Abstract
A security domain control method includes defining a sequential series of security domains; designating one of the security domains as a current domain; generating a plurality of security tokens under the current security domain, each security token being configured to enable a party to exchange cryptographically secured messages with another party that is holding any one of: a token generated under the current security domain; a token generated under at least one next security domain in the series; and a token generated under at least one previous security domain in the series; and subsequently designating a next one of the security domains in the series as a current domain.
