We present an algorithm for counting points on superelliptic curves yr = f(x) over a finite field Fq of small characteristic different from r. This is an extension of an algorit...
Abstract. At Crypto ’88, Matsumoto, Kato and Imai proposed a protocol, known as RSA-S1, in which a smart card computes an RSA signature, with the help of an untrusted powerful se...
The Advanced Encryption Standard (AES) provides three levels of security: 128, 192, and 256 bits. Given a desired level of security for the AES, this paper discusses matching publi...
Attacks are presented on the IBM 4758 CCA and the Visa Security Module. Two new attack principles are demonstrated. Related key attacks use known or chosen differences between two...
Abstract. This work proposes a new elliptic curve processor architecture for the computation of point multiplication for curves defined over fields GF(p). This is a scalable arch...
