The fiat-crypto-generated code uses the Montgomery form implementation strategy, for both 32-bit and 64-bit code. 64-bit throughput seems slower, but the difference is smaller than noise between repetitions (-2%?) 32-bit throughput has decreased significantly for ECDH (-40%). I am attributing this to the change from varibale-time scalar multiplication to constant-time scalar multiplication. Due to the same bottleneck, ECDSA verification still uses the old code (otherwise there would have been a 60% throughput decrease). On the other hand, ECDSA signing throughput has increased slightly (+10%), perhaps due to the use of a precomputed table of multiples of the base point. 64-bit benchmarks (Google Cloud Haswell): with this change: Did 9126 ECDH P-256 operations in 1009572us (9039.5 ops/sec) Did 23000 ECDSA P-256 signing operations in 1039832us (22119.0 ops/sec) Did 8820 ECDSA P-256 verify operations in 1024242us (8611.2 ops/sec) master (40e8c921ca): Did 9340 ECDH P-256 operations in 1017975us (9175.1 ops/sec) Did 23000 ECDSA P-256 signing operations in 1039820us (22119.2 ops/sec) Did 8688 ECDSA P-256 verify operations in 1021108us (8508.4 ops/sec) benchmarks on ARMv7 (LG Nexus 4): with this change: Did 150 ECDH P-256 operations in 1029726us (145.7 ops/sec) Did 506 ECDSA P-256 signing operations in 1065192us (475.0 ops/sec) Did 363 ECDSA P-256 verify operations in 1033298us (351.3 ops/sec) master (2fce1beda0): Did 245 ECDH P-256 operations in 1017518us (240.8 ops/sec) Did 473 ECDSA P-256 signing operations in 1086281us (435.4 ops/sec) Did 360 ECDSA P-256 verify operations in 1003846us (358.6 ops/sec) 64-bit tables converted as follows: import re, sys, math p = 2**256 - 2**224 + 2**192 + 2**96 - 1 R = 2**256 def convert(t): x0, s1, x1, s2, x2, s3, x3 = t.groups() v = int(x0, 0) + 2**64 * (int(x1, 0) + 2**64*(int(x2,0) + 2**64*(int(x3, 0)) )) w = v*R%p y0 = hex(w%(2**64)) y1 = hex((w>>64)%(2**64)) y2 = hex((w>>(2*64))%(2**64)) y3 = hex((w>>(3*64))%(2**64)) ww = int(y0, 0) + 2**64 * (int(y1, 0) + 2**64*(int(y2,0) + 2**64*(int(y3, 0)) )) if ww != v*R%p: print(x0,x1,x2,x3) print(hex(v)) print(y0,y1,y2,y3) print(hex(w)) print(hex(ww)) assert 0 return '{'+y0+s1+y1+s2+y2+s3+y3+'}' fe_re = re.compile('{'+r'(\s*,\s*)'.join(r'(\d+|0x[abcdefABCDEF0123456789]+)' for i in range(4)) + '}') print (re.sub(fe_re, convert, sys.stdin.read()).rstrip('\n')) 32-bit tables converted from 64-bit tables Change-Id: I52d6e5504fcb6ca2e8b0ee13727f4500c80c1799 Reviewed-on: https://boringssl-review.googlesource.com/23244 Commit-Queue: Adam Langley <agl@google.com> Reviewed-by: Adam Langley <agl@google.com> CQ-Verified: CQ bot account: commit-bot@chromium.org <commit-bot@chromium.org>
