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