Each variant key has been generated by applying a one way function to: a base key; and one or more of the at least one bit-patterns, respectively; or one or more alternative bit patterns. Each alternative bit-pattern is based on one of the at least one bit-patterns. In the method, it is determined that the predetermined event has happened, and at least one of the first variant keys is enabled or disabled in response to the predetermined event.
