1 The GCM test vectors in this directory were downloaded from the NIST 2 Cryptographic Algorithm Validation Program (CAVP) website 3 (http://csrc.nist.gov/groups/STM/cavp/) on Mar 29, 2013 using the URL 4 http://csrc.nist.gov/groups/STM/cavp/documents/mac/gcmtestvectors.zip. 5 6 The original test files are about 3 MB each, which are too big to 7 include in the NSS source tree. I observed the following patterns in 8 the test vectors: 9 1. Taglen changes in a cycle of 7: 128, 120, 112, 104, 96, 64, 32. 10 2. Then, AADlen changes in a cycle of 5: 0, 128, 160, 384, 720. 11 12 To reduce the number of test vectors, I kept Taglen = 128, 96 from 13 each cycle of 7, and kept AADlen = 0, 720, 160 from each two cycles 14 of 10.
