What Is Encryption in Computer Security?

Data encryption is a powerful security measure that encrypts sensitive information into a non-readable language to ensure that only the intended receiver can decode it. It is a vital aspect of digital transformation, as it safeguards the confidentiality of information stored on computer systems or networks, such as the Internet. It provides integrity and authentication to ensure that the data is not altered or altered in the process of storage or transmission.

The process of encrypting data involves converting the original data into a format that can only be read with a key or password. In most instances, the recipient is able to then convert the encrypted text back to its original form. Modern encryption techniques use algorithms that scramble original data into ciphertext. A variety of methods and algorithms are used for this purpose that include transposition and substitution techniques. The Caesar cipher, named after the Roman Emperor Julius Caesar, is an early example of a cipher for substitution that is where each letter is replaced by one that is a specific number of times along the alphabet (e.g., “E” is changed to “Y”).

Encryption can be required to ensure compliance with regulations imposed by various organizations or standard bodies, including the Fair Credit Reporting Act (FCRA) and other consumer protection laws. It is also bigtechinfo.com/ a key security measure to protect sensitive information about clients, companies or patient information against cyberattacks. Retailers must, for example secure credit card information and shipping information when they transfer data between systems or across networks. The encryption process is able to protect information stored on computers and USB devices from being stolen by hackers.
