Secure communication refers to the protection of communication content and the privacy and security of communication participants through various security mechanisms and technologies. In the field of communications, secure communication is crucial, especially in the age of the Internet. Traditional secure communication technologies typically rely on encryption algorithms and key exchange protocols to protect communication content from unauthorized access. However, with the increasing computational power of computers and advancements in cryptographic attack techniques, traditional encryption technologies may be vulnerable, thus necessitating more advanced security mechanisms to address these challenges.
