  • Publication number: 20210144161
    Abstract: A computing system and related method protect a computer network connection manager's resources from attempted resource attacks by extracting SrcIP and TTL values from received data packet headers. Extracted SrcIP and TTL values are analyzed to determine the probability that a received data packet is malicious. If the probability exceeds a specified threshold, resources are denied, and the packet is dropped. If the specified threshold is not exceeded, resources are allocated to the received data packet. The SrcIP reputation score, TTL value frequency, SrcIP frequency, SrcIP geo-location, and resource occupancy may all be used in computing the probability of a malicious data packet. These factors may be weighted and summed to calculate the probability of a malicious data packet.

  • Patent number: 10892892
    Abstract: A method and computer architecture for securely sharing information with an arbitrary set of users in end-to-end fashion. A secure data sharing system includes clients and servers. Client programs running on specific client computers encrypt plaintext data and cryptographically bind the decryption of the encryption key to policy information that contains rules about a permitted decryption operation access. Other clients decrypt the encrypted data shared by the original client by proving to the server their identity and in return receiving cryptographic material.

  • Patent number: 10873618
    Abstract: A method and system for generating a set of API Endpoints includes receiving network data requests to extract raw URL strings and http Methods therefrom, splitting the URL strings into component groups, and building a component tree. Dynamic components are detected and replaced with a generic designator. The component tree is then collapsed by merging identical branches into a single branch, thereby providing a set of API Endpoints. Detection of dynamic components can include determining that the number of child nodes paired with a parent node is relatively large; detecting that the number of occurrences of a parent node component is relatively high within a predetermined time in comparison to the number of occurrences of corresponding child node components; detecting a relatively high similarity of grandchild node components that share a parent node; and detecting child components having randomly generated character sequences.

  • Patent number: 6362986
    Abstract: A DC-to-DC converter generates an output voltage from an input voltage. The converter includes first and second inductive windings and a magnetic core. One end of the first winding is switched at about 180 degrees out of phase with one end of the second winding, between ground and the input voltage. The first winding is wound about the core in a first orientation, and the second winding is also wound about the core in the first orientation so as to increase coupling between windings and to reduce ripple current in the windings and other parts of the circuit. This version is a buck converter—versions that form boost, buck-boost and other converters are also provided. The invention also provides a multi-phase DC-to-DC converter for providing an output voltage from an input voltage. The converter has N (N≧2) inductive windings alternatively switched, again in the buck-converter version, between ground and the input voltage. Again, boost, buck-boost, or other versions are also provided.
