On the Security of 1024-bit RSA and 160-bit Elliptic Curve Cryptography
FREE DOWNLOAD
JW Bos, ME Kaihara, T Kleinjung - 2009 ,lacal.epfl.ch ABSTRACT. Meeting the requirements of NIST s new cryptographic standards means phasing out usage of 1024-bit RSA and 160-bit elliptic curve cryptography (ECC) by the end of the year 2010. This write-up comments on the vulnerability of these systems to an open

Cryptography based on error correcting codes
FREE DOWNLOAD
ABSTRACT. The idea to use error-correcting codes in order to construct public key cryptosystems was published in 1978 by McEliece [ME1978]. In his original construction, McEliece used Goppa codes, but various later publications suggested the use of different

A visual cryptography based watermark technology for individual and group images

ABSTRACT Radio Frequency IDentification (RFID) is emerging in a variety of applications as an important technology for identifying and tracking goods and assets. The spread of RFID technology, however, also gives rise to significant user privacy and security issues. One

Securing peer-to-peer mobile communications using public key cryptography: New security strategy
FREE DOWNLOAD
Mobile phones are considered to be the most common communication devices in history. Recently, mobile phones are not only used for casual greetings but also, sending and receiving important data such as, social security numbers, bank account details and

Cryptography based on bilinear maps
FREE DOWNLOAD
The bilinear mapping technique that uses the (Weil and Tate) pairings over elliptic (or hyperelliptic) curves represents a great breakthrough in cryptography. This paper surveys this new trend in cryptography, and emphasizes the design of efficient cryptographic

On white-box cryptography

ABSTRACT. White-box cryptography techniques are aimed at protecting software implementations of cryptographic algorithms against key recovery. They are primarily used in DRM-like applications as a cost-effective alternative to token-based protections. This

Evaluating large degree isogenies and applications to pairing based cryptography
FREE DOWNLOAD
We present a new method to evaluate large degree isogenies between elliptic curves over finite fields. Previous approaches all have exponential running time in the logarithm of the degree. If the endomorphism ring of the elliptic curve is small we can do much better, and

Skew Frobenius Map and Efficient Scalar Multiplication for Pairing–based Cryptography
FREE DOWNLOAD allbooks.org.ua This paper considers a new skew Frobenius endomorphism with pairing–friendly elliptic curve E (\ mathbbFp) E (F p) defined over prime field\ mathbbFp F p. Then, using the new skew Frobenius map, an efficient scalar multiplication method for pairing–friendly elliptic

Optimization of Public Key Cryptography (RSA and ECC) for 16-bits Devices based on 6LoWPAN

ABSTRACT Internet of things (IoT) is one of the last advances in ICT, providing a global connectivity and management of sensors, devices, users and information. Specifically, we are working on Future Internet devices based on 6LoWPAN. 6LoWPAN presents an

Lightweight cryptography for low cost RFID

Security and privacy concerns as well as the need for security services to enable the development of novel applications using low cost RFID have been illustrated in previous Chapters, and in particular various proposals made to address issues regarding

Dynamic key cryptography and applications
FREE DOWNLOAD dq99.net ABSTRACT In modern security models, cryptography plays a fundamental role in protecting data integrity and confidentiality in information systems. However, cryptography itself is subject to cryptanalysis attacks. To reduce the cryptanalysis attack risk, a dynamic key

Elliptic curve cryptography based threshold cryptography (ecc-tc) implementation for manets

Summary A Mobile Ad hoc Network (MANET) consists of multiple wireless mobile devices that form a network on the fly to allow communication with each other without any infrastructure. Due to its nature, providing security in this network is challenging.

Privacy-enhancing auctions using rational cryptography
FREE DOWNLOAD
We consider enhancing with privacy concerns a large class of auctions, which include sealed-bid single-item auctions but also general multi-item multi-winner auctions, our assumption being that bidders primarily care about monetary payoff and secondarily worry

On optimal heuristic randomized semidecision procedures, with applications to proof complexity and cryptography
FREE DOWNLOAD ras.ru ABSTRACT The existence of an optimal propositional proof system is a major open question in proof complexity; many people conjecture that such systems do not exist. Krajcek and

Introduction to Cryptography

Robust cryptography in the noisy-quantum-storage model
FREE DOWNLOAD cwi.nl It was shown in [42] that cryptographic primitives can be implemented based on the assumption that quantum storage of qubits is noisy. In this work we analyze a protocol for the universal task of oblivious transfer that can be implemented using quantumkey-distribution

Threshold cryptography based on Asmuth-Bloom secret sharing
