METHOD FOR VIRTUALLY AUTHENTICATING A CLIENT BASED ON INFORMATION ISSUED FROM A NETWORK IN WHICH AN AUTHENTICATION PROCESS IS EXECUTED

摘要

PURPOSE: A method for virtually authenticating a client is provided to enable a service provider and a user to reduce costs for connecting to a network.;CONSTITUTION: A client information collecting unit collects information used for receiving authentication information from a server (S202). An information processing unit processes collected information (S203). A hash value calculation unit generates hash values which are able to be predicted and are divided into fixed information and variable information (204). A hash value calculation unit generates the hash values by using codes issued from the server (205).;COPYRIGHT KIPO 2013;[Reference numerals] (201) Use client authentication?; (202) Collect information about a client; (203) Process information; (204) Generate predictable hash values; (205) Generate a hash value using codes issued by a server; (206) Anyone of the values in (204) accords with the value in (205); (207,208) Authentication failure; (301) Use network authentication; (AA) Start; (BB,EE) No; (CC,FF) Yes; (DD,GG,HH) End
