This invention relates to the field of public key infrastructure (PKI) technology and discloses a method and system for implementing a quantum-resistant hybrid certificate within PKI. The method generates a hybrid public key structure by combining and encapsulating a first type of public key and a second type of public key, and then performs double signing using the corresponding signature algorithm to form a hybrid cryptographic digital certificate. During verification, different types of public keys are used sequentially according to a specific pattern for verification. This method achieves the organic integration of multiple cryptographic systems, improves system compatibility and security, and can cope with the cryptographic threats posed by quantum computing.
