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.

A group of researchers from Princeton University, Stanford University and the City University of New York, have announced a new ECDSA threshold signature scheme that is particularly well-suited for ...

Once quantum computers mature, they could crack Bitcoin’s ECDSA signatures, threatening over $1 trillion in value. Both require disruptive solutions, hard forks or complex hybrid signatures, to become ...

Java versions 15, 16, 17, and 18 (and maybe some older versions) have a big problem, ECDSA signature verification is totally broken. The story is a prime example of the dangers of unintended ...

Organizations using newer versions of Oracle’s Java framework woke up on Wednesday to a disquieting advisory: A critical vulnerability can make it easy for adversaries to forge TLS certificates and ...

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 ...

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 ...
