Authentication of Internet-Based Distributed Computing Resources in Chemistry

Abstract

The evolution of the World Wide Web from a model allowing only the public and open exchange of information on the global Internet via simple HTML-based pages to one involving the additional development of Intranets or Extranets with secure interactive client-server processes is discussed. These client-server processes can be customized on the client browser by the use of embedded applications such as Java Applets that allow the client to communicate with other remote applications or databases via a distributed computing architecture. We show 1 how software authentication using digital object signing procedures in conjunction with X.509 certificates was used to develop three authenticated distributed chemical applications. COS (Chemical Object Store) is a database application based on Java Remote Method Invocation, MoldaNet invokes Java3D to create a molecular visualization tool, and JSpec delivers analytical spectral data. We argue that such authentication of chemical resources on the Internet provides one mechanism for increasing the perception of quality and integrity of molecular information disseminated within the chemical community and creates an architecture for electronic commerce to develop in the molecular science community.
