Abstract

The invention discloses a safety reconfigurable framework capable of resisting power dissipation attack, which comprises a multi-line reconfigurable array operation line, a line controller, a general register file, a register, an input cache, an output cache, a reconfigurable search table, a first multichannel data selector, a secret share safety protection module and a data path dynamic reconfiguration safety protection module, wherein the reconfigurable search table comprises an arithmetical logic unit, a data replacing network, a data loading unit and a data output unit; the secret share safety protection module comprises a second multichannel data selector, an XOR operation module, a data cache module and a first random number generator; the data path dynamic reconfiguration safety protection module comprises a third multichannel data selector, a fourth multichannel data selector, a second random number generator, a third random number generator, a first delay data channel and a second delay data channel. The safety reconfigurable framework has advantages of guaranteeing safety while greatly reducing area and performance cost.

Description

technical field [0001] The invention relates to an embedded reconfigurable system architecture, in particular to a safe reconfigurable architecture resistant to power consumption attacks. Background technique [0002] As the cornerstone of information security, cryptographic algorithms in the information age often take on the responsibility of protecting sensitive information. In order to meet the encryption needs of various occasions, high requirements are put forward for the carrier of the encryption algorithm in terms of encryption efficiency and flexibility. Traditionally, the implementation forms of encryption mainly include general-purpose processor implementation and application-specific integrated circuit implementation. However, with the increasing demand for system performance, energy consumption, time-to-market and other indicators in the application field, the disadvantages of these two traditional implementation methods are exposed. [0003] The general-purpos...
