|
|
* Even though permitted values for TABLE_BITS are 8, 4 and 1, it should
|
|
* never be set to 8. 8 is effectively reserved for testing purposes.
|
|
* TABLE_BITS>1 are lookup-table-driven implementations referred to as
|
|
* "Shoup's" in GCM specification. In other words OpenSSL does not cover
|
|
* whole spectrum of possible table driven implementations. Why? In
|
|
* non-"Shoup's" case memory access pattern is segmented in such manner,
|
|
* that it's trivial to see that cache timing information can reveal
|
|
* fair portion of intermediate hash value. Given that ciphertext is
|
|
* always available to attacker, it's possible for him to attempt to
|
|
* deduce secret parameter H and if successful, tamper with messages
|
|
* [which is nothing but trivial in CTR mode]. In "Shoup's" case it's
|
|
* not as trivial, but there is no reason to believe that it's resistant
|
|
* to cache-timing attack. And the thing about "8-bit" implementation is
|
|
* that it consumes 16 (sixteen) times more memory, 4KB per individual
|
|
* key + 1KB shared. Well, on pros side it should be twice as fast as
|
|
* "4-bit" version. And for gcc-generated x86[_64] code, "8-bit" version
|
|
* was observed to run ~75% faster, closer to 100% for commercial
|
|
* compilers... Yet "4-bit" procedure is preferred, because it's
|
|
* believed to provide better security-performance balance and adequate
|
|
* all-round performance. "All-round" refers to things like:
|
|
*
|
|
* - shorter setup time effectively improves overall timing for
|
|
* handling short messages;
|
|
* - larger table allocation can become unbearable because of VM
|
|
* subsystem penalties (for example on Windows large enough free
|
|
* results in VM working set trimming, meaning that consequent
|
|
* malloc would immediately incur working set expansion);
|
|
* - larger table has larger cache footprint, which can affect
|
|
* performance of other code paths (not necessarily even from same
|
|
* thread in Hyper-Threading world);
|
|
*
|
|
* Value of 1 is not appropriate for performance reasons.
