A proprietary algorithm developed by RSA Data Security, Inc., RC4 is a stream cipher. A stream cipher encrypts one byte at a time. The RC4 key size can range from 8 to 2048 bits. Note: The term cipher ...

Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers. Fast algorithms on quantum computers could easily break many widely used cryptosystems ...

The EIP-44 is the IP for accelerating the ARC4 stream cipher algorithm (used for legacy SSL & IPsec). Designed for fast integration, low gate count and full transforms, the EIP-44 accelerator ...

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

At a time when IT departments are scrambling to add quantum resistance to their apps, software pioneer JP Kusumi has released ...

Cryptographers constantly investigate different approaches for probing important algorithms for vulnerabilities. The two main techniques for measuring stream ciphers are linear and differential ...

These algorithms take a block of plaintext and the encryption key as input and run them through a subprocess that repeats for a set number of rounds before outputting a finished ciphertext.

Over the weekend, the GandCrab V4 Ransomware was released with numerous changes. These changes include a different encryption algorithms, a new .KRAB extension, a new ransom note name, and a new ...
