1. A method of inhibiting a denial of service attack based on a synchronization process in a peer-to-peer network, comprising:

  • receiving a SOLICIT message at a second node, the SOLICIT message requesting cache synchronization from a first node and containing a first node peer address certificate (PAC);

    examining the first node PAC to determine its validity at the second node;

    dropping the SOLICIT message when the step of examining the first node PAC determines that the first node PAC is not valid;

    generating first connection information specifically identifying the SOLICIT message with the first node;

    maintaining the first connection information when examining the first node PAC determines that the first node PAC is valid;

    generating second connection information specifically identifying a REQUEST message with the first node; and

    comparing the first connection information and the second connection information.
