Lightweight robust cryptographic combiner for mobile devices: Crypto roulette

The amount of data that requires secure transmission over heterogeneous networks has increased dramatically during the last decade and the trend is ongoing. This leads to increased performance and security demands on cryptographic systems. In this paper, a novel cryptographic system is proposed, named `Crypto Roulette´, which improves secrecy and robustness. This is accomplished by combining multiple symmetric cryptographic algorithms to create a cryptographic combiner. The throughput of the Crypto Roulette is compared to modern symmetric algorithms and cascade encryption algorithms.
