Abstract. We present new results in the framework of secure multiparty computation based on homomorphic threshold cryptosystems. We introduce the conditional gate as a special type...
A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple c...
Attacks are presented on the IBM 4758 CCA and the Visa Security Module. Two new attack principles are demonstrated. Related key attacks use known or chosen differences between two...
In this paper we show how to convert a statistically binding but computationally concealing quantum bit commitment scheme into a computationally binding but statistically concealin...
We propose a threshold RSA scheme which is as efficient as the fastest previous threshold RSA scheme (by Shoup), but where two assumptions needed in Shoup’s and in previous schem...
