Abstract: Systems and methods are provided for establishing a secure communication link between a first client and a second client. One exemplary computer-implemented method for establishing a secure communication link between a first client and a second client includes accessing, from a storage, identification information of a user of the first client. The method further includes receiving a Domain Name Service (DNS) request from the first client requesting a secure network address corresponding to a secure domain name associated with the second client. The method further includes authenticating the user based on the user identification information. The method also includes transmitting the secure computer network address in response to the DNS request based on a determination that the user has been authenticated. A secure communication link between the first client and the second client is established based on the secure computer network address.

Abstract: A method of establishing a secure communication link includes receiving, at a domain name server (DNS), a request to communicate securely, the request including an identifier of a client device and having been sent in response to a determination that a DNS request from the client device corresponds to a first computer configured to communicate securely. The method includes sending a second request to a server computer. In response to second request, the server computer compares the received client device identifier to one or more stored client device identifiers to determine a security level of the client device and determines a security level of the first computer. The sever computer determines, based on a comparison of the security level of the client device and the security level of the first computer, whether the client device is authorized to communicate with the first computer, and generates a resource used to establish the secure communication link between the client device and the first computer.

Abstract: A modular electrical connector with modular components suitable for assembly into a right angle connector may also be used in forming an orthogonal connector or connector in other desired configurations. The connector modules may be configured through the user of extender modules. Those connector modules may be held together as a right angle connector with a front housing portion, which, in some embodiments, may be shaped differently depending on whether the connector modules are used to form a right angle connector or an orthogonal connector. When designed to form an orthogonal connector, the extender modules may interlock into subarrays, which may be held to other connector components through the use of an extender shell. The mating contact portions on the extender modules may be such that a right angle connector, similarly made with connector modules, may directly mate with the orthogonal connector.

Abstract: A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.

Abstract: A cable termination that provides low signal distortion even at high frequencies. Conductive elements of the cable are fused to edges of signal conductors in a cable connector or other component terminating the cable. For terminating a differential pair, the conductive elements of the cable may be terminated to opposing edges of a pair of signal conductors in the cable termination. The conductive elements may be shaped such that the spacing between signal paths passing through the conductive elements of the cable and into the signal conductors of the cable termination is uniform.

Abstract: An electrical connector designed for high speed signals. The connector includes one or more features that, when used alone or in combination, extend performance to higher speeds. These features may include compensation for tie bars that are used to hold conductive members in place for molding a housing around the conductive members. Removal of the tie bars during manufacture of the connector may leave artifacts in the conductive members and/or housing, which may be addressed by the features. The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed. Alternatively or additionally, a housing may include openings around tie bar locations such that a punch may be used to sever the tie bars. These openings may be filled to avoid performance-affecting artifacts.

The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed.

Abstract: A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion and edge coupled end portions. Broadside coupling provides balanced pairs for very high frequency operation, while edge coupling provides a high density interconnection system at low cost.
