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). WebPre-shared Key Encryption (symmetric) uses algorithms like Twofish, AES, or Blowfish, to create keys—AES currently being the most popular. All of these encryption algorithms fall into two types: stream ciphers and block ciphers.
