Abstract : —ELmD Encrypt-Linear mix-Decrypt is a block-cipher based efficient authenticated encryption scheme, which is nonce misuse resistant, fully pipeline implementable. ELmD is a candidate for CAESAR competition and it has been selected for the second round. In this document, we first consider two versions of ELmDv2.0-i ELmD: full 10-round AES encryption-decryption, no intermediate tag, fixed tag size and ii ELmD6,6: 6-round AES encryption-decryption, no intermediate tag, fixed tag size. We provide the full specification for both the version and present hardware implementation of the combined encryption-decryption for both these versions. We discuss and compare the hardware performance of these versions with other popular AE schemes like COPA and OCB.
