Abstract

A method (20) of disseminating information by a first end terminal (6) in a network having a plurality of end terminals (6) is disclosed. The method (20) includes the first end terminal (6) receiving (22) information from an information source, validating (24) the information and storing (28) the validated information. The method (20) also includes automatically forwarding (34) the validated information to a second end terminal (6) of the plurality of end terminals (6) over a communication channel established between the first and the second end terminals (6). The communication channel is established for a purpose separate from forwarding said validated information.

Claims

1. A method of disseminating information by a first end terminal in a network having a plurality of end terminals, said method comprising:

receiving information from an information source;

validating said information;

storing said validated information; and

automatically forwarding said validated information to a second end terminal of said plurality of end terminals over a communication channel established between said first and said second end terminals, wherein said communication channel is established for a purpose separate from forwarding said validated information.

2. A method according to claim 1, further including receiving a positive acknowledgement from said second end terminal.

3. A method according to claim 2, further including informing said information source that said information has been successfully disseminated.

4. A method according to claim 3, further including receiving a reward for successfully disseminating said information.

5. A method according to claim 1, wherein validating said information includes validating said information using a verification key provided by a certification authority.

6. A method according to claim 5, wherein said verification key is a public key.

7. A method according to claim 1, wherein said method is performed by a validated first end terminal.

8. A method according to claim 7, wherein said first end terminal is validated using a root key.

9. A method according to claim 1, wherein said information is forwarded over said established communication channel as a piggyback in a frame.

10. A method according to claim 9, wherein said information is contained in a data field of said frame.

11. A method of disseminating information by a first end terminal in a network having a plurality of end terminals, said method comprising:

receiving information from an information source;

validating said information;

storing said-validated information;

detecting establishment of a communication channel between said first end terminal and a second end terminal of said plurality of end terminals, wherein said communication channel is established for a purpose separate from forwarding said validated information; and

automatically forwarding validated information to said second end terminal over said established communication channel.

12. A method according to claim 11, further comprising:

receiving a positive acknowledgement from said second end terminal; and

informing said information source that said information is successfully disseminated.

13. A method according to claim 12, further comprising:

receiving a reward for successfully disseminating said information.

16. A system according to claim 15, further including an information certification authority that provides a verification key to said first end terminal for validating said information.

17. A system according to claim 16, wherein said information source receives said information from said information certification authority.

14. A method of disseminating information over a network having a plurality of end terminals, said method comprising:

sending information from an information source to at least one end terminal, wherein said at least one end terminal validates said information and forwards said information via a piggyback in a frame when a channel is established between said at least one end terminal and another end terminal for a purpose other than dissemination of information.

15. A system for disseminating information comprising:

an information source; and

at least two end terminals including a first end terminal and a second end terminal;

wherein said first end terminal performs a method including;

receiving information from said information source;

validating said information;

storing said validated information; and

automatically forwarding said validated information to said second end terminal of said plurality of end terminals over a communication channel established between said first and said second end terminals, wherein said communication channel is established for a purpose separate from forwarding said validated information.
