  • Certificate enrollment with purchase to limit sybil attacks in peer-to-peer network
    Patent number: 8301880
    Abstract: A system may protect against Sybil attacks on a peer-to-peer (P2P) network based on each one the nodes in the P2P network being identified by a corresponding certificate. In particular, a node may receive a license key, where the license key is evidence of a purchased product license. The node may transmit a message included in the license key to a certificate authority. The node may receive a certificate from the certificate authority in response to authentication of the message. The node may be identified in the P2P network with a node identifier included in the certificate.
    Type: Grant

  • Feature based configuration profiles and alarm provisioning for SONET networks
    Patent number: 7016312
    Abstract: A system for defining configuration profiles for logical entities representing features of elements in a communications network is described. Network elements or features of network elements in a communications system are represented as logical entities. Characteristics associated with the logical entities are defined. Each characteristic may have several possible values. One or more profiles are defined for each logical entity. Each profile specifies a particular value for each characteristic of the logical entity. All of the network elements can be assigned the same profile or different profiles. Two different instances of the same entity can be provisioned with two different profiles. In one embodiment, profiles are defined for failure conditions that can cause the generation of alarm signals. A set of generic profiles that defines the manner in which failures are to be reported is assigned to each specified type of failure.
