Energy-Efficient AES Ciphers on a Fine-Grained Many-Core System

چکیده
By exploring different granularities of data-level and task-level parallelism, we propose 16 implementations of an Advanced Encryption Standard (AES) cipher with both online and offline key expansion on a fine-grained many-core system. The smallest design utilizes only 6 cores for offline key expansion and 8 cores for online key expansion, while the largest requires 107 cores and 137 cores, respectively. With frequency and voltage scaling, the power of different implementations could be reduced as much as 32%. In comparison with published AES cipher implementations on other software platforms, our design has 3.3– 15.6 times higher throughput per chip area and 3.4–21.7 times higher energy efficiency.

متن کاملA Mathematical Framework for Combining Error Correction and Encryption
Error resilience and energy efficiency are two main challenges facing block ciphers in noisy and resource constrained wireless environments. Traditionally, error correcting codes are used to recover from channel induced errors. However, this two step operation: encryption followed by error correction adds extra burden on an already resource constrained environment. Combining the two operations ...

This paper presents three energy-efficient methods for searching and filtering streamed data on a fine-grained manycore processor array: parallel, serial, and all-in-one. All three architectures aim to provide programmable flexibility with low energy consumption. Experimental results show that for one keyword search, the parallel and serial architectures consume 2× less energy per workload than...
