Method and Apparatus for Verifiable Generation of Public Keys

摘要

The invention provides a method of verifiable generation of public keys. According to the method, a self-signed signature is first generated and then used as input to the generation of a pair of private and public keys. Verification of the signature proves that the keys are generated from a key generation process utilizing the signature. A certification authority can validate and verify a public key generated from a verifiable key generation process.

1. A computer implemented method of generating a private key of a computing device in a communication system, the computing device having a cryptographic unit, the method comprising:
said cryptographic unit generating a digital signature; said computing device obtaining message data; said cryptographic unit generating a self-signed signature message by combining said message data and said digital signature; and said cryptographic unit computing said private key using said self-signed signature message, said digital signature corresponding to a signature of the self-signed signature message.
