Randomized C/C++ dynamic memory allocator

Published 24 Aug 2021 in cs.DS, cs.CR, and cs.PF | (2108.10779v1)

Abstract: Dynamic memory management requires special attention in programming. It should be fast and secure at the same time. This paper proposes a new randomized dynamic memory management algorithm designed to meet these requirements. Randomization is a key feature intended to protect applications from "use-after-free" or similar attacks. At the same time, the state in the algorithm consists only of one pointer, so it does not consume extra memory for itself. However, our algorithm is not a universal solution. It does not solve the memory fragmentation problem and it needs further development and testing.
