In 2001, after an open competition, an encryption algorithm named Rijndael invented by cryptographers Joan Daemen and Vincent Rijmen was standardized as Advanced Encryption Standard (AES) with minor modifications by NIST.
So far, no attack has been found against AES that is more effective than the brute-force method.
A Complete Guide to Understanding This Blockchain Concept
The original version of Rijndael permits different key and block sizes of 128-bit, 192-bit, and 256-bits.
In the AES standard, however, only a 128-bit block size is allowed.
However, key sizes of 128-bit, 192-bit, and 256-bit are permissible.
Why This Matters for Blockchain Technology
Understanding Advanced Encryption Standard is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
