Abstract: A virtual private network (VPN) extends a private network across a public network, such as the Internet. The purpose of this research study is to implemented ATHS3 stream cipher and VEA ...

The Python program will implement the RC4 algorithm using a given key. The program should accept plaintext and a key as input, and output the corresponding ciphertext in hexadecimal format. It should ...

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

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 ...

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 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 ...

The creators of banking trojan programs in Brazil are using sophisticated block ciphers to encrypt their malware, making detection by anti virus products more difficult. The creators of banking trojan ...
