I made a merge request for optimizing AES modes on s390x architecture, the patch implements the optimized cores using cipher instructions that have been added to s390x arch in message security assist extensions. The patch uses the following functions: KM-AES-128 (ECB-AES128) KM-AES-192 (ECB-AES192) KM-AES-256 (ECB-AES256) KMC-AES-128 (CBC-AES128) KMC-AES-192 (CBC-AES192) KMC-AES-256 (CBC-AES256) KMAC-AES-128 (CCM-AES128, CMAC-AES128) KMAC-AES-192 (CCM-AES192) KMAC-AES-256 (CCM-AES256, CMAC-AES256) KMF-AES-128 (CFB-AES128, CFB8-AES128) KMF-AES-192 (CFB-AES192, CFB8-AES192) KMF-AES-256 (CFB-AES256, CFB8-AES256) KM-XTS-AES-128 (XTS-AES128) KM-XTS-AES-256 (XTS-AES256) KIMD-GHASH (GHASH) KMCTR-AES-128, KMA-GCM-AES-128 (CTR-AES128) KMCTR-AES-192, KMA-GCM-AES-192 (CTR-AES192) KMCTR-AES-256, KMA-GCM-AES-256 (CTR-AES256) KMA-GCM-AES-128 (GCM-AES128) KMA-GCM-AES-192 (GCM-AES192) KMA-GCM-AES-256 (GCM-AES256)
The merge request has also a benchmark that measures the speed of optimized cores on s390x arch. I can't set up gitlab CI for automatic testing on s390x arch because qemu hasn't implemented cipher functions for this arch. However, there is an easy way to test the patch manually by requesting a free account on the LinuxONE Community Cloud, both short-term and long-term access are available. https://linuxone.cloud.marist.edu/#/register?flag=VM regards, Mamone _______________________________________________ nettle-bugs mailing list nettle-bugs@lists.lysator.liu.se http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs
