On the Fly Authentication and Signature Schemes Based on Groups of Unknown Order
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...

Private Computation: k-Connected versus 1-Connected Networks
We study the role of connectivity of communication networks in private computations under information theoretic settings. It will be shown that some functions can be computed by pr...

Elliptic Curves with Low Embedding Degree
Motivated by the needs of the pairing based cryptography, Miyaji, Nakabayashi and Takano have suggested a construction of so-called MNT elliptic curves with low embedding degree. ...

An Improved Real-Quadratic-Field-Based Key Exchange Procedure
To date, the only non-group structure that has been suitably employed as the key space for Diffie-Hellman type cryptographic key exchange is the infrastructure of a real quadratic ...

An Extension of Kedlaya's Algorithm to Hyperelliptic Curves in Characteristic 2
We present an algorithm to compute the zeta function of an arbitrary hyperelliptic curve over a finite field Fq of characteristic 2, thereby extending the algorithm of Kedlaya for ...
