Abstract

A convenient, easy to use ubiquitous secure communications capability can automatically encrypt and decrypt messages without requiring any special intermediating security component such as gateways, proxy servers or the like. Trusted/secure applications for the mobile workforce can significantly improve productivity and effectiveness while enhancing personal and organizational security and safety.

Claims

1. A method of providing secure communications between end-user devices comprising:

communicating a message between a first device and a second device, said message providing an indication that the first device wishes to send a secure message to the second device;

enable downloading on demand of an application to the second device permitting the second device to decrypt a secure message sent by the first device;

agreeing upon, between the second device and the first device, at least one shared secret based on a handshake communication between the first and second devices; and

communicating, between the first device and the second device, an encrypted message that can be decrypted using said shared secret.

2. The method of claim 1 wherein said message comprises an SMS message.

3. The method of claim 1 further including encrypting, at the first device, an SMS message for decryption by the second device.
