Abstract
A method, a computer program product, and a system for binding post-quantum certificates to traditional certificates. The method includes selecting a traditional certificate in a certificate chain owned by an owner. The method also includes calculating a fingerprint of the traditional certificate. The method further includes generating a post-quantum certificate with identical information fields as the traditional certificate, and populating a serial number of the post-quantum certificate using the fingerprint. The post-quantum certificate acts as an extension of the first traditional certificate providing authentication and validation between a client and a server using post-quantum capable signing algorithms.
