一种基于时序型硬件木马的IP版权保护结构
A Sequential Hardware Trojan-based Framework for IP Copyright Protection
摘要
Abstract
With the widespread use of Intellectual Property ( IP ) in System-on-Chip ( SoC ) design, protection of hardware IP cores against piracy during evaluation becomes a major concern. Embedding a sequential hardware Trojan inside an IP is a new solution to protect the evaluation version of hardware IP. This paper proposes an advanced framework to lengthen the Trojan’ s activation time which is the decisive factor of the expiry date of an IP. The sequential Trojan is inserted in the unused states of a Finite State Machine( FSM) in the target circuit and some rare nodes making up a sequence can be chosen as Trojan trigger conditions,and the normal function of the IP core is disturbed when the Trojan is activated. Simulation results demonstrate that the improved framework can effectively lengthen the activation time of the inserted Trojan by 120 times and simultaneously reduce the design overhead by 0 . 123% when reasonably choosing the number of states as 3 and the length of sequence as 4 .关键词
