For the x86_64 environment, we use AVX-512F/AVX2/SSE2 instructions.
Since LEA uses 128-bit blocks of four 32-bit integers, for optimization,
SSE2 encrypts 4 blocks, AVX2 encrypts 4/8 blocks, and AVX-512F encrypts
4/8/16 blocks at a time.
Our submission provides a optimized implementation of ECB, CBC
decryption, CTR, and XTS cipher operation modes on x86_64 CPUs
supporting.

+ LEA is a 128-bit lightweight block cipher developed by South Korea.
+
+ LEA is the a Korean standard (KS X 3246) and is included in the
+ ISO/IEC 29192-2:2019 standard (Information security - Lightweight
+ cryptography - Part 2: Block ciphers).
+
+ It consists of 32-bit integer addition, rotation, and XOR, which can
+ be performed effectively on CPUs that support 32-bit operations.
+
+ It supports 128-bit, 192-bit, and 256-bit keys.
+
+ See:

+ Architecture: x86_64 using:
