Abstract

The invention relates to a secure solid-state disk data transmission system based on a reconfigurable cryptographic processor, which relates to the technical field of data transmission. The inventionprovides a secure solid-state disk data transmission system based on a reconfigurable cryptographic processor, using a randomly dynamically configured encryption algorithm circuit in the time domain,Because the encryption algorithm used is randomly and dynamically configured over time, the attacker can not obtain the specific encryption form of each piece of data, thus eliminating the security hidden trouble that the attacker can carry out targeted attacks on the encryption algorithm, greatly increasing the attack difficulty of the attacker, and effectively improving the data security.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a secure solid-state disk data transmission system based on a reconfigurable cryptographic processor. Background technique [0002] Traditional secure SSDs use a single encryption algorithm to encrypt and decrypt data streams. Although a single encryption algorithm itself has certain reliability, with the rapid improvement of computing power, the security of a single encryption algorithm is getting lower and lower. Attackers can target A single encryption algorithm conducts targeted attacks, which brings security risks. [0003] The reconfigurable cryptographic processor can adjust its own internal operator usage and connection according to the transformation of external configuration information so as to change its own encryption algorithm. Static reconfiguration is to complete the reconfiguration of the processor and determine the encryption algorithm before the encr...
