METHOD OF PREVENTING UNAUTHORIZED DISTRIBUTION AND USE OF ELECTRONIC KEYS USING A KEY SEED.

摘要

A method and system for generating an electronic key used in an electronic transaction can be created by executing a one-way function on a host that derives the electronic key from a key seed saved in a on-volatile storage unit of the host and a unique host identification that is resident on the host. The function is preferably executed each time an electronic transaction requiring the use of the electronic key is made.
