Digital signature forgery : ウィキペディア英語版
Digital signature forgery
In a cryptographic digital signature or MAC system, digital signature forgery is the ability to create a pair consisting of a message m and a signature (or MAC) \sigma that is valid for m, where m has not been signed in the past by the legitimate signer. There are three types of forgery: existential, selective, and universal.
==Types==
Besides the following attacks, there is also a ''total break'': when adversary can compute the signer's private key and therefore forge any possible signature on any message
