摘要: 
Blind signature is an important technique of modern cryptography. Recently, Mohammed et al. proposed a blind signature scheme based on ElGamal signature. This paper shows that the proposed blind signature is not secure. The requester will obtain the secret key of the signer from a valid blind signature. Thus, the requester may forge any valid signature for any message.

盲簽章是近代密碼學的一種重要技術,近年來Mohammed等人提出一種植基於ElGamal模式的盲簽章,本文將證明這種盲簽章方式是不安全的,要求簽章者將從簽章者的有效盲簽章中獲得簽章者之密鑰。因此,要求簽章者可以對任何訊息偽造有效的簽章。
