Tóm tắt:Â In 2013 the American computer specialist Edward Snowden illegally downloaded roughly 1,7 million top-secret documents of the U.S. National Security Agency (NSA). Â It was the largest loss of secret information by any government of any country ever. Â Among other revelations, the Snowden documents showed that the NSA had put a "back door" (secret entrance-way that only the NSA could use) into a commonly used cryptographic standard for generating random bits. Â This random bit generator uses elliptic curve cryptography (ECC), and I will describe the mathematics of this "back door". Â In addition, based on conversations with several people who are close to the controversy as well as my own analysis of the lessons to be learned, I will give an interpretation of the main issues for cryptographers and others who are professionally interested in protecting personal security and national security in their own country. |
