The field of error correction and security is rapidly evolving, with a focus on developing innovative solutions to protect against increasingly sophisticated threats. Recent research has explored the use of 3D integration and dynamic activity patterns to conceal critical activities and reduce side-channel vulnerabilities. Additionally, there has been a push towards developing more efficient and effective fault detection methods, such as recomputation-based fault detection and memory rule checkers. Furthermore, researchers have been investigating new decoding algorithms for various types of codes, including twisted generalized Reed-Solomon codes and non-binary LDPC codes. Noteworthy papers in this area include the proposal of a novel approach to proactively conceal critical activities in 3D integrated circuits, and the development of a lightweight and efficient fault detection module for Number Theoretic Transform. The paper on FlashVault, an in-NAND self-encryption architecture, is also particularly noteworthy for its ability to support multiple cryptographic algorithms without incurring area overhead. Overall, these advances have the potential to significantly improve the security and reliability of various systems and applications.
