This paper presents state of the art review of cryptographic practices as well as a performance evaluation of symmetric key encryption algorithms on an Allwinner A13 based ARM embedded system part of a fall detection Ambient Assisted Living solution. The evaluated algorithms are 5 modes of the AES (Advanced Encryption Standard) symmetric encryption algorithm.

This paper presents an area optimized for composite field arithmetic based SubBytes transformation (Sbox) used in Advanced Encryption Standard (AES) encryption. The proposed architecture is based on precomputation technique. Implementation is proposed on FPGA using Xilinx ISE on XC3S 400-5 and results are shown in the paper. Keywords—AES, S-BOX, Sub-Byte, Encryption.

The performance of a single-chip shared-memory multiprocessor system for encryption/decryption of large quantities of information is examined. The multiprocessor uses an asynchronous bus system to increase scalability and to reduce design effort. The target application is the Advanced Encryption Standard (AES) with 128 bit key. Chip area requirements and encryption/decryption throughput rates a...

We make a number of remarks about the AES-GCM-SIV nonce-misuse resistant authenticated encryption scheme currently considered for standardization by the Crypto Forum Research Group (CFRG). First, we point out that the security analysis proposed in the ePrint report 2017/168 is incorrect, leading to overly optimistic security claims. We correct the bound and re-assess the security guarantees off...

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...
