The more complex the cryptographic key, the more secure the encryption – because third parties are less likely to decrypt it via brute force attacks (i.e. The recipient uses the key to decrypt the data, turning it back into readable plaintext. Encryption involves using a cryptographic key, a set of mathematical values both the sender and recipient agree on. Essentially, this means taking readable data and changing it so that it appears random. These processes are known as encryption in network security.Įncryption involves converting human-readable plaintext into incomprehensible text, which is known as ciphertext. #What is encoding in cyber security install#To prevent this, users can install specific software or hardware to ensure the secure transfer of data or information. As data travels through the public internet, there is a chance it could be compromised or stolen by hackers. When information or data is shared over the internet, it goes through a series of network devices worldwide, which form part of the public internet. Data encryption software, also known as an encryption algorithm or cipher, is used to develop an encryption scheme that theoretically can only be broken with large amounts of computing power. That information could include everything from payment data to personal information. It is the simplest and most important way to ensure a computer system's information can't be stolen and read by someone who wants to use it for malicious purposes.ĭata security encryption is widely used by individual users and large corporations to protect user information sent between a browser and a server. Encrypted data can only be read or processed after it's been decrypted.Įncryption is the basic building block of data security. Encryption in cyber security is the conversion of data from a readable format into an encoded format.
