A novel algorithm to protect and manage memory locations
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 3
Abstract
Abstract: Most of security vulnerabilities continue to be caused by memory errors, and long-running programsthat interact with untrusted components. While comprehensive solutions have been developed to handle memoryerrors, these solutions suffer from one or more of the following problems: high overheads, incompatibility, andchanges to the memory model. Address space randomization is a technique that avoids these drawbacks, but donot offer a level of protection. To overcome these limitations, we develop a new approach in this paper thatsupports comprehensive randomization, whereby the absolute locations of all (code and data) objects, as well astheir relative distances are randomized. In particular, we have successfully deployed precise method in theimplementation of a language run-time system. Our approach is implemented as a fully automatic source-tosourcetransformation, the address-space randomizations take place at load-time or runtime, so the same copyof the binaries can be distributed to everyone - this ensures compatibility with today's software distributionmodel.
