Parallel Model for Rabbit Stream Cipher over Multi-Core Processors
Author:
Abstract: This paper presents a new parallel model for Rabbit stream cipher. The goal of this model is to enhance the performance of Rabbit cipher by accelerating its keystream generation and encryption processes. The underlying concept of the new model was built based on utilizing multi-core processors to generate multiple keystreams simultaneously. The results showed that the new parallel model could enhance the encryption speed of Rabbit of about 1.4, 1.6 and 2.3 times on single, dual and quad core processors.
