Modern encryption methods using the RC4 algorithm

Keywords: confidentiality, cybersecurity, cryptography


Nowadays, data encryption and privacy are one of the most important issues. In this article, we will look at modern encryption methods and reveal all aspects related to the relevance of use and vulnerability of the RC4 algorithm. Encryption techniques are the process of converting plaintext data into encrypted text in order to hide its value and thus prevent an unauthorized recipient from obtaining the original data. Therefore, encryption is mainly used to ensure confidentiality. Companies typically encrypt their data before transferring to make sure the data is secure during transit. Encrypted data is sent over a public network and decrypted by the recipient. Before the advent of the Internet, cryptography dealt only with encrypting messages – converting messages from intelligible to incomprehensible, making them unreadable to the person who intercepted the message, and reverse conversion by the recipient while preserving the essence of the message. In recent years, cryptography has begun to expand and, in addition to secret messaging, has begun to include methods for verifying the integrity of messages, secure communication technology, sender and recipient authentication (using keys, digital signatures, etc.), and more. This article will discuss the RC4 algorithm, also known as ARC4 or ARCFOUR – streaming cipher, which is widely used in various information security systems in computer networks (eg, SSL and TLS, wireless security algorithms WEP and WPA).
