You might be tempted to use that shiny new prime number for RSA encryption. Don't do it. RSA encryption uses the difficulty of factoring the product of two large prime numbers to make sure hackers can ...

Prime numbers are all the rage these days. I can tell something’s up when random people start asking me about the randomness of primes—without even knowing that I’m a mathematician! In the past couple ...

RSA encryption is a major foundation of digital security and is one of the most commonly used forms of encryption, and yet it operates on a brilliantly simple premise: it's easy to multiply two large ...

When sending your credit card number through a public medium, such as the Internet, your financial credibility may be compromised if the number is not first encrypted. It is impossible to tell who may ...

Researchers are closing in on deciphering 1,024-bit RSA encryption, security industry watchers said following an unprecedented numbers-cracking feat by a group of French, German, and Japanese ...

Every time you pay online, your data is protected by a maths problem nobody has proved is unbreakable. Here is what that ...

A large chunk of the global economy now rests on public key cryptography. We generally agree that with long enough keys, it is infeasible to crack things encoded that way. Until such time as it isn’t, ...

In contrast to the cooperative preparations required for setting up private key encryption, such as secret-sharing and close coordination between sender and receiver ...
