By subtle touches, the National Security Agency (NSA) of the United States confirmed the veracity of the revelations made by Edward Snowden and the American media since 2013.
In an article published in February 2015 by the American Mathematical Review Records , Michael Wertheimer, the research director of the NSA, recognizes that the agency has attempted to impose on the international community the use of an algorithm cryptography was trapped; the random number generator component encryption keys contained a backdoor that could predict the generated numbers, and thus easily break yet deemed inviolable keys.
Addressing his peers in the American mathematical community, Michael Wertheimer has engaged in an unusual mea culpa beginning:
“In retrospect, the NSA should stop promoting the dual algorithm EC_DRBG when security researchers discovered the possibility of a backdoor.
“Then he called
it” regrettable “decision to continue to support the use of this false-random generator. For the future, he said that
“we will be more open and transparent about our contributions to the development of cryptographic standards.”
That said, in the collection of personal information and respect for the privacy of citizens, Michael Wertheimer reaffirms that the NSA is almost
perfect, “the NSA algorithms eliminate approximately 99.998% of the data which it has access … After this filtering process, the remaining data must meet strict conditions before being selected for processing and analysis.
