On the Security of Multiple Encryption or CCA-security+CCA-security=CCA-security?
In a practical system, a message is often encrypted more than once by different encryptions, here called multiple encryption, to enhance its security. Additionally, new features ...

A Nonuniform Algorithm for the Hidden Number Problem in Subgroups
Boneh and Venkatesan have proposed a polynomial time algorithm in a non-uniform model for recovering a ”hidden” element α ∈ IFp, where p is prime, from very short strings of...

Undeniable Signatures Based on Characters: How to Sign with One Bit
We present a new undeniable signature scheme which is based on the computation of characters. Our signature scheme offers the advantage of having an arbitrarily short signature. I...

Constructing Committed Signatures from Strong-RSA Assumption in the Standard Complexity Model
Abstract. In this paper, we provide the first committed signature provably secure in the standard complexity model based on the strong RSA assumption. The idea behind the construc...

An RSA Family of Trap-Door Permutations with a Common Domain and Its Applications
Abstract. Bellare, Boldyreva, Desai, and Pointcheval [1] recently proposed a new security requirement of the encryption schemes called “keyprivacy.” It asks that the encryption...

Identity-Based Threshold Decryption
Abstract. In this paper, we examine issues related to the construction of identity-based threshold decryption schemes and argue that it is important in practice to design an identi...
