Sergei Silvestrov RSA algorithm webpage

This RSA algorithm webpage was initiated after the last lecture in the
Algebra course given by me in
the Centre for Mathematical Sciences, Engeneering Faculty (LTH) , Lund University.

More staff on RSA algorithm is added continuously. So bookmark, link and visit this page often!

Contact  me for any ideas and cooperation or joint project proposals on RSA or other cryptography related topics

Extract from the English Wikipedia article on RSA:
In cryptography, RSA (which stands for Rivest, Shamir and Adleman who first publicly described it) is an algorithm for public-key cryptography. It is the first algorithm known to be suitable for signing as well as encryption, and was one of the first great advances in public key cryptography. RSA is widely used in electronic commerce protocols, and is believed to be secure given sufficiently long keys and the use of up-to-date implementations.  ..........
