ASHBURN, Va. – There are three general categories of cryptographic algorithms that are common in trusted computing: secure hashing, symmetric cryptography, and asymmetric cryptography. This column ...

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 ...

Ofer A. Lidsky is an entrepreneur with over 30 years of experience and is the founder and CEO of Excellent Brain. In today’s digital age, data encryption is vital for protecting sensitive information.

Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

RC4 is a symmetric cryptosystem, invented in 1987 by MIT cryptographer Ronald Rivest, who went on to found RSA Security. The algorithm has several known flaws, but it is still widely used. RC4 is also ...

Members can download this article in PDF format. The security of cryptographic applications critically relies on symmetric keys and private keys that are continually kept secret. The method used to ...

In this paper, the authors present a peer analysis in the field of encryption algorithms, in concentrating on private key block ciphers which are generally used for bulk data and link encryption. They ...

When quantum computers become powerful enough, they could theoretically crack the encryption algorithms that keep us safe. The race is on to find new ones. Tech Review Explains: Let our writers ...
