In cryptography, message forgery is the sending of a message to deceive the recipient as to whom the real sender is. A common example is sending a spam e-mail as if it were originated from an address other than the one which was really used.

Forgery (MAC) — In a digital signature or Message Authentication Code (MAC) system, a Selective forgery is the creation (by an adversary) of chosen message m and a valid signature (or MAC) sigma for m, where m has not been signed or MACed in the past by the… … Wikipedia
Message authentication code — In cryptography, a message authentication code (often MAC) is a short piece of information used to authenticate a message. A MAC algorithm, sometimes called a keyed (cryptographic) hash function, accepts as input a secret key and an arbitrary… … Wikipedia
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) σ that is valid for m, where m has not been signed in the past by the legitimate… … Wikipedia
