Tells Google Hangout buds that tech was 'classified' at the time...
By John Leyden, 7 Apr 2014 The NSA acted as a barrier to the rollout of encryption as standard from the very inception of the internet back in the mid 1970s.Engineers had wanted to add a network encryption layer as part of the original specifications for TCP/IP. Whitfield Diffie and Martin Hellman had published a paper on public key cryptography systems, so the kernel of a technology to make the internet secure was already there.
However the algorithms that would have made the idea a practical reality had to wait until Ron Rivest, Adi Shamir and Leonard Adleman published the RSA algorithm in 1977.
Intel agencies including the NSA and GCHQ had already invented public key cryptography systems, but this work remained top secret.Meanwhile, Vint Cerf, the pioneering internet security engineer, was working on components of a classified NSA at Stanford in the mid 1970s to build a secure, classified internet.
