Abstract

In some embodiments, an apparatus comprises a certificate store to store a current certificate associated with a key pair including a current public key and a current private key; a policy decision point (PDP) module to monitor the certificate store and to ascertain whether the current certificate has expired or is expiring; and a key manager, based at least in part on the PDP module determining that the current certificate has expired or is expiring, being adapted to identify encrypted information encrypted with an encrypting key of the key pair and to decrypt the encrypted information with a decrypting key of the key pair to obtain unencrypted information.
