Key takeawaysButerin sees a nontrivial 20% chance that quantum computers could break current cryptography before 2030, and he argues that Ethereum should begin preparing for that possibility.A key ...

The Firefox browser will now deny TLS connections to servers using weak Diffie-Hellman keys. Logjam was one of several downgrade attacks discovered in the last 18 months that could theoretically allow ...

A strategic and technically grounded understanding of how fault injection can undermine the security of elliptic curve ...

Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a ...

On Tuesday, a team of computer scientists released a report (.PDF) documenting cryptographic problems with the Diffie-Hellman key exchange, a popular algorithm used by Internet protocols to agree on a ...

Communicating "in the clear", Alice and Bob select two numbers, q and n. Alice then selects the secret number xa. Bob selects the secret number xb. From the two public numbers, q and n, and her secret ...

One of the potential encryption algorithms that was a serious candidate to be used in the quantum computing world has been defeated worryingly simply. The algorithm in question is called SIKE ...
