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 ...
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 ...
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 ...

Why Vitalik believes quantum computing could break Ethereum’s cryptography sooner than expected
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 ...
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 ...
