LEA: A 128-Bit Block Cipher for Fast Encryption on Common Processors

We propose a new block cipher LEA, which has 128-bit block size and 128, 192, or 256-bit key size. It provides a high-speed software encryption on general-purpose processors. Our experiments show that LEA is faster than AES on Intel, AMD, ARM, and ColdFire platforms. LEA can be also implemented to h...

Summary:We propose a new block cipher LEA, which has 128-bit block size and 128, 192, or 256-bit key size. It provides a high-speed software encryption on general-purpose processors. Our experiments show that LEA is faster than AES on Intel, AMD, ARM, and ColdFire platforms. LEA can be also implemented to have tiny code size. Its hardware implementation has a competitive throughput per area. It is secure against all the existing attacks on block ciphers.
