One disadvantage of symmetric cryptosystems which require private key like AES is that the private key must be exchanged. And Diffie-Hellman key exchange algorithm enables exchange private keys over a public channel. So it can solves following dilemma. Alice and Bob want to share a secret key which is going to be used in a symmetric cipher,… 더 보기 »Diffie-Hellman Key Exchange
