What Is Encryption in Computer Security?
Data encryption is a powerful cybersecurity measure. It scrambles sensitive data into unreadable gibberish that only the intended receiver can understand it. It is an essential component of digital transformation, as it safeguards the confidentiality of the data stored on computers or networks such as the Internet. It offers integrity and authentication and ensures that data isn’t altered or altered when it is stored or transmitted.
The process of encryption involves converting the original data into a format that can only be read using a password or key. In most instances, the recipient will translate the encrypted data back to its original form. Modern encryption techniques utilize algorithms that convert original data into the ciphertext. A variety of methods and algorithms are used for this purpose, including substitution and transposition techniques. The Caesar cipher is an early example of a substitute cipher. Each letter is replaced with a new one at a set number of positions in the alphabet.
The use of encryption can ensure compliance with the regulations set by different organisations or standard bodies, including the Fair Credit Reporting Act (FCRA) and other consumer protection laws. It is a critical security measure to safeguard sensitive information of a company or patient from cyber-attacks. Retailers, for example should ensure that their customers’ credit card and shipping information when transferring it between systems or over networks. The encryption process can protect information stored on computers and USB devices from being accessed by hackers.
