We present a generic transformation that allows us to use a large class of pairing-based signatures to construct schemes for signing group elements in a structure preserving way. A...

We propose a new homomorphic encryption scheme based on the hardness of decoding under independent random noise from certain affine families of codes. Unlike in previous latticeba...

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 new candidates for quantum-resistant public-key cryptosystems based on the conjectured difficulty of finding isogenies between supersingular elliptic curves. The main t...
