摘要
A security chip-based security authentication method and system, a security chip, and a readable storage medium, relating to the technical field of secure communications. The security authentication method comprises: (1) a security chip (2) sends a key acquisition request to an auxiliary chip (3) in response to a security authentication request sent by an upper computer (10); (2) the auxiliary chip (3) sends first ciphertext data formed by encrypting a security key to the security chip (2) in response to the key acquisition request; (3) the security chip (2) decrypts the first ciphertext data to obtain the security key, and performs security authentication with the upper computer (10) in combination with code table data stored on the chip. The security key and the code table data required for security authentication are respectively stored into the security chip (2) and the auxiliary chip (3), so as to increase chip cracking difficulty and improve information security, and the method can be widely applied to the field of communication and authentication devices.
