Abstract

This application provides a security evaluation method, a service processing method, a security information transmission method, and a related device, and relates to the field of communication technologies. The method includes: determining a target security evaluation result based on first security information in a case that a security evaluation request sent by an application server is received, where the first security information includes security status information of an REE of an electronic device or a security evaluation result of the REE; decrypting a first ciphertext by using a root key of the electronic device, to obtain a private key of the electronic device, where the first ciphertext is a ciphertext obtained by a security coprocessor by encrypting the private key of the electronic device by using the root key of the electronic device; signing the target security evaluation result by using the private key of the electronic device, to obtain a signature of the target security evaluation result; and sending second security information to the application server, where the second security information includes the target security evaluation result and the signature of the target security evaluation result.
