A Submission to CAESAR Competition for Authenticated Encryption
نویسندگان
چکیده
This paper presents the Code-Book Authentication mode (CBA), a submission to the CAESAR competition for authenticated encryption. CBA is a blockcipher mode of encryption that provides confidentiality and authenticity for plaintexts and authenticity for associated data. The proposed mode improves the OCB mode in the sense that it saves up to one blockcipher call to encrypt and authenticate the plaintext. The CBA mode is one pass, uses one-key for encryption and authentication and employs a fixed-length arbitrary nonce.

General classification of the authenticated encryption schemes for the CAESAR competition
An Authenticated encryption scheme is a scheme which provides privacy and integrity by using a secret key. In 2013, CAESAR (the “Competition for Authenticated Encryption: Security, Applicability, and Robustness”) was co-founded by NIST and Dan Bernstein with the aim of finding authenticated encryption schemes that offer advantages over AES-GCM and are suitable for widespread adoption. The first...
متن کاملCryptanalysis of Submission to the CAESAR Cryptographic Competition iFeed
iFeed is a blockcipher-based authenticated encryption design by Zhang, et al. [81] and a candidate to the CAESAR competition. iFeed is claimed to achieve confidentiality and authenticity in the nonce-respecting setting, and confidentiality in the noncereuse setting. In this thesis, we consider the security of iFeed in three settings. In the noncerespecting setting we show a forgery and subkey r...
متن کاملWho can survive in CAESAR competition at round-zero?
Cryptographic primitives are required to protect an IT (Information Technology) system. They are used to provide CIA (Confidentiality, Integrity, and Availability) and other security attributes to the system. So far, NIST (National Institute of Standard and Technology) has successfully standardized AES (Advanced Encryption Standard) for confidentiality and SHA (Secure Hash Algorithm) for integr...
متن کاملBeyond 2 c/2 Security in Sponge-Based Authenticated Encryption Modes
The Sponge function is known to achieve 2 security, where c is its capacity. This bound was carried over to keyed variants of the function, such as SpongeWrap, to achieve a min{2, 2} security bound, with κ the key length. Similarly, many CAESAR competition submissions are designed to comply with the classical 2 security bound. We show that Spongebased constructions for authenticated encryption ...
متن کاملAE5 Security Notions: Definitions Implicit in the CAESAR Call
A draft call for the CAESAR authenticated-encryption competition adopts an interface that is not aligned with existing definitions in the literature. It is the purpose of this brief note to formalize what we believe to be the intended definitions.
