Abstract
A signature system, such as an El Gamal or DSS system, involving the use of a long-term secret number and a per-message secret number generates the per-message secret number without the use of a random number generator or non-volatile storage. The per-message secret number is generated by applying a one-way hash function to a combination of the long-term secret number and the message itself.
