Happy #cybertiptuesday Today we talk crypto-agility. In basic terms, this is the ability to be able to switch your encryption methods quickly.
Why would you want to do that? All combination locks can be defeated if someone has enough time to do it. There is a finite number of combinations that are in place. They rely on the fact that an attacker doesn't have enough time to solve the puzzle before they are discovered, the combo is changed or their mortal life ends before they can solve it.
56-bit DES encryption was the standard when it was released in 1977. At the time, it would take many lifetimes to defeat the algorithm using a brute force attack. However, with increased computing power, it can now be defeated within hours. Therefore, making it unusable for security.
This issue will continue to raise problems with any encryption method developed as Quantum computing continues to solve complex problems at a lightning rate. That is why it is important for developers to be prepared to incorporate cyber-agility into their applications so they can quickly change their security to new innovations as past algorithms are defeated. #cryptoagility #quantumcomputing #bruteforceattack
