Technology	Unencrypted SMS messages will be overheard or intercepted during transmission, so encryption is very important for mobile messages. Some encryption methods that need to share public key in advance are quite troublesome. City University researchers provide a useful alternative; the end-to-end encryption provided by their SMS system does not need to set up a pre shared key and public key certificate. Users using this identity based secure SMS system will get a user private key, which is connected to the user's unique identity, such as the user's mobile phone number.
Advantages	User friendly interface and high cost efficiency The stored message is encrypted until it is decrypted by the receiver Neither the sender nor the receiver need access to a third party for authorization
Possible applications	Financial and public institutions can use the system to encrypt messages
