An encryption method that works with continuous streams of input rather than fixed blocks. Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an ...

Abstract: Lightweight ciphers are defined as symmetric ciphers. They could be categorized into stream and block ciphers. A stream cipher is faster and less complex than block ciphers so it is suitable ...

Fixed 16-byte block processing Custom 0x81 padding mechanism Key-based byte swapping Separate encryption/decryption paths ...

Abstract: In recent years, a variety of encryption algorithms have been investigated to image cryptosystems. Most of them are based on permutation and diffusion architecture. These two procedures are ...

Such high-speed features of VSC come from full-scalable encryption algorithm as described as follows. VECTOR STREAM CIPHER AS FULL-SCALABLE CHAOTIC ENCRYPTION Our VSC is a kind of stream cipher. Thus, ...

A complete implementation of the ChaCha20 stream cipher according to RFC 8439 specifications, developed for cryptographic analysis and educational purposes. This project presents a manual ...

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 ...

Last year, Microsoft announced end-of-support for the RC4 stream cipher in 2016 for its Edge browser, as well as Internet Explorer 11. Earlier this year, the company reiterated that it would soon ...
