LIGHTWEIGHT ENCRYPTION ALGORITHM SECURITY APPARATUS BASED ON HARDWARE AUTHENTICATION CHIP

摘要

The present invention relates to a lightweight cryptographic algorithm security device based on a hardware authentication chip, comprising: a plurality of secure partitions for storing a plurality of second partial key elements used to generate a symmetric key that can be generated through a first partial key element A memory divided into a memory, and storing the first partial key element and performing encryption or decryption of a plain text based on a symmetric key generated as one of the first partial key element and the plurality of second partial key elements And a processor that selects one of the plurality of security partitions according to an acceleration chip and a request for encryption or decryption to obtain a corresponding second partial key element and provide the second partial key element to the security acceleration chip. Therefore, the present invention can enhance the security by managing the secret key used in the lightweight encryption algorithm.
