How are symmetric keys shared
WebTo communicate using symmetric key cryptography each pair of people must share a key. This leads to the N (N-1)/2 equation. However, most systems will assume your keys are uni-directional so each sender has a unique key for each receiver, this doubles the number of keys to N (N-1).
