Why isn't black_box a guarantee? We examine the principles and limits of the optimization barriers that protect constant-time code, and the compiler-level response that has since emerged.

A memory access the compiler can't erase, merge, or reorder. We take a deep look at Rust's volatile semantics, from hardware control to security applications.

Independent researcher Giancarlo Lelli has been awarded 1 BTC by Project Eleven for breaking a 15-bit ECC key on a publicly accessible cloud quantum computer. We examine what this means cryptographically, and the real threat horizon drawn by the latest research from Caltech and Google.

From the basics of bit operations to their practical applications in information security, we explore how low-level operations form the foundation of security systems.

Learn what constant-time operations are, why they matter, and how to implement them.

An introduction to the fundamentals of quantum information science theory and accessible methods for understanding it.

A brief summary of quantum information science theory and how these concepts can be applied to classical information security systems.
