Patent ID: 8924706

Claim:
A method of establishing and conducting secure short message communications between plural peer devices, comprising: (a) transmitting cryptographic information to a peer device over an electronic connection; (b) securely providing, to each of the plural peer devices, a one time pad using a communication that is out of band with respect to the electronic connection including not conveying the one time pad over the electronic connection but instead using a different communications path that prevents interception of the one time pad by eavesdroppers on the electronic connection, the one time pad comprising a one time passcode or passphrase for input into each of the plural peer devices; (c) using the one time pad to authenticate the transmitted cryptographic information and/or as a seed to cipher the cryptographic information for transmission; (d) generating a shared secret from the cryptographic information; and (e) using the shared secret to securely protect short messages for exchange between the plural peer devices over the same or different electronic connection.
