A power 5G edge cloud identity authentication method, characterized in that: Applied to a server, the server and the terminal device store the same multiple public user public keys and multiple public server public keys, the method comprising: Receiving first authentication information and a first random number sent by a terminal device; Obtaining a terminal character string corresponding to a terminal identification of the terminal device, and calculating a user public key according to the terminal character string and the public user public key; Calculate the second authentication information according to the first random number, the server private key, and the user public key, wherein the calculation function of the first authentication information and the second authentication information is the same, and the server private key is calculated according to the server identifier of the server; If the first authentication information is the same as the second authentication information, determining that the terminal device is a legitimate user; The user public key is calculated by the following formula: Where n represents the number of public user keys. a represents the jth public user's public key j Power, a j is the jth character in the terminal string.

9. A computer device, characterized in that: include: at least one processor; And a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to execute the power 5G edge cloud authentication method as described in claim 7 or 8.

10. A computer-readable storage medium, characterized in that: The computer-readable storage medium stores computer instructions, and the computer instructions are used to enable the computer to execute the power 5G edge cloud authentication method as described in claim 7 or 8.
