Rijndael encryption

Updated: 04/26/2017 by Computer Hope

EncryptionRijndael encryption is an encryption algorithm upon which AES (advanced encryption standard) is based. "Rijndael" is a portmanteau of the names of Joan Daemen and Vincent Rijmen, the inventors of the algorithm.

Rijndael uses a design principle known as a substitution-permutation network, or an SP-network, to encrypt plaintext data. It uses a series of mathematical operations; decryption is performed by reversing the process. It has a relatively simple algebraic description, and runs very efficiently on both hardware and software implementations.

In 2009, several cryptographers were able to exploit an aspect of the algorithm known as its key schedule to make an attack against the algorithm that was more efficient than a brute force attack.
