    Abstract: A security infrastructure and methods are presented that inhibit the ability of a malicious node from disrupting the normal operations of a peer-to-peer network. The methods of the invention allow both secure and insecure identities to be used by nodes by making them self-verifying. When necessary or opportunistic, ID ownership is validated by piggybacking the validation on existing messages. The probability of connecting initially to a malicious node is reduced by randomly selecting to which node to connect. Further, information from malicious nodes is identified and can be disregarded by maintaining information about prior communications that will require a future response. Denial of service attacks are inhibited by allowing the node to disregard requests when its resource utilization exceeds a predetermined limit. The ability for a malicious node to remove a valid node is reduced by requiring that revocation certificates be signed by the node to be removed.

    Abstract: A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.

    Abstract: Disclosed is a system for organizing and storing information about multiple peer identities. New certificates are introduced that enable a user to efficiently create, modify, and delete identities and groups. New storage structures enable the user to list and search through existing identities, groups, and their related certificates. An identity certificate contains information about a peer identity. A group root certificate is created by a user when he decides to create a new group. When the group creator user wishes to invite another entity to join the group, it creates another type of certificate called a group membership certificate. The group membership certificate is logically “chained” to the group root certificate. The invitee checks the validity of these certificates by checking that the chaining has been properly done. The invitee may then be allowed to invite other entities to join the group by sending out its own group membership certificates.

    Abstract: An integrated circuit (IC) includes a first I/O cell, a logic cell, a trigger signal generation circuit, and a second I/O cell having a voltage selection pin. I/O interfaces of the first I/O cell receive first and second supply voltages, respectively, and I/O interfaces of the second I/O cell receive third and fourth supply voltages, respectively. The first I/O cell generates a first trigger signal when the first supply voltage reaches a first predetermined voltage. The logic cell receives the first trigger signal and generates a safe-state signal. The trigger signal generation circuit generates a second trigger signal when the third supply voltage reaches a second predetermined voltage. The voltage selection pin receives the safe-state signal and the second trigger signal and sets the second I/O cell in a safe-state mode, which protects the second I/O cell from over voltage damage.
