34 # ECB, CTR, CBC and CCM results are free from EVP overhead. This means
35 # that otherwise used 'openssl speed -evp aes-128-??? -engine aesni
36 # [-decrypt]' will exhibit 10-15% worse results for smaller blocks.
37 # The results were collected with specially crafted speed.c benchmark
38 # in order to compare them with results reported in "Intel Advanced
39 # Encryption Standard (AES) New Instruction Set" White Paper Revision
40 # 3.0 dated May 2010. All above results are consistently better. This
41 # module also provides better performance for block sizes smaller than
42 # 128 bytes in points *not* represented in the above table.
44 # Looking at the results for 8-KB buffer.
46 # CFB and OFB results are far from the limit, because implementation
47 # uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on
48 # single-block aesni_encrypt, which is not the most optimal way to go.
49 # CBC encrypt result is unexpectedly high and there is no documented
50 # explanation for it. Seemingly there is a small penalty for feeding
51 # the result back to AES unit the way it's done in CBC mode. There is
52 # nothing one can do and the result appears optimal. CCM result is
53 # identical to CBC, because CBC-MAC is essentially CBC encrypt without
54 # saving output. CCM CTR "stays invisible," because it's neatly
55 # interleaved wih CBC-MAC. This provides ~30% improvement over
56 # "straghtforward" CCM implementation with CTR and CBC-MAC performed
57 # disjointly. Parallelizable modes practically achieve the theoretical
60 # Looking at how results vary with buffer size.
62 # Curves are practically saturated at 1-KB buffer size. In most cases
63 # "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one.
64 # CTR curve doesn't follow this pattern and is "slowest" changing one
65 # with "256-byte" result being 87% of "8-KB." This is because overhead
66 # in CTR mode is most computationally intensive. Small-block CCM
67 # decrypt is slower than encrypt, because first CTR and last CBC-MAC
68 # iterations can't be interleaved.
70 # Results for 192- and 256-bit keys.
72 # EVP-free results were observed to scale perfectly with number of
73 # rounds for larger block sizes, i.e. 192-bit result being 10/12 times
74 # lower and 256-bit one - 10/14. Well, in CBC encrypt case differences
75 # are a tad smaller, because the above mentioned penalty biases all
76 # results by same constant value. In similar way function call
77 # overhead affects small-block performance, as well as OFB and CFB
78 # results. Differences are not large, most common coefficients are
79 # 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one
80 # observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)...
84 # While Westmere processor features 6 cycles latency for aes[enc|dec]
85 # instructions, which can be scheduled every second cycle, Sandy
86 # Bridge spends 8 cycles per instruction, but it can schedule them
87 # every cycle. This means that code targeting Westmere would perform
88 # suboptimally on Sandy Bridge. Therefore this update.
90 # In addition, non-parallelizable CBC encrypt (as well as CCM) is
91 # optimized. Relative improvement might appear modest, 8% on Westmere,
92 # but in absolute terms it's 3.77 cycles per byte encrypted with
93 # 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers
94 # should be compared to asymptotic limits of 3.75 for Westmere and
95 # 5.00 for Sandy Bridge. Actually, the fact that they get this close
96 # to asymptotic limits is quite amazing. Indeed, the limit is
97 # calculated as latency times number of rounds, 10 for 128-bit key,
98 # and divided by 16, the number of bytes in block, or in other words
99 # it accounts *solely* for aesenc instructions. But there are extra
100 # instructions, and numbers so close to the asymptotic limits mean
101 # that it's as if it takes as little as *one* additional cycle to
102 # execute all of them. How is it possible? It is possible thanks to
103 # out-of-order execution logic, which manages to overlap post-
104 # processing of previous block, things like saving the output, with
105 # actual encryption of current block, as well as pre-processing of
106 # current block, things like fetching input and xor-ing it with
107 # 0-round element of the key schedule, with actual encryption of
108 # previous block. Keep this in mind...
110 # For parallelizable modes, such as ECB, CBC decrypt, CTR, higher
111 # performance is achieved by interleaving instructions working on
112 # independent blocks. In which case asymptotic limit for such modes
113 # can be obtained by dividing above mentioned numbers by AES
114 # instructions' interleave factor. Westmere can execute at most 3
115 # instructions at a time, meaning that optimal interleave factor is 3,
116 # and that's where the "magic" number of 1.25 come from. "Optimal
117 # interleave factor" means that increase of interleave factor does
118 # not improve performance. The formula has proven to reflect reality
119 # pretty well on Westmere... Sandy Bridge on the other hand can
120 # execute up to 8 AES instructions at a time, so how does varying
121 # interleave factor affect the performance? Here is table for ECB
122 # (numbers are cycles per byte processed with 128-bit key):
124 # instruction interleave factor 3x 6x 8x
125 # theoretical asymptotic limit 1.67 0.83 0.625
126 # measured performance for 8KB block 1.05 0.86 0.84
128 # "as if" interleave factor 4.7x 5.8x 6.0x
130 # Further data for other parallelizable modes:
132 # CBC decrypt 1.16 0.93 0.74
135 # Well, given 3x column it's probably inappropriate to call the limit
136 # asymptotic, if it can be surpassed, isn't it? What happens there?
137 # Rewind to CBC paragraph for the answer. Yes, out-of-order execution
138 # magic is responsible for this. Processor overlaps not only the
139 # additional instructions with AES ones, but even AES instuctions
140 # processing adjacent triplets of independent blocks. In the 6x case
141 # additional instructions still claim disproportionally small amount
142 # of additional cycles, but in 8x case number of instructions must be
143 # a tad too high for out-of-order logic to cope with, and AES unit
144 # remains underutilized... As you can see 8x interleave is hardly
145 # justifiable, so there no need to feel bad that 32-bit aesni-x86.pl
146 # utilizies 6x interleave because of limited register bank capacity.
148 # Higher interleave factors do have negative impact on Westmere
149 # performance. While for ECB mode it's negligible ~1.5%, other
150 # parallelizables perform ~5% worse, which is outweighed by ~25%
151 # improvement on Sandy Bridge. To balance regression on Westmere
152 # CTR mode was implemented with 6x aesenc interleave factor.
156 # Add aesni_xts_[en|de]crypt. Westmere spends 1.25 cycles processing
157 # one byte out of 8KB with 128-bit key, Sandy Bridge - 0.90. Just like
158 # in CTR mode AES instruction interleave factor was chosen to be 6x.
