A scheme for providing data confidentiality service on top of transmission control protocol/internet protocol (TCP/IP) is proposed for connection-oriented message transmission. A novel security service architecture consisting of interactive application program, client/server, and security service modules is presented to provide the data confidentiality service. Also, the functional mechanism of the proposed scheme is given. W. Diffie and M. Hellman's (1976) key distribution method is used for session key generation and distribution.< >

The operators of DBMSs (database management systems) at battlefield command centers in military reserve units are initially novice and then occasional users. Failure modes in using these systems are analyzed in terms of human factors. Using theories of human behavior in interactive systems, guidelines for dialog design are introduced. The guidelines were applied to the design of a utility package to be used by programmers of DBMSs for occasional users.

The author suggests a method for managing and maintaining the basic software in a network from a central installation, thus offering great saving of effort, with nearly no degradation in the service level. The method is based on a small number of model systems (software), which are installed at the central installation. Each remote installation is associated with a specific model system and is called a target system. Any maintenance operation which is required by one of the target systems is applied in the model system, tested there, and eventually exported to all target systems, rather than reinstalled in each installation. Adding a junction to the network requires almost no additional work.

An approach based on the object-oriented paradigm is presented. Its major characteristics are an extended object-oriented model of computation, communication and structure, linguistic support for distributed programming, and tool support for application development. The approach is based on existing facilities from the areas of distributed object-oriented systems, remote procedure call, and object-oriented development methods. A discussion is presented of advanced issues and requirements resulting from specific problems of distribution. Examples are dependability support, heterogeneity, multiparadigm approaches, and softwareengineering data management.

The authors present a logic programming language that was used as a softwareengineering tool to design, develop and prototype the entire programming environment which supports it. The extended Prolog language, called Alpes-Prolog, has been used the basic support to develop and implement the architecture of an Advanced Logic Programming Environment (Alpes) in the context of Esprit Project 973.

A description is presented of CRUISE, the graphic user interface of OBSERV. OBSERV is a methodology that allows a rapid construction of an executable specification (or prototype) to support testing of the prototype by simulation, to facilitate smooth transition to a target system, and to provide means for reusing specification, design and code. CRUISE provides OBSERV with graphic editing capabilities that replace the existing text editor. While developing CRUISE, emphasis was placed on two distinct, yet interrelated, sets of goals. One is to develop a 'good' user-interface, whereas the other conforms to the basic concept of OBSERV--the underlying methodology. The objective set for CRUISE are outlined, and structure presented along with implementation details;future trends are discussed.

A digital consulting methodology for information technology planning is presented. The approach provides improved communications across organizational boundaries throughout the enterprise, resulting in greater management involvement and a clearer understanding of business directions, generating the information technology architecture as well as specific applications requirements. The architecture is developed by studying the business objectives and their supporting processes to derive the underlying information flows and systems. Five key factors are considered in these analyses: The business goals, the organizational culture, the personnel, the measurements, and the tools that help the enterprise achieve its goals.

A discussion is presented of the different standpoints which, at the beginning of the eighties, have brought forth prototyping as a strategy. The different lines of development are sketched, and the various trends are examined. An examination is made of the following topics: (1) the history of prototyping and the software crises, (2) prototyping terminology, (3) trends that have supported prototyping, (4) methods in line with the idea of prototyping, (5) areas of research and development that will help to promote and develop prototyping, and (6) integrating prototyping into the concept of evolutionary systems development.

The methodology of system integration that was applied in the development of the avionics system of the T/D aircraft is described. This methodology is part of the entire-life-cycle methodology. The integration methodology uses the executable system description that evolves during the system development both for test preparation and test execution. The method is equivalent to rapid prototyping.

Abstraction of smaller design tasks into hierarchies is the accepted solution to the problem of having to deal with the enormous amount of detail that arises in software design. Unfortunately, the practice of abstracting the semantics of the problem being addressed out of the data processed leads to dependencies that cannot be expressed in relation to that problem and consequently are not easily understood by the human mind. A use of abstraction techniques that will minimize the number of dependencies, and thus significantly reduce the complexity of the programming task, is suggested. In addition, a system architecture is proposed that permits direct execution of the resulting programs and exhibits properties that are very desirable for real-time, reliable systems.
