Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist. Understanding Bitcoin is a one-way hash function should make sense because a hash function ...

The vulnerability in the SHA-1 one-way hash function, which recently rocked the cryptographic world, is not seen as a threat to a new generation of one-time password products based on the encryption ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...

In 1868, the mathematician Charles Dodgson (better known as Lewis Carroll) proclaimed that an encryption scheme called the Vigenère cipher was “unbreakable.” He had no proof, but he had compelling ...

What’s the best way to solve hard problems? That’s the question at the heart of a subfield of computer science called computational complexity theory. It’s a hard question to answer, but flip it ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...
