Security Terms

Encryption Engine

Also known as a mutation engine, this is a programming routine that uses cryptographic principles to "scramble" the malware code at each infection, creating a constantly mutating virus that is harder for security applications to detect.

Simple encryption engines used a static decryption routine, or key, that remained the same throughout all infections; virus scanners were therefore still able to detect malware encrypted by these engines by simply detecting the key. More sophisticated engines nowadays scramble both the malware code and the key at each new infection, creating a virus that can "change appearance" potentially millions of times, while performing the exact same functions each time. The constantly mutating code and key makes it significantly more difficult for virus scanners to detect the malware.

The term "encryption engine" can also be used to describe special software used by virus writers to produce encrypted, polymorphic code.
