Summary:The invention discloses a secret key management method, and relates to the technical field of secret key management. According to secret key application information, an initial secret key is generated, a required coding segment is used on an initial secret key combination, a recordable secret key is generated, and in the subsequent work of decrypting an encrypted packet, the initial secret key is decrypted; the use condition of the recordable secret key can be determined according to the use requirement coding segment, and then the safety state of the recordable secret key is judged; according to a data processing flow requirement, behavior characteristics of a user in a data application process are analyzed and judged, then a key use requirement is determined according to the behavior characteristics, a current decryption state and the key use requirement are compared and analyzed, a security evaluation value of a recordable key is evaluated according to a comparison and analysis result, and the security eva
