PURPOSE: Secure transmission amount calculation method and system using a relative distance variable in a wireless network in which a secure section exists are provided to calculate more realistic secure transmission amount by considering a relative distance between receiver and tapping node based on a transmitter. CONSTITUTION: A secure transmission amount calculation system determines a relative distance variable based on a radius of secure region and a distance between transmitter and receiver (401). The secure transmission amount calculation system determines optimal electric power distribution variable in a closed form (402). The secure transmission amount calculation system calculates a secure transmission amount by finding the optimal electric power distribution variable (403). [Reference numerals] (401) Determine a relative distance variable; (402) Determine an optimal electric power distribution variable; (403) Determine optimal secure transmission amount; (AA) Radius of a secure region(d_zone); (BB) Distance between a transmitter and a receiver(d_R); (CC) Secure transmission amount is closed; (DD) Disperse channel electric power; (EE) Secure transmission amount
