Currently smart phones can not guarantee the comprehensive security of short message service (SMS). In this study, a mobile classification security method for SMS based on Android system is proposed. We use sequence encryption with low computational complexity to encrypt short messages of minor importance and sequence encryption based on RSA digital signature to short messages related to business information. For short messages containing account numbers or passwords, we use RSA encryption to encrypt them. The applications show that proportion of 0 or 1 in cipher text encrypted by this mobile classification security method is 0.5. This method has stable performance. The mobile classification security method is applicable to resource-constrained mobile phones and other mobile devices.
