    The most significant potential source of insecurities in Ada arises from errors in Ada compilers. Several potential sources of insecurity in the language have been identified, and steps should be taken to avoid these issues. The Ada evaluation service can be used to check many potential problems with an Ada system. Other such tools are being developed.<<ETX>> View full abstract»

    Presents some of the requirements of safety critical or high reliability software used in space applications. That is in short programs whose malfunction could lead to loss of life. No such software has been produced yet, hence so far no standards have been formally established. Drafts or projects exist, and the paper presents the most likely development.<<ETX>> View full abstract»

    The technique of static analysis has, for some time now, been recognised as a technique necessary for the verification of critical software. Typically static analysis is performed by the use of automatic tools. One such tool, widely used for the verification of safety critical software, particularly in the fields of military avionics and nuclear power, is MALPAS. The advantages of this particular ...

    SPARK is an annotated subset of Ada for high-integrity programming. This subset, in conjunction with its system of annotations (formal comments), is designed to eliminate language ambiguities and insecurities, and to allow rigorous static code analysis and formal verification of programs. The development, flow analysis and correctness proof of SPARK programs is supported by a software tool, the SP... View full abstract»

    Low-Ada combines the use of Ada with the method of low-level code review. The author discusses the properties which result from this combination. He describes: unassigned value access; types with discriminants; storage allocation and testing.<<ETX>> View full abstract»
