scramble

i. To encrypt any plain-language message during the transmission process so as to make it unintelligible to a third party.
ii. The whole action involved in getting interceptors into the air in the shortest time possible, sometimes without adequate warm-up. For an air defense mission, aircraft ordered to scramble are given the initial vector; the course to roll out and the height to climb to are also indicated in the scramble call and follow the word scramble (e.g., “Mission 70 scramble, scramble, initial vector 070°, angels 10”). Angels 10 means 10,000 ft altitude.

scramble

To make data indecipherable. The term stems from the early days of cryptography, which camouflaged analog transmissions by combining them with secret frequency patterns. Restoring the original frequencies is called "descrambling." Today, cryptography is mostly digital, and the 0 and 1 bits of digital data are rearranged into a different sequence. See cryptography.
