  • Patent number: 10681007
    Abstract: Fast string search and matching is critical for many security tasks in particular if these have “gate functionality” for instance as found in access control applications, firewalls, routers, and load balancers. The fast matching of strings is essential to impose and enforce access control policies without creating bottlenecks. Firewalls protect networks by monitoring the traffic crossing the network perimeter. The number of packet matching rules firewalls can effectively handle is limited by the matching time and space complexity of the algorithms employed. A new approach implements matching independent of the number of rules and linear in the length of the rule to be matched. A data structure used in this approach is referred to as a “Bipartite Concatenated Representation” (BCR). The space complexity of the BCR within this application scenario scales as O(N log2 N) where N is the number of rules.

  • Publication number: 20180032740
    Abstract: An approach to generating and regenerating a profile value from features of a system (e.g., a computer system), allows for certain changes of features of the system over time. The system may correspond to a client computer or a particular component of the client computer or a user of a client computer, and may also correspond to a combination of the user (i.e., a biometric characterization of the user) and the client computer or a component of the computer. The profile value may be used, for example, for purposes including identification, authentication, key generation, and other cryptographic functions involving the system.

  • Patent number: 9361621
    Abstract: A system and method are disclosed that separate control functionality from the management functionality for conducting electronic transactions. The control functions are performed by a third party resulting in a low overhead since significant overhead is incurred in response to an anomalous event, thus facilitating high throughput electronic transactions when anomalous events are infrequent. Further, the third party does not need to have access to confidential information since it only controls by observing, validating and certifying the observed communications in a specified manner to prevent confidential information from leaving the context of the transaction. Management of the transactions based on consideration of substantive information is provided by the participants.

  • Patent number: 8918849
    Abstract: In some embodiments, a user has use a single universal text—or image-based secret for generating a service-provider specific identity credential, for example username plus password, for authentication is derived. A human (i.e., the user) must interpret an image to enter this universal text (or image) based secret. For example, an image based challenge is presented to the user, and a credential is obtained based on the user's response to the challenge.
