How does one design a blockchain protocol? Back in 2013, while in Athens, I set out to design a non-proof-of-work-based blockchain protocol motivated by the debt crisis in Greece, looming bank ...

Bytom, Poland July the 7 th, 2022 -- NIST, the U.S. Department of Commerce’s National Institute of Standards and Technology has just announced (July the 5 th, 2022) the first Quantum-Resistant ...

When designing cryptographic protocols and systems, many guiding principles ought to be respected. Often, these guiding principles are lessons learned from years of attacks and vulnerabilities against ...

Members can download this article in PDF format. Threats from various sources relentlessly attack all our connected systems. Connected systems don’t necessarily mean those connected to the internet.

Cryptographic algorithms lie at the heart of modern information security, and substitution box (S‐box) design is a critical component in achieving robust encryption. S‐boxes provide the nonlinearity ...

Encryption requirements are now found in almost every new SoC design. From digital rights management, through storage security and virtual private network (VPN) applications, security is becoming a ...

The method was called “indistinguishability obfuscation,” or IO. The authors touted it as a “central hub” for all of cryptography—a unified basis upon which to reconstruct familiar cryptographic tools ...

The basics of post-quantum cryptography. Why we need post-quantum cryptography (PQC). What’s being done to develop it before quantum computers arrive. The term quantum computing brings images of ...
