摘要：The security of smart substation encrypted messages rests with the security of cryptosystems. The security of cryptosystems depends on the protection of keys. It can ensure the security of cryptographic systems and messages by ensuring that no keys are compromised. The key security problem is the key to modem information security in cryptography, and it is also a problem that smart substation information security solutions must solve. Therefore, a secure and reliable key management module is used to ensure that keys are securely and efficiently shared among authorized parties, the security of cryptographic systems and messages, and it is particularly important to meet the requirements for real-time, availability, and confidentiality of smart substations.
