Abstract :
Two attacks are given to show that the identity-based signature scheme proposed by C. C. Chang and C. H. Lin (1991) based upon Rabin´s public key cryptosystem is not secure enough. One of the attacks is based on the conspiracy of two users in the system while the other can be performed by anyone alone. It is shown that, in this second attack, the scheme can be broken by anyone (not necessarily a user in the system) who has the ability to observe the communications between the signer and the receiver
