Abstract A method for down-loading secret document in an unsafe communication channel features that the server can down-loading the secret key to the user according to user's cipher without transmission of said cipher to the server. This protocol includes two transmission steps: the first step is for user to transmit user ID, V and K to server, and the second step is for server to receive said values and judge if the user is true. The values obtained by hash function operating with parameters Pa and ID are stored in said server. Its advantage is high safety.
