Karsten Nohl, the founder of Berlin's Security Research Labs, has announced an exploit for SIM cards using the outdated 56-bit DES algorithm for its signature verification. The security researcher ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

Researchers have solved one aspect of the discrete logarithm problem. This is considered to be one of the 'holy grails' of algorithmic number theory, on which the security of many cryptographic ...

Cryptographic algorithms can be roughly classified in two categories: Encryption algorithms transform an input file into an output file from which it is (quite) impossible to recover the original ...
