Abstract
A public key sterilization scheme for thwarting possible attacks based on choosing malicious public keys. A first user sends public key information to a certificate authority. The certificate authority manipulates the public key information, and sends certified version of the public key information to the first user. The first user verifies the certified key, and calculates a second private key.
