TSRC and Side Channel Security Requirement

This paper consists of two parts: First part de als with activities of TSRC. Second part is about TSRC comments on 140-3, which is primarily the same as the comments submitted to NIST last February, where we discussed that the forthcoming standards of cryptographic module should include the Side Channel Security Requirement (SCSR). Although SCSR may be described focusing on attack technique or countermeasure at the moment, it is important to develop and establish concrete metrics for the evaluation of tamper-resistance strength.
