Abstract
Techniques described herein enhance the durability of cryptographically protected communications sessions. The negotiation of a cryptographically protected communications session results in the negotiation of a primary secret and a secondary secret. The primary secret and secondary secret are stored in separate locations, such as in two locations in RAM, one of which being used as a RAM disk. The primary secret is used to cryptographically protect the communications session. Following the detection of a change of state event, the cryptographically protected communications session switches to the secondary secret in place of the primary secret to cryptographically protect the communications session.
