In this paper we present a new practical key-recovery attack on the SFLASH signature scheme. SFLASH is a derivative of the older C∗ encryption and signature scheme that was broke...

We present a somewhat homomorphic encryption scheme that is both very simple to describe and analyze, and whose security (quantumly) reduces to the worst-case hardness of problems ...

We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an...

Abstract. Proofs of security protocols typically employ simple abstractions of cryptographic operations, so that large parts of such proofs pendent of cryptographic details. The ty...
