Secure peer-to-peer messaging invitation architecture

摘要

A system and methods providing immediate peer-to-peer messaging between mobile devices (10) in a wireless system. An invitation architecture is disclosed which enables the exchange of personal identification numbers (PINs) without requiring a user to directly access or provide his or her PIN. A messaging application (160) encrypts its associated PIN before providing it to a messaging application (160) on another mobile device (10) through an existing communication application (162). The invitation architecture automatically manages the encryption, any requisite key exchanges, the composition of invitation and acceptance messages, and the decryption and storage of PINs.
