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 ...

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Device security requires designers to secure their algorithms, not only against direct attacks on the input and output, but also against side-channel attacks. This requirement is especially notable ...

The National Institute of Standards and Technology (NIST) is proposing that the Data Encryption Standard (DES), a popular encryption algorithm, lose its certification for use in software products sold ...

For more than 40 years, we have been building the modern internet on foundations that were never designed for the world we live in today. When the architects of the early internet created its ...

Over the past several years, there has been a steady drumbeat of warnings about the impact of quantum computing on traditional encryption methods, with consistent calls for organizations – both within ...

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 ...
