Citation de l'article : "This is not to say that anyone is in immediate danger and, according to Bogdanov, although it is four times easier to carry out it is still something of an involved procedure. Recovering a key is no five minute job and despite being four times easier than other methods the number of steps required to crack AES-128 is an 8 followed by 37 zeroes. "To put this into perspective: on a trillion machines, that each could test a billion keys per second, it would take more than two billion years to recover an AES-128 key," the Leuven University researcher added. "Because of these huge complexities, the attack has no practical implications on the security of user data." Andrey Bogdanov told The INQUIRER that a "practical" AES crack is still far off but added that the work uncovered more about the standard than was known before. "Indeed, we are even not close to a practical break of AES at the moment. However, our results do shed some light into the internal structure of AES and indicate where some limits of the AES design are," he said."
