ice n.

[coined by Usenetter Tom Maddox, popularized by William

Gibson's cyberpunk SF novels: a contrived acronym for `Intrusion

Countermeasure Electronics'] Security software (in Gibson's

novels, software that responds to intrusion by attempting to

immobilize or even literally kill the intruder). Hence,

`icebreaker': a program designed for cracking security on a

system.

Neither term is in serious use yet as of early 1999, but many

hackers find the metaphor attractive, and each may develop a

denotation in the future. In the meantime, the speculative usage

could be confused with `ICE', an acronym for "in-circuit

emulator".

In ironic reference to the speculative usage, however, some

hackers and computer scientists formed ICE (International

Cryptographic Experiment) in 1994. ICE is a consortium to promote

uniform international access to strong cryptography.
