Strict Avalanche CriterionThe Strict Avalanche Criterion (SAC) is a property of boolean functions of relevance in cryptography. The SAC builds on the concepts of completeness and avalanche, and was introduced by Webster and Tavares in 1985. Definition A function is said to satisfy the strict avalanche criterion if, whenever a single input bit is complemented, each of the output bits should change with a probability of one half.
