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.
Un système et des méthodes permettant une messagerie immédiate poste-à -poste entre des dispositifs mobiles (10) dans un système sans fil. La présente invention porte sur une architecture d'invitation qui permet l'échange de numéros d'identification personnels (NIP) sans qu'un utilisateur ne doive accéder à son NIP ni fournir celui-ci. Une application de messagerie (160) chiffre son NIP connexe avant de le fournir à une application de messagerie (160) sur un autre dispositif mobile (10) au moyen d'une application de communication existante (162). L'architecture d'invitation gère automatiquement le chiffrement, les échanges de clés requis, la composition de l'invitation et les messages d'acceptation, et le déchiffrement et le stockage des NIP.
