Abstract: The present invention provides systems and methods that utilize inductive current steering to improve logic circuit performance by mitigating propagation delays associated with conventional transistor current steering. The system and methods employ RF transformers, wherein energizing primary windings induce current in associated secondary windings. In one aspect, a single clock bus is employed to induce the current, which is routed via respective ends of the secondary winding to emitter leads of the transistors. This current and voltage is 180 degrees out-of-phase such that one transistor is “on” while the other is “off,” which generates a differential output. In another aspect, a differential clock signal is employed to induce the current in secondary windings and associated transistor emitters.
Abstract: System and method for secure legacy enclaves in a Public Key Infrastructure that includes one or more legacy servers, client platforms, directories, and a Virtual Private Network extranet gateway. The servers contain one or more legacy applications and are connected to a first network. The client plafforms are connected to a second network and contain legacy software employable by users to access the legacy applications. The directories are connected to the second network and contain information on user authorization to access the servers. The gateway is connected between the servers and the second network. The gateway requests a signature certificate of each user attempting access to a legacy application; queries the directory to confirm the user is allowed access to the server after authenticating the user; and establishes a connection between the legacy software and the legacy application if the user is allowed access to the server.
