  Improving the Security of Time-Bounded Mission-Critical K-Variant Systems by Inserting Unreachable Code
  Author(s): Berk Bekiroglu* and Bogdan Korel
  
  K-variant is a multiple variant architecture designed to enhance the security of time-constrained systems, particularly against memory exploitation attacks. In a K-variant system, variants are generated through controlled source code program transformations. Inserting unreachable code is one of the program transformations used to generate new variants in K-variant systems. It is possible to generate functionally equivalent programs by inserting random unreachable code. Because critical instructions in memory are shifted by inserting unreachable code, the survivability of K-variant systems can be improved against memory exploitation attacks. The purpose of this study is to determine the effectiveness of inserting unreachable code in enhancing the security of time-bounded K-variant systems against memory exploitation attacks. The effect of inserting unreachable code on the survivability.. View More»
