What is the AES encryption algorithm?

The AES encryption algorithm is used by government authorities of the United States for encrypting confidential data. It is now used for classified and non -classified data. The algorithm has been published publicly and is likely to be widely used in the commercial sector. Classified data is that if the law limits to which people have access to data. The AES encryption algorithm was approved as the standard of the Federal Government in 2002, and in 2003 it received approval for use in classified documents. Since 2010, it has been the only public accessible encryption system approved for classified documents. The data encryption standard, first received in 1976, used a 56 -bit key, which means it could be reduced to 56 characters, each of them either 1 unfortunately 0. This meant that the probability of correct guessing was one of the 72 quadrillion, which can also be expressed as one of the 72 thousand million. In other words, on average it would be on average one of the 36 attempts to correctly guess the entire key and beAble to decrypt encrypted messages without authorization.

At that time it looked so difficult that it was virtually impossible. As the computing power increased, it became more feasible. In 1999, the experiment showed that the computer can break the algorithm in less than one day to simply try every possible combination of 1s and 0s. This is known as an attack of brutal force. Officials tried to face the development of "triple des", where there are three separate keys for each data set, but there were still a call for a new system.

AES algorithm is much more complicated. It consists of three separate keys, which are128, 192 and 256 bits. The likelihood of cracking the algorithm is, at least huge. With the exception of people who are already familiar with the Quattuorvigintillion unit, it is probably safe to say that chances are unimaginable!

This does not mean that there will never be a powerful computer enough to breakIl ae through rough power, but at the moment it would be virtually impossible. Even if the computer could be powerful enough, any existing manufacturing techniques would make it impossible to build such a machine in a manageable size. Indeed, anyone who is trying to build such a machine would probably attract the interest of the US government long before they could break the algorithm.
