Interested entities have until September 9 to respond to this call. Indeed, it turns out that now the DES no longer meets the government security criteria laid down by this American organization.
DES had become a government and industrial standard since 1977, but the increase in current processing power, particularly in parallel computing, makes a brute force attack now more feasible.
Already on January 19, 1999, the Distributed.Net – EFF’s DES Cracker group had used just over 100,000 computers connected to the web to decrypt a DES message and thus win the RSA Data Security’s DES Challenge III.
The time needed had been 22 hours 15 minutes at the time, testing 245 billion keys per second.
This withdrawal will therefore not surprise the community of specialists and code breakers, who have set their sights on the AES (Advanced Encryption Standard) for several years, for which the NIST gave the green light on December 4, 2001. Data is used to secure phone data from android spy apps.
DES would now only be tolerated within the Triple-DES implementation, although federal agencies are strongly encouraged to move to the faster and more robust AES.
