Latest Patents

Sundahl holds a patent for a "Randomized canary and shadow stack for JIT-ROP defense." This invention improves systems and methods of providing computer security by protecting control data, such as return addresses, from being disclosed or modified. The technology enhances the traditional stack canary with randomization to prevent brute-force attacks and information leakage. Additionally, it employs a shadow stack that conceals the return address, encodes it in memory, and replaces the real return address with a substitute value. This innovative approach effectively detects and prevents manipulation of the return address, thereby enhancing the security of computing systems against stack smashing, ROP attacks, and JIT-ROP attacks.
