The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

In July, the National Institute of Standards and Technologies selected four cryptography algorithms as national standards for public key security in order to prepare for an era of quantum computers, ...

Before we take a look at the available security IP out there, a few definitions are in order: Cipher: This is the algorithm for encrypting and decrypting data. Ciphers rely on symmetric or asymmetric ...

The Data Encryption Standard (DES) is defined in FIPS PUB 46-3 as a symmetric-key algorithm. The triple DES (TDES) is a block cipher that applies the ...

The key used for these kinds of symmetric encryption is called as File Encryption Key (or FEK). This FEK is in return encrypted with a public or a private key algorithm like RSA and stored with the ...
