======================================================================== README for Intel(R) Multi-Buffer Crypto for IPsec Library March 2018 ======================================================================== Contents ======== - Overview - Processor Extensions - Recommendations - Package Content - Compilation - Installation - Legal Disclaimer Overview ======== Intel Multi-Buffer Crypto for IPsec Library is highly-optimized software implementations of the core cryptographic processing for IPsec, which provides industry-leading performance on a range of Intel(R) Processors. For information on how to build and use this library, see the Intel White Paper: "Fast Multi-buffer IPsec Implementations on Intel Architecture Processors". Jim Guilford, Sean Gulley, et. al. The easiest way to find it is to search the Internet for the title and Intel White Paper. Table 1. List of supported cipher algorithms and their implementations. +---------------------------------------------------------------------+ | | Implementation | | Encryption +-----------------------------------------------------| | | x86_64 | SSE | AVX | AVX2 | AVX512 | VAES(5)| |---------------+--------+--------+--------+--------+--------+--------| | AES128-GCM | N | Y by8 | Y by8 | Y by8 | Y by8 | Y by48 | | AES192-GCM | N | Y by8 | Y by8 | Y by8 | Y by8 | Y by48 | | AES256-GCM | N | Y by8 | Y by8 | Y by8 | Y by8 | Y by48 | | AES128-CCM | N | Y by4 | Y by8 | N | N | N | | AES128-CBC | N | Y(1) | Y(3) | N | N | Y(6) | | AES192-CBC | N | Y(1) | Y(3) | N | N | Y(6) | | AES256-CBC | N | Y(1) | Y(3) | N | N | Y(6) | | AES128-CTR | N | Y by4 | Y by8 | N | N | Y by16 | | AES192-CTR | N | Y by4 | Y by8 | N | N | Y by16 | | AES256-CTR | N | Y by4 | Y by8 | N | N | Y by16 | | AES128-ECB | N | Y by4 | Y by4 | N | N | N | | AES192-ECB | N | Y by4 | Y by4 | N | N | N | | AES256-ECB | N | Y by4 | Y by4 | N | N | N | | NULL | Y | N | N | N | N | N | | AES128-DOCSIS | N | Y(2) | Y(4) | N | N | N | | DES-DOCSIS | Y | N | N | N | Y x16 | N | | 3DES | Y | N | N | N | Y x16 | N | | DES | Y | N | N | N | Y x16 | N | | KASUMI-F8 | Y | N | N | N | N | N | | ZUC-EEA3 | N | Y | Y | N | N | N | | SNOW3G-UEA2 | N | Y | Y | Y | N | N | +---------------------------------------------------------------------+ Notes: (1,2) - decryption is by4 and encryption is x4 (3,4) - decryption is by8 and encryption is x8 (5) - AVX512 plus VAES and VPCLMULQDQ extensions (6) - decryption is by16 and encryption is x16 Legend: byY - single buffer Y blocks at a time xY - Y buffers at a time As an example of how to read table 1 and 2, if one uses AVX512 interface to perform AES128-CBC encryption then there is no native AVX512 implementation for this cipher. In such case, the library uses best available implementation which is AVX for AES128-CBC. Table 2.

For more build options and their explanation run: > gmake help Safety options ============== There are two build options that can be enabled to increase safety in the code and protecting external functions from incorrect input data. These options are disabled by default, due to the performance impact associated to the extra code added. These options (explained below) can be enabled when building the library, by setting the parameter equal to "y" (e.g. make SAFE_DATA=y). No specific code has been added, and no specific validation or security tests have been performed to protect against or check for side-channel attacks. SAFE_DATA --------- Stack and registers containing sensitive information, such as keys or IVs, are cleared upon completion of a function call. SAFE_PARAM ---------- Input parameters are checked, looking generally for NULL pointers or an incorrect input length.
