DSC0005 - FCS_COP.1/Hash Incorrect Testing Description

SD_DSC_v1.0

FCS_COP.1/Hash

In section 2.1.3.1.3, paragraph 62, the test requirements have the evaluator generate a set of 100 messages and associated digests to ensure the implementation of the algorithm. This is an incorrect description of the necessary test.

The test description is updated to correctly explain the testing requirements.

The SD is updated as follows (yellow highlights for additions, strikethrough for deletions) per section that is being updated:

2.1.3.1.3 Test

Pseudo-randomly Generated Messages Test

The evaluators randomly generate a seed that is n bits long, where n is the length of the message digest produced by the hash function to be tested. The evaluators then formulate a set of 100 messages and associated digests by following the algorithm provided in Figure 1 of SHAVS, section 6.4. This seed is used by a pseudorandom function to generate 100,000 message digests. One hundred of the digests (every 1,000th digest) are recorded as checkpoints by following the algorithm provided in Figure 1 of SHAVS, section 6.4. The TOE then uses the same procedure to generate the same 100,000 message digests and 100 checkpoint values. The evaluators then ensure that the correct result is produced when the messages are provided to the TSF.
