Secure Peer-to-Peer Messaging Invitation Architecture

A method performed by a second communication device comprising:

• receiving an invitation to engage in peer-to-peer messaging from a first communication device, the invitation comprising an encrypted first personal identification number unique to the first communication device, the first personal identification number having been encrypted using a public key of the second communication device and utilized by a peer-to-peer messaging system to exchange messages using a peer-to-peer messaging application;
• preparing an acceptance message, the acceptance message including an encrypted second personal identification number unique to the second communication device, the second personal identification number being encrypted by the second communication device using a public key of the first communication device;
• sending the acceptance message to the first communication device using a communication application different from the peer-to-peer messaging application;
• decrypting the encrypted first personal identification number using a private key corresponding to the public key of the second communication device;
• and
• performing at least one of receiving a first peer-to-peer message from the first communication device, the first peer-to-peer message having been sent using the second personal identification number, and sending a second peer-to-peer message to the first communication device using the first personal identification number.

A computer readable medium comprising computer executable instructions to be performed by a first communication device, the computer executable instructions comprising instructions for:

• preparing an invitation to engage in peer-to-peer messaging for a second communication device, the invitation comprising an encrypted first personal identification number unique to the first communication device, the first personal identification number being encrypted using a public key of the second communication device and utilized by a peer-to-peer messaging system to exchange messages using a peer-to-peer messaging application;
• sending the invitation to the second communication device using a communication application different from the peer-to-peer messaging application;
• receiving from the second communication device, an acceptance message, the acceptance message including an encrypted second personal identification number unique to the second communication device, the second personal identification number having been encrypted by the second communication device using a public key of the first communication device;
• decrypting the encrypted second personal identification number using a private key corresponding to the public key of the first communication device;
• and
• performing at least one of sending a first peer-to-peer message to the second communication device using the second personal identification number, and receiving a second peer-to-peer message from the second communication device, the second peer-to-peer message having been sent using the first personal identification number.

A first communication device having a first personal identification number and configured to communicate with a second communication device having a second personal identification number different from the first personal identification number, the first communication device comprising:

• a processor;
• a memory;
• a communication application;
• and
• a peer-to-peer messaging application different from the communication application that is stored in the memory and executable by the processor to:
• prepare an invitation to engage in peer-to-peer messaging for a second communication device, the invitation comprising an encrypted first personal identification number unique to the first communication device, the first personal identification number being encrypted using a public key of the second communication device and utilized by a peer-to-peer messaging system to exchange messages using a peer-to-peer messaging application;
• send the invitation to the second communication device using a communication application different from the peer-to-peer messaging application;
• receive from the second communication device, an acceptance message, the acceptance message including an encrypted second personal identification number unique to the second communication device, the second personal identification number having been encrypted by the second communication device using a public key of the first communication device;
• decrypt the encrypted second personal identification number using a private key corresponding to the public key of the first communication device;
• and
• perform at least one of sending a first peer-to-peer message to the second communication device using the second personal identification number, and receiving a second peer-to-peer message from the second communication device, the second peer-to-peer message having been sent using the first personal identification number.
