A new authenticated encryption (AE) mode for blockcipher is presented. The proposed scheme has attractive features for fast and compact operation. It requires rate-1 blockcipher call, and uses the encryption function of a blockcipher for both encryption and decryption. Moreover, the scheme enables one-pass, parallel operation under two-block partition. The proposed scheme thus attains similar characteristics as the seminal OCB mode, without using the inverse blockcipher. The key idea of our… CONTINUE READING
