Abstract
A system for generating unique digital certificates is provided that generates computed hashes public keys and compares them. The system method computes a hash of a public key, compares the computed hash of the public key with hashes of public keys previously generated, generates the digital certificate having the public key and a device identifier only if the computed hash of the public key does not match any of the hashes of public keys previously generated, and provides the digital certificate.
