摘要:
The secure trust relationship between communicating programs is established at any policy defined level down to individual program instances. Policy enforcement modules installed on host computer systems support qualified encrypted communications channels between discretely selected program instances. Program instances are qualified to establish communication channels, each defined by a unique session encryption key, based on an evaluation of security data including the individual process execution contexts, user authorizations, and access attributes of the program instances. A security appliance server performs the policy-based qualification based on a mutually interdependent evaluation of the security data for both the communications channel source and target program instances.
摘要:
A security server qualifies the execution of programs for networked host computer systems using a database storing pre-qualified program signatures and defined policy rules associating execution permission qualifiers with execution control values. The server executes a control program in response to execution requests received via a communications network interface from identifiable hosts, wherein a predetermined execution request received from a predetermined host computer system includes an identification of a program load request, request context related data, and a secure program signature. The control program determines an execution control value based on an evaluation of the execution request relative to the pre-qualified program signatures and defined policy rules. The execution control value is then returned to the predetermined host computer system to securely qualify the execution of the program identified from the program load request.

摘要:
A composite material having utility as an anode for lithium ion batteries comprises silicon, a transition metal, a ceramic and an electrically conductive diluent such as carbon. In particular instances, the ceramic is electrically conductive, and may comprise vanadium carbide or tungsten carbide. The transition metal may, in some instances, comprise iron. The material may be fabricated by grinding together a starting mixture of the components, and grinding may be accomplished in a high impact ball milling process, and the grinding step may cause partial alloying of the silicon with the metal and/or carbon. Further disclosed is a method for making the material as well as electrodes which incorporate the material.
