SKINNY-64-64 is a lightweight block cipher with a 64-bit block length and key length,and it is mainly used on the Internet of Things(IoT).Currently,faults can be injected into cryptographic devices by attackers in a variety of ways,but it is still difficult to achieve a precisely located fault attacks at a low cost,whereas a hardware trojan(HT)can realize ***,as a physical quantity incidental to the operation of a cryptographic device,is easily *** this paper,a temperature-triggered HT(THT)is designed,which,when activated,causes a specific bit of the intermediate state of the SKINNY-64-64 to be ***,in this paper,a THT-based algebraic fault analysis(THT-AFA)method is *** demonstrate the effectiveness of the method,experiments on algebraic fault analysis(AFA)and THT-AFA have been carried out on *** the THT-AFA for SKINNY-64-64,it is only required to activate the THT 3 times to obtain the master key with a 100%success rate,and the average time for the attack is 64.57 ***,when performing AFA on this cipher,we provide a relation-ship between the number of different faults and the residual entropy of the *** comparison,our proposed THT-AFA method has better performance in terms of attack *** the best of our knowledge,this is the first HT attack on SKINNY-64-64.

hardware trojans in integrated circuit chips have the characteristics of being covert,destructive,and difficult to protect,which have seriously endangered the security of the chips themselves and the information systems to which they *** solutions generally rely on passive detection *** this paper,a hardware trojans active defense mechanism is designed for network switching chips based on the principle of encryption *** encoding the data entering the chip,the argot hidden in the data cannot trigger the hardware trojans that may exist in the chip,so that the chip can work normally even if it is implanted with a hardware *** proposed method is proved to be effective in preventing hardware trojans with different trigger characteristics by simulation tests and practical tests on our secure switching chip.

hardware security has become more and more important in current information security architecture. Recently collected reports have shown that there may have been considerable hardware attacks prepared for possible military usage from all over the world. Due to the intrinsic difference from software security, hardware security has some special features and challenges. In order to guarantee hardware security, academia has proposed the concept of trusted integrated circuits,which aims at a secure circulation of IC design, manufacture and chip using. This paper reviews the main problems of trusted integrated circuits, and concludes four key domains of the trusted IC, namely the trusted IC design, trusted manufacture,trusted IP protection, and trusted chip authentication. The main challenges in those domains are also analyzed based on the current known techniques. Finally, the main limitations of the current techniques and possible future trends are discussed.
