Vint Cerf, on TCP/IP security choices made during the 1970's

I don't know about surveillance. He was speaking on authentication and security.

In the mid-1970's while he was developing the regular--later to be public internet, he was also working with the NSA developing a secure internet using classified encryption methods.

While his colleagues at the time, Diffie–Hellman, had come up with the concept of key exchanges, they had no algorithms and he couldn't say anything to them. He was schizophrenic (his word) in that he wanted to add his view but couldn't.

What he was saying in the video, was that looking back, he would have liked to include better authentication and encryption in the regular internet.

It was an interesting video. He's done many others as well.
