Tensor-Based Trapdoors for CVP and Their Application to Public Key Cryptography
We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product. Using these trapdoors we set up a lattice-based cryptosystem which ...

Generic Transformation to Strongly Unforgeable Signatures
Recently, there are several generic transformation techniques proposed for converting unforgeable signature schemes (the message in the forgery has not been signed yet) into strong...

On Cryptographic Assumptions and Challenges
We deal with computational assumptions needed in order to design secure cryptographic schemes. We suggest a classi£cation of such assumptions based on the complexity of falsifying...

A New Rabin-type Trapdoor Permutation Equivalent to Factoring
Public key cryptography has been invented to overcome some key management problems in open networks. Although nearly all aspects of public key cryptography rely on the existence of...

Security Flaws in Several Group Signatures Proposed by Popescu
In resent years, Popescu proposed several group signature schemes based on the Okamoto-Shiraishi assumption in [8–11], and claimed his schemes are secure. However, this paper dem...
