Abstract
First communication units use a public key thereof certified by a certification authority on a PKI (Public Key Infrastructure), which is held by the first communication units in advance, and a secret key of the first communication units or delegation information generated by using secret information, as public key certificate, of the first communication units to thereby allow a proxy server to perform security processing, i.e. key exchange processing, authentication processing or processing for providing compatibility of encryption schemes, between the first communication units and a second communication unit on behalf of the first communication units.
