The RSA algorithm is a feast of genius that combines theoretical math and practical coding into working asymmetric cryptography. Here’s how it works.

With cryptographic blocks integrated into MCUs, it has become possible for developers to secure every communications channel, including interfaces such as UART that provide no security themselves.

This is the algorithm that the NSA reportedly paid RSA $10 million in exchange for making it the default way for its BSAFE crypto toolkit to generated random numbers. So how is that possible?

The RSA algorithm is but one of many systems where a set of mathematical theorems, often from number theory, can be synthesised to construct an encryption scheme.

Don't know if you've heard, but there's a new largest known prime number in town. On 26 December, mathematicians scored a late Christmas present when a computer owned by a 51-year-old engineer in the ...
