A secure communication system or method are disclosed that may employ a constant level of trust between participants and a security management entity. As part of the constant level of trust, a communication policy may cause participants to request key validation every time the participant wishes to take an action that requires use of a key. In this manner, the participant may regularly communicate with the security management, and this regular communication can be further used to implement key renewal and/or rollover procedures. |
