Bitcoin relies on several algorithms to secure the coin from theft. Prominent among these is the Elliptic Curve Digital Signature Algorithm (ECDSA). An ECDSA employs asymmetric encryption to generate ...

Quantum computing is moving from theory to reality faster than many people expected—and that has major implications for cryptocurrency security.

An early years Bitcoin OG is raising alarm bells over Bitcoin quantum resistance, what does it mean for Bitcoin price prediction into March?

There are two fundamentally different authentication schemes: symmetric systems, which rely on secret keys shared by host and authenticator, and asymmetric systems, such as the Elliptic Curve Digital ...

Aggregate signatures aren’t new. They’ve been around since the early 2000s. But building one that actually works in Bitcoin’s security model, with Bitcoin’s elliptic curve, has never been proven.

If you keep wiping and re-installing the operating system on IoT devices such as Raspberry Pis, SSH will get cranky because the board's public key will change Those of you new to Internet of Things ...

Digital signatures represent one of the most widely used security technologies for ensuring unforgeability and non-repudiation of digital data. The digital signature technique is generally used for ...

Oracle has patched a critical vulnerability in newer versions of Java that adversaries could exploit to forge security certificates, digital signatures, two-factor authentication messages, and ...

Meet DahLIAS, a full aggregation signature scheme that works with secp256k1, Bitcoin's cryptographic curve. Aggregate signatures aren’t new. They’ve been around since the early 2000s. But building one ...
