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 ...

In today's electronic age, the importance of digitalcryptography in securing electronic data transactions isunquestionable. Every day, users electronically generate andcommunicate a large volume of ...

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 ...

Symmetric encryption uses one secret key for both encryption and decryption (for example, AES or ChaCha20 ciphers). Symmetric algorithms are fast and well-understood, and the good news is that ...

Many embedded systems depend on obscurity to achieve security. We often design systems to download unsigned or unencrypted firmware upgrades or store unencrypted user data, a practice we justify ...

SSL (Secure Sockets Layer) is currently the most widely deployed security protocol. It is the security protocol behind secure HTTP (HTTPS), and thus is responsible for the little lock in the corner of ...

Castle Shield has integrated two of the NIST Round 3 finalists PQC asymmetric encryption. NIST will select a small subset of these algorithms that will form the core of the first post-quantum ...

Threats to computer and network security increase with each passing day and come from a growing number of sources. No computer or network is immune from attack. A recent concern is the susceptibility ...
