ABSTRACT:
A computer apparatus, program and method function in a data processing system to replicate a cryptographic facility. The system includes a first cryptographic facility containing a portable part which personalizes the first cryptographic facility. The system also includes a second cryptographic facility which is linked to the first cryptographic facility by a public key cryptographic system. The portable part of the first cryptographic facility is encrypted and transferred to the second cryptographic facility, where it is decrypted and used to personalize the second cryptographic facility to enable replication of the first cryptographic facility. In one application, personalization of the second cryptographic facility can be in response to the detection of a failure in the first cryptographic facility. In another application, multiple cryptographic facilities can be brought on-line for parallel operation in the data processing system.
