Abstract
A method, a computer program product, and a system for embedding a message in a random value. The method includes generating a random value and applying a hash function to the random value to produce a hash value. Starting with the hash value, the method further includes reapplying the hash function in an iterative or recursive manner, with a new hash value produced by the hash function acting as an initial value that is applied to the hash function for a next iteration, until a bit sequence representing a message is produced in a message hash value. The method further includes utilizing the message hash value as a new random value that can be used by an encryption algorithm.
