Key Exchange protocols typical precede secure communications.

In the 1970's and onward, key exchange was typically a mechanical process were encryption or signing keys were distributed by physically embedding the key in a piece of hardware that was then put into tamper-evident packaging an physically moved to both ends of the secure communications channel.^[1]
With the advent of Public Key Cryptography, various Key Exchange protocols have been developed that use some sort of Public Key Infrastructure to initiate a secure communication channel.
With the advent of Public Key Infrastructure provably security Key Exchange is possible and in 2021 had been demonstrated.
