Abstract: With the further improvement of design,manufacture and test separation in Integrated Circuits(IC),hardware trojans can be implemented as modifications to IC,and it raises numerous concerns regarding possible threats.This paper briefly explains the concept of hardware trojans,and explains the countermeasures technology of hardware trojan attacks and the importance of conducting out the countermeasures against hardware trojans.Also it introduces the classification of the state-of-art countermeasures,deeply analyzes the side-channel analysis method and the design for security method.Analysis results show that the designers must consider circuit security problem in designing circuits in onder to the security of integrated circuits,meanwhile they begin test works ensure after chips are completed.

Key words: Integrated Circuits(IC), hardware trojans, countermeasures technology, side-channel analysis, security design
