摘要
The present disclosure introduces simple methods and systems for personal encryption of messages and data, using a GSM handset. The proposed methods and systems furnish another layer of communication security instead of or in addition to that of the carrier. Users can generate and customize their own encrypted communication, independent of the carrier. In one embodiment the existing handset hardware can be used to implement the personal encryption, without the need for additional hardware. The present disclosure also provides methods and systems for generating different encryption keys and synchronization methods. In one exemplary system the encryption key is kept in the memory of the handset, while in another exemplary system the key is downloaded from an SMS (Short Message Service) station. In one exemplary method the encryption key sequence is as long as the block data and is synchronized with each block data, while in another exemplary method the transmitted information is segmented and flagged for synchronization with the encryption key.
