![]() ![]() After three summits in 1998, 19, NIST announced that Rijndael was the winner and would henceforth be known as AES. Originally named Rijndael, the encryption was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, in the mid-to-late 1990s.Īlong with 14 other protocols - including the four that would go on to compete with Rijndael: namely, Twofish, Serpent, RC6 and MARS - it was submitted to NIST for consideration as the new industry standard for encryption. National Institute of Standards and Technology (NIST, for short). ![]() The History of AESĪs we’ve already mentioned, AES simply stands for “Advanced Encryption Standard,” a name it adopted when it was chosen as the industry standard for encryption by the U.S. If you need a more in-depth explanation of the basics of encryption, head over to our general description of encryption before continuing. However, a separate secret private key has to decrypt it again. The opposite of symmetric encryption is (surprise, surprise) “asymmetric encryption,” where a publicly available key encrypts the data. In short, though, encryption generally works by taking a piece of data you want to keep confidential and scrambling it, making it unreadable to anyone who doesn’t have the secret key required to unscramble it.ĭifferent protocols go about this differently, with some - such as AES - utilizing a “symmetric-key algorithm,” which means that the same key encrypts and decrypts the data. What Is Encryption?Įncryption is a wide topic that takes years to fully understand, so we won’t take up too much space in this guide to explain the fundamental principles of the practice. What Is AES Encryption? Breaking Down the BasicsĪs is the case with walking before running, to understand what AES is, we need to explain some basics about encryption and how AES encryption came to be. ![]() For example, without encryption, things like your banking details, medical records and even purchases would be far too exposed to exist safely in a digital space. Unless you’ve been living in a cave for the last 20 years, you’re pretty much guaranteed to have used software that uses it, even if you have no idea what it is.Įncryption allows us to use computers and the internet to perform tasks and store sensitive data that needs to be confidential. Since its adoption in 2000 as the industry standard, AES has become ubiquitous in every part of our digital lives. With current technology, AES is uncrackable through straightforward, brute-force attacks, and it is used in countless applications, from protecting top-secret or classified information in government agencies to keeping your personal data safe when stored on the cloud.The two most common versions are 256-bit AES (providing greater security) and 128-bit AES (providing better performance during the encryption and decryption process).The AES algorithm is the industry-standard encryption protocol that protects sensitive information from traditional brute-force attacks.AES stands for “Advanced Encryption Standard.”.So, what is AES encryption exactly, and how does it work? Join us as we break down the popular encryption protocol to its core components in an effort to decipher some of the technobabble surrounding encryption. If you’ve done research into any kind of consumer software - whether it’s cloud storage, backup providers or virtual private networks - you’ve likely come across the phrase “AES.” You generally don’t get an explanation beyond that, though.
