“Documents leaked by the former NSA contractor Edward Snowden show that the NSA created and promulgated a flawed formula for generating random numbers, to create a ‘back door’ in encryption products, the New York Times reported in September. Reuters later reported that RSA became the most important distributor of that formula by rolling it into a software tool called Bsafe that is used to enhance security in personal computers and many other products. Undisclosed until now was that RSA received $10m in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract.”
