How long will the AES last?
No one can be sure how long the AES – or any other cryptographic algorithm – will remain secure. However, NIST’s Data Encryption Standard (DES) was a U.S. Government standard for approximately twenty years before it was known to be “cracked” by massive parallel network computer attacks and special-purpose “DES-cracking” hardware. The AES supports significantly larger key sizes than what DES supports. Barring any attacks against AES that are faster than key exhaustion, then even with future advances in technology, AES has the potential to remain secure well beyond twenty years. Implementation, Testing, and Use of the AES 19.
