Abstract--In the bounded-storage model (BSM) for information-theoretic secure encryption and key agreement, one makes use of a random string R whose length t is greater than the as...
Public key cryptography is widely used to secure transactions over the Internet. However, advances in quantum computers threaten to undermine the security assumptions upon which c...
For most basic cryptographic tasks, such as public key encryption, digital signatures, authentication, key exchange, and many other more sophisticated tasks, ideal functionalities...
Most public key cryptosystems have been constructed based on abelian groups up to now. We propose a new public key cryptosystem built on finite non abelian groups in this paper. I...

Abstract. Recently, the Csignature scheme has been completely broken by Dubois et al. [2, 3]. As a consequence, the security of SFLASH and other multivariate public key systems hav...
