| description | In recent years, there has been a rising interest in authenticated encryptionwith associated data (AEAD)which combines encryption
and authentication into a unified scheme. AEAD schemes provide authentication for a message that is divided into two parts:
associated data which is not encrypted and the plaintext which is encrypted. However, there is a lack of chaos-based AEAD
schemes in recent literature. This paper introduces a new128-bit chaos-based AEAD scheme based on the single-key Even-Mansour
and Type-II generalized Feistel structure. The proposed scheme provides both privacy and authentication in a single-pass using
only one 128-bit secret key. The chaotic tent map is used to generate whitening keys for the Even-Mansour construction, round
keys, and random s-boxes for the Feistel round function. In addition, the proposed AEAD scheme can be implemented with true
randomnumber generators to map a message tomultiple possible ciphertexts in a nondeterministic manner. Security and statistical
evaluation indicate that the proposed scheme is highly secure for both the ciphertext and the authentication tag. Furthermore, it
has multiple advantages over AES-GCM which is the current standard for authenticated encryption. |
