Abstract

An instant message (IM) virtual buddy is provided for communicating authentic messages to a client IM application of a client data communication device. The client IM application, using an encryption key associated with the virtual buddy, authenticates messages originating from the virtual buddy. The virtual buddy may be provisioned as a part of the IM application. The encryption key is preferably a public key of a public/private key pair in accordance with asymmetric encryption techniques. Users of client devices may receive authentic messages from the virtual buddy such as an enterprise, service or software provider and trust the source and content of the message.

Claims

1. A method comprising:

providing a instant message (IM) application for installing on a client data communication device, said IM application comprising;

an interface for sending and receiving IM communications; and

a contact for communicating IM messages with a virtual IM buddy; and

wherein said IM application is adapted to authenticate IM messages originating from said virtual IM buddy.

2. The method according to claim 1 wherein said IM application is configured to authenticate IM messages originating from said virtual IM buddy using an encryption key associated with the virtual IM buddy.

3. The method according to claim 2 wherein said IM application is configured to decrypt a portion of content of each of said IM messages originating from said virtual IM buddy using said key.

4. The method according to claim 1 comprising including an encryption key with said IM application for authenticating messages originating from said virtual IM buddy.

5. The method according to claim 1 comprising including a first virtual IM buddy message with said IM application and associated with the contact for the virtual IM buddy to provide information.

6. The method according to claim 1 comprising installing an instance of said client IM application on at least one client data communication device.

7. The method according to claim 6 comprising using the IM application installed on the client data communication device to receive and authenticate at least one IM message from the virtual IM buddy.

8. The method according to claim 7 comprising using the IM application installed on the client data communication device to send at least one IM message to the virtual IM buddy.

9. The method according to claim 7 comprising sending at least one authentic IM message originating from said virtual IM buddy to a plurality of client data communication devices each having an instance of said IM application for receiving and authenticating authentic IM messages.

10. The method according to claim 9 comprising storing at least one corresponding encryption key with which to sign authentic IM messages;

and using the at least one corresponding encryption key to sign authentic IM messages.

11. A client data communication device comprising:

a client instant message (IM) application providing an interface for sending and receiving IM communications, said IM application comprising a contact for a virtual IM buddy for receiving IM messages and said IM application adapted to authenticate IM messages originating from said virtual IM buddy.

12. The client data communication device according to claim 11 comprising an encryption key associated with said contact for use by said IM application for authenticating IM messages originating from said virtual IM buddy.

13. The client data communication device according to claim 12 wherein said IM application decrypts a portion of content of each of said IM messages originating from said virtual IM buddy using said encryption key.

14. The client data communication device according to claim 11 comprising a first virtual IM buddy message installed with said IM application and associated with said contact to provide information.

15. A computer program product providing an instant message (IM) application for a client data communications device, the computer program product comprising a computer-readable medium embodying data and instructions executable by a computer to:

(i) provide an interface with which to send and receive IM messages, said interface comprising a contact for a virtual IM buddy for communicating IM messages with said virtual IM buddy; and

(ii) authenticate IM messages originating from said virtual IM buddy.

16. The computer program product according to claim 15 wherein said instructions and data comprise an encryption key associated with said contact with which to authenticate IM messages originating from said virtual IM buddy.

17. The computer program product according to claim 15 wherein said instructions and data comprise a first virtual IM buddy message signed for installation with said IM application and associated with said contact to provide information about the IM application or the virtual IM buddy.

18. A data communication device comprising:

an IM application for conducting IM communications; and

a store of at least one encryption key with which to sign authentic IM messages for originating from a virtual IM buddy; and

wherein said IM application comprises an interface with which to sign authentic IM messages for sending to a plurality of client data communication devices adapted to receive and authenticate said authentic IM messages.
