Trust Management systems are trust infrastructures that support authorization for security-critical actions in decentralized environments. We investigate extension suitable for multi-domain applications in variable-threat environments that allow for temporary adjustments of trust levels in response to elevated threat levels, and which can be reversed without compromising actions that took place during such periods—we term this, rollback-access. We argue that a rollback-access capability is an essential feature for security-critical applications, and propose a working prototype for an agent based implementation.
