Abstract:

Asynchrony of short messages(SMS) brings inconvenience to the key distribution. We propose an SMS encryption system based on the dynamic key. The dynamic encryption key increases difficulty in cryptanalysis. The dynamic authentication key resists the replay attack. The scheme uses only hash function and symmetric encryption which are more suitable to the resource-limited mobile system. Experimental results on Android platform show good realization performance of the scheme.

Key words: SMS encryption, dynamic key, key distribution, Android platform
