Definition of Encryption
Encryption is the process of converting information into a code to prevent unauthorized access. Essentially, it transforms readable data, known as plaintext, into an unreadable format called ciphertext. Only authorized parties, who possess the correct decryption key, can convert ciphertext back into plaintext.
There are two main types of encryption: symmetric and asymmetric. In symmetric encryption, the same key is used for both encryption and decryption. In contrast, asymmetric encryption employs a pair of keys: a public key for encryption and a private key for decryption. Each method has its unique applications and security implications.
Historical Context
The history of encryption can be traced back thousands of years to the ancient civilizations that utilized rudimentary techniques to send secure messages. For instance, the Caesar cipher, named after Julius Caesar, involved shifting letters in the alphabet by a fixed number. This early form of encryption demonstrates the legacy of ensuring privacy in communication.
As technology advanced, so did techniques in encryption. During World War II, the Enigma machine exemplified the complexity of encryption used in military communications.
