  • an interface to a memory which stores a plurality of encrypted records, each encrypted record having an associated asymmetric encryption key pair and being encrypted with a first component of the associated asymmetric encryption key pair;

    at least one automated processor operating in a privileged processing environment, configured to receive a selected encrypted record from the memory through the interface, to negotiate at least one asymmetric session key, and to transcrypt the encrypted message to a transcrypted message in an integral process substantially without intermediate decryption, using a transcryption key derived at least in part from the at least one asymmetric session key; and

    a communication port configured to conduct the negotiation for the at least one asymmetric session key and to communicate the transcrypted record.
