The Diffie-Hellman algorithm enables two systems to exchange a symmetric key securely without requiring a previous relationship. The algorithm allows for key distribution, but does not provide encryption or digital signature functionality. The algorithm is based on the difficulty of calculation discretion logarithms in a finite field. Although the Diffie-Hellman algorithm is vulnerable to a man-in-the-middle attack, it does not mean this type of compromise can take place anywhere this algorithm is deployed. Most implementations include another piece of software or a protocol that compensates for this vulnerability.
