Random Key Chaining (RKC): AES Mode of Operation
There is a compelling need for a mode of operation that can efficiently provide authenticated encryption at a higher data rate, and is capable of making use of pipelining and parallel processing. This paper describes Random Key Chaining (RKC) block cipher mode of operation that fills this need. RKC mode makes use of Deterministic Random Bit Generator (DRBG) and with the application of DRBG ever...
متن کاملResource Saving AES-CCMP Design with Hybrid Counter Mode Block Chaining - MAC
IEEE 802.11i security standard is emerging as an essential security requirement to support the growth of a wide range of wireless data services and applications. However, with the advent of more battery powered wireless devices, efficient and robust cryptographic designs are needed that do not impose high computational overhead and avoid mismatch with limited battery resources and low processin...
متن کاملAES CCMP Algorithm with N-Way Interleaved Cipher Block Chaining
Nowadays, the increased use of battery-powered mobile appliances and the urge to access time-sensitive data anytime anywhere has fuelled a high demand for wireless networks. However, wireless networks are susceptible to intrusion and security problems. There is an inherent need to secure the wireless data communication to ensure the confidentiality, authenticity, integrity and non repudiation o...
متن کاملTransposition of AES Key Schedule
In this paper, we point out a new weakness of the AES key schedule by revisiting an old observation exploited by many known attacks. We also discover a major cause for this weakness is that the column-by-column word-wise property in the key schedule matches nicely with the MixColumns operation in the cipher’s diffusion layer. Then we propose a new key schedule by minor modification to increase ...
متن کاملComments to NIST concerning AES Modes of Operation: OCB Mode: Parallelizable Authenticated Encryption
This note describes a parallelizable block-cipher mode of operation that simultaneously provides privacy and authenticity. It does this using only djM j=ne + 2 block cipher invocations. Here M is the plaintext (an arbitrary bit string) and n is the block length. The scheme refines one recently suggested by Jutla [Ju00].
