The pur

30、pose of this document is to address conformance testing methods of cryptographic algorithms and security mechanisms implemented in a cryptographic module. This will allow a complete security evaluation of both the cryptographic module and the implemented cryptographic algorithms and security mechani

31、sms. This document is related to ISO/IEC 19790 and ISO/IEC 24759. ISO/IEC 19790 specifies the security requirements for cryptographic modules. At a minimum, a cryptographic module implements at least one approved security function (i.e., cryptographic algorithm or security mechanism). ISO/IEC 24759

32、addresses the test requirements for each of the security requirements in ISO/IEC 19790. However, ISO/IEC 24759 does not address test methods for cryptographic algorithms and security mechanisms conformance testing.vi ISO/IEC 2016 All rights reservedBS ISO/IEC 18367:2016Information technology Securit

Conformance testing assures that an implementation of a cryptographic algorithm or security mecha

34、nism is correct whether implemented in hardware, software or firmware. It also confirms that it runs correctly in a specific operating environment. Testing can consist of known-answer or Monte Carlo testing, or a combination of test methods. Testing can be performed on the actual implementation or m

35、odelled in a simulation environment. This document does not include the efficiency of the algorithms or security mechanisms nor the intrinsic performance. This document focuses on the correctness of the implementation. 2 Normative references The following documents are referred to in the text in suc
