Cryptography is one area of information security that is well known but often not well understood. The basics of the algorithms may stay the same, but as attacks and infections evolve, so too must the ...

Asymmetric-key algorithms are generally slower than symmetric-key algorithms and are used in cases where only a single operation of the algorithm is required, such as the generation of a digital ...

Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and ...

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 ...

High-profile data losses and regulatory compliance requirements have caused a dramatic increase in the use of encryption to protect data in the enterprise. Encryption is the process of applying ...

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 ...
