A New Chaos Encryption Algorithm Based on Parameter Randomly Changing

Abstract

The paper proposed a new encryption algorithm of one dimension chaotic map, which based on parameter randomly changing. Through the randomly changing of parameter and iteration times, the complicated degree of chaotic sequences and cryptographic specific property are strengthened, and improved algorithm has n times long cycle compared to original function. Theory analysis to the mapping is well-distributed, and self-correlation and mutual-correlation is also good property. Through encryption test, it shows that new algorithm has high security , is realized easily ,and the encryption speed is very fast.
