Safety and Security Framework for Exception Handling in Concurrent Programming

Exception handling mechanism provides a structured way of handling errors in software applications as compared to traditional error handling. Moreover it may cause safety and security threats if not used carefully. Some of the possible issues are information leakage, spoofed parent classes and inconsistent states. Unfortunately most programmers are rarely aware of exception handling re-percussions, in case of inappropriate exception handling. However, with the advent of multi-core processors people are more interested in utilizing all the computational powers of machine by using concurrent programming. This also brings up new challenges in terms of exception handling decisions like retry, continuation, rollback, termination and at the same time maintaining the clean state of the program. In this paper we propose a safety and security architecture by using Aspect Oriented Programming (AOP) technique and transactional memory (TM) concept without making any modifications to the development language.
