A Blind Digital Signature Scheme Based on Hyperelliptic Curve Cryptosystem
Yanqin Zhu · Microelectronics & Computer · 2007
The hyperelliptic curve cryptosystem is based on the hyperelliptic curve discrete logarithm problem, and has the higher safety and the shorter operands compared to other cryptosystems. In this paper, we propose a blind signature scheme based on the hyperelliptic curve cryptosystem. The legal user blinds the signed message by the random number, and it is difficult for illegal users to analyze the plaintext without blind factor. This scheme can prevent the illegal user from forging and juggling the message, and has the higher safety.
