An Identification Scheme Based on Sparse Polynomials
This paper gives a new example of exploiting the idea of using polynomials with restricted coefficients over finite fields and rings to construct reliable cryptosystems and identif...

Efficient and Secure Comparison for On-Line Auctions
In this note, we describe a correction to the cryptosystem proposed in [1, 2]. Although the correction is small and does not affect the performance of the protocols from [1, 2], it...

Strengthening McEliece Cryptosystem
McEliece cryptosystem is a public-key cryptosystem based on error-correcting codes. It constitutes one of the few alternatives to cryptosystems relying on number theory. We present...

On the Security of Cryptosystems with All-or-Nothing Transform
We study the data privacy of cryptosystems with All-or-Nothing transform (AONT). An AONT is an efficient computable transform with two properties: Given all the bits of its output...

Cryptanalysis of HFEv and Internal Perturbation of HFE
Hidden field equation (HFE) multivariable cryptosystems were first suggested by Patarin. Kipnis and Shamir showed that to make the cryptosystem secure, a special parameter D of a...

Weak Key Analysis and Micro-controller Implementation of CA Stream Ciphers
Abstract. In the paper we extend known results studying the application of CAs for stream ciphers. We illustrate the notion of weak keys in such a cryptosystem and describe the exp...

Multi-bit Cryptosystems Based on Lattice Problems
Abstract. We propose multi-bit versions of several single-bit cryptosystems based on lattice problems, the error-free version of the Ajtai-Dwork cryptosystem by Goldreich, Goldwass...
