Abstract:
A method for remotely rekeying a cryptographic device, comprising:associating a preliminary certificate with the device; generating a device certificate associated with the device, wherein the device certificate has a public part and a private part; determining whether a certificate stored in the device is the preliminary certificate associated with the device; and if the certificate stored in the device is the preliminary certificate associated with the device, then securely loading the device certificate into the device by encrypting the private part of the device certificate using a first encryption algorithm, generating a first packet comprising the public part, the encrypted private part, and a set of decryption instructions for decrypting the encrypted private part, encrypting the first packet using a second encryption algorithm, generating a second packet comprising the encrypted first packet and a set of decryption instructions for decrypting the encrypted first packet, and delivering the second packet to the device.
