Security firm RSA has denied it entered into a contract that it knew would give the NSA a backdoor into its BSAFE security system. Last week,it was claimed that the NSA paid RSA $10 million to make an algorithm called “Dual EC DRBG” the preferred, or default system in BSAFE. The security giant says that, although it has worked with the NSA, the relationship has never been a secret, and the relationship has been with the “explicit goal” of strengthening security.
