A security chip-based security authentication method and system, a security chip, and a readable storage medium are provided. The security authentication method includes: a security chip sending a key acquisition request to an auxiliary chip in response to a security authentication request sent by an upper computer; the auxiliary chip sending, to the security chip, first ciphertext data formed by encrypting a security key in response to the key acquisition request; the security chip decrypting the first ciphertext data to obtain the security key, and performing security authentication with the upper computer 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 and the auxiliary chip.

Security chip-based security authentication method and system, security chip, and readable storage medium

The present invention relates to the technical field of printer consumables, and particularly relates to a consumable chip, a consumable and a consumable communication method. A session key for communication authentication is determined based on a communication session chip count which is selected by the consumable chip and stored in a storage device. The calculation process of the communication session chip count is avoided, thereby increasing the response speed of the consumable chip for a read request of an imaging device, and reducing the error rate.

Consumable chip, consumable and consumable communication method

The present invention relates to the technical field of printer consumables, and particularly relates to a consumable chip, a consumable and a consumable communication method. The consumable chip directly executes a read request without verifying an imaging device check code in the read request of an imaging device, and then, the consumable chip can respond to the read request of the imaging device in time without being limited by an authentication mechanism of the imaging device, thereby increasing the response speed of the consumable chip to the read request of the imaging device, expanding the compatibility of the consumable chip for imaging devices of different types, and obtaining a certain fault-tolerant capability.
