Non-interactive Deniable Authentication Protocols,a key-compromise-impersonation attack. We analyze some NIDA protocols in the model, and we find that no one is satisfactory. We give a new paradigm to construct an NIDA protocol, which is provably secure in the model.

On the Probability Distribution of the Carry Cells of Stream Ciphers F-FCSR-H v2 and F-FCSR-H v3,loiting the bias in the carry cells of a Galois FCSR. In order to resist this attack, at SAC 2009 F. Arnault . proposed the new stream cipher F-FCSR-H v3 based upon a ring FCSR. M. Hell and T. Johansson only presented experimental results but no theoretical results for the success probability of the

Efficient Self-certified Signatures with Batch Verification,e concept of . public key was put forth by Girault. In this paper, we propose an efficient and novel self-certified signature scheme, which requires only one modular multiplication in signing with pre-computation. One of features of our scheme lies in its batch verification in both single-signer and

Weak-Key Class of MISTY1 for Related-Key Differential Attack,e algorithm, a weak-key class encompassing 2. weak keys of MISTY1 is found. Then we present 7-round related-key differential characteristics of MISTY1 under the weak-key class, which lead to the attacks on the 8-round MISTY1 without the first . lay. The attack requires 2. chosen ciphertexts, and the

Cryptanalysis of Reduced-Round KLEIN Block Cipher,st investigate the security of KLEIN against truncated differential analysis. We construct a 6-round truncated differential distinguisher based on a careful observation about the characteristic of KLEIN round function. With the help of this new distinguisher, we give a truncated differential analysi

An Efficient RSA Implementation without Precomputation,putation. Precomputation improves the speed and in the meanwhile makes the algorithms more complex. The complex algorithms are not suitable for hardware implementation. We propose a new algorithm without precomputation, which is more efficient even compared with the ones with precomputation. Our alg
