RADIO COMMUNICATION EQUIPMENT AND SERVER

摘要

PROBLEM TO BE SOLVED: To provide radio communication equipment which can improve secrecy of communication data without including complex cryptographic function on a portable terminal which applies radio communication to a communication means. SOLUTION: When communication contents are kept secrete in the portable terminal which applies radio communication to a communication means, communication to a radio base station is performed by using communication means of at least N (N is a natural number of at least two) paths. When the communication contents are transmitted and received, corrected data which are produced by operation of (N-1) random numbers and the communication contents are transmitted and received.
