Security firm RSA has denied allegations that it worked with the US National Security Agency (NSA), and has taken a $10m payout from it.
Reuters claims sources have informed it about the secretive deal, which follows on from Edward Snowden's PRISM spying revelations. RSA denied involvement.
The firm said in a statement: "RSA always acts in the best interest of its customers and under no circumstances does RSA design or enable any backdoors in our products. Decisions about the features and functionality of RSA products are our own."
The report talks of two sources for its information, and adds that the sum is worth about a third of the relevant RSA division's annual revenues.
In a blog post on Monday the firm denied allegations about the payoff, saying that it has no such relationship with the NSA.
"Recent press coverage has asserted that RSA entered into a 'secret contract' with the NSA to incorporate a known flawed random number generator into its BSAFE encryption libraries. We categorically deny this allegation. We have worked with the NSA, both as a vendor and an active member of the security community. We have never kept this relationship a secret and in fact have openly publicised it. Our explicit goal has always been to strengthen commercial and government security," it said.
"RSA, as a security company, never divulges details of customer engagements, but we also categorically state that we have never entered into any contract or engaged in any project with the intention of weakening RSA's products, or introducing potential ‘backdoors' into our products for anyone's use."
Reuters maintains that it is standing by its story.
