PROBLEM TO BE SOLVED: To provide a communication terminal capable of properly improving security at remote access time. SOLUTION: A user terminal 1 is composed of a notebook type personal computer capable of mobile radiocommunication, and stores an enciphered telephone number in an internal storage part. Enciphered ID and a password are stored in an IC card installed in the user terminal 1. The user terminal 1 reads out object data from the internal storage part when starting dial-up authenticating processing, and decodes the data into the telephone number, and reads out the object data from the IC card 2, and decodes the data into the ID and the password. The decoded telephone number is dialed, and is decoded toward an RAS server 31, and the ID and the password are transmitted. The user terminal 1 erases decoded information when establishing the communication after calling back. |
