Data Storage Security in Cloud Computing Cloud computing has been envisioned as the next-generation architecture of IT enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy.

In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible distributed scheme with two salient features, opposing to its predecessors. By utilizing the homomorphic token with distributed verification of erasure-coded data, our scheme achieves the integration of storage correctness insurance and data error localization, ie, the identification of misbehaving server (s).

  • Network Coding Based Privacy Preservation against Traffic ***ysis in Multi-Hop Wireless Networks info@ Abstract Privacy threat is one of the critical issues in multihop wireless networks, where attacks such as traffic ***ysis and flow tracing can be easily launched by a malicious adversary due to the open wireless medium. Network coding has the potential to thwart these attacks since the coding/mixing operation is encouraged at intermediate nodes. However, the simple deployment of network coding cannot achieve the goal once enough packets are collected by the adversaries. On the other hand, the coding/mixing nature precludes the feasibility of employing the existing privacy-preserving techniques, such as Onion Routing. In this paper, we propose a novel network coding based privacy-preserving scheme against traffic ***ysis in multihop wireless networks. With homomorphic encryption, the proposed scheme offers two significant privacy-preserving features, packet flow untraceability and message content confidentiality, for efficiently thwarting the traffic ***ysis attacks. Moreover, the proposed scheme keeps the random coding feature. Theoretical ***ysis and simulative evaluation demonstrate the validity and efficiency of the proposed scheme.

  • Memory Delegation (Crypto 2011) Kai-Min Chung, Yael Kalai, Feng-Hao Liu, and Ran Raz Cornell University; Microsoft Research; Brown University; and Weizmann Institute of Science Abstract: We consider the problem of delegating computation, where the delegator doesn't even know the input to the function being delegated, and runs in time significantly smaller than the input length. For example, consider the setting of memory delegation, where a delegator wishes to delegate her entire memory to the cloud. The delegator may want the cloud to compute functions on this memory, and prove that the functions were computed correctly. As another example, consider the setting of streaming delegation, where a stream of data goes by, and a delegator, who cannot store this data, delegates this task to the cloud. Later the delegator may ask the cloud to compute statistics on this streaming data, and prove the correctness of the computation. We note that in both settings the delegator must keep a (short) certificate of the data being delegated, in order to later verify the correctness of the computations. Moreover, in the streaming setting, this certificate should be computed in a streaming manner. We construct both memory and streaming delegation schemes. We present non-interactive constructions based on the (standard) delegation scheme of Goldwasswer et. al. (STOC '08). These schemes allow the delegation of any function computable by an ${\cal L}$-uniform circuit of low depth (the complexity of the delegator depends ...

  • Dr Elham Kashefi: Quantum Turing test A fundamental goal in quantum information processing is to test a machine's (or more generally nature's) ability to exhibit quantum behaviour. The most celebrated result in this domain, which has been also demonstrated experimentally, is the celebrated Bell Theorem that verifies the non-local nature of quantum mechanics. Could we generalise such approaches to verify that a given device is in fact taking advantage of quantum mechanics rather than being a disguised classical machine? Considering the exponential regime of quantum mechanics, the issue of the efficiency of such tests is the key challenge from the complexity point of view. On the other hand, from the foundational point of view, it is an intriguing open question whether a fully classical scheme could verify any quantum properties of a larger system while being experimentally feasible. Kashefi presents some recent progress towards this direction that also has surprising consequences on an entirely different open question, the existence of fully homomorphic encryption schemes. Presented by Dr Elham Kashefi, School of Informatics, the University of Edinburgh. Recorded on Friday 11 May 2012 at the Informatics Forum, The University of Edinburgh. The Turing Research Symposium was organised by the Royal Society of Edinburgh and the University of Edinburgh School of Informatics in partnership with SICSA and supported by Cambridge University Press.

  • ctf game In capture the flag the defender can take back control at any time. The adversary only knows the state of the game when he moves. The secret's like the frequency can be chosen by a single person who does not need to be a developer. The responsible manager can encrypt his decision in a configuration file which is to be read at compile time before code obfuscation. One can inject this encrypted value without revealing the values to the developer that invokes the llvm and compilation process. For this advanced compilation technique the bank has to develop a separate injector based on pgp decryption. If the injector is using homomorphic techniques the values can also be determined after two or three different manager decide what value should be used in the end product. Homomorphic encrypted values can be used without decryption. This method could provide totally secret values that can reconstructed if and only if each manager provides his part of the input. So each manager can provide the number without either of them being able to find the value of the individual numbers. Since the injector never decrypts its input, it can be run by an untrusted party without revealing its inputs and internal state. The existence of a fully homomorphic injector would have great practical implications in the outsourcing of private software components. The ability to keep secrets is important for the future. The strategy needs to able to adapt in scenarios where information has leaked. It case ...
  • David Freeman: Homomorphic Signatures: Message Integrity for Network Coding and Beyond David Freeman: Homomorphic Signatures: Message Integrity for Network Coding and Beyond Network coding is a routing mechanism that offers increased throughput and improved robustness to random faults in completely decentralized networks. In contrast to traditional routing schemes, however, network coding requires intermediate nodes to modify data packets en route; for this reason, standard signature schemes are unable to ensure message integrity, and it is a challenge to provide resilience to tampering by malicious nodes. In this talk we will survey cryptographic methods for ensuring integrity in network coding. We will discuss three different methods, whose security depends on the difficulty of (variants of) of three different computational problems, respectively: computing discrete logarithms, factoring large integers, and finding short vectors in lattices. These schemes are examples of "homomorphic signatures," which are schemes that can authenticate computations on signed data. We will conclude with a more general example of homomorphic signatures. This talk will cover joint research with Dan Boneh, Jon Katz, and Brent Waters.
