In this paper, we analyze the security of two zero-knowledge identification schemes based on cornbinatorial NP-cornplete problems, PKP (Shamir [3]) and CLE (Stem [5]). We use two different approaches in order to determine, on the one hand, the theoretical limit to the efficiency of the known attacks

โฆ Synopsis
We present in this paper an idea ofhow to reduce the number of possible permutations when trying to solve the permuted kernels problem. We refer to the identification scheme of Shamir [2] and we also show how a dishonest prover can maximize his prospects to pass the test.

## In 2001, Harn and Lin [4] proposed a non-repudiation metering scheme. In this paper, we reveal two security weaknesses in their scheme, which could make the scheme either too inefficient or incapable of presenting the exact visiting number of a server. An improved scheme will be presented in th
In a multi-proxy signature scheme, an original signer could authorize a proxy group as his proxy agent. Then only the cooperation of all the signers in the proxy group can generate the proxy signatures on behalf of the original signer. Recently, Cao and Cao gave the first formal definition and secur
## Abstract In this paper, a simple image secure communication scheme based on the chaotic Chebyshev map and chaos synchronization is proposed. The scheme relies on the excellent correlation property of chaotic sequences, which is very desirable for secure image communication. The results obtained
