Abstract
An apparatus and method for controlling a packet transfer period of key resynchronization information in an encryption communication system are provided. The encryption communication apparatus includes a receiving means that computes a packet loss ratio and a network transfer delay time through a received packet when the packet is received and generates network status report information for a packet size and a packet transfer period of key resynchronization information using the packet loss ratio and the network transfer delay time, and a transmitting means that transmits a packet of the key resynchronization information in the transfer period by controlling the packet size and the packet transfer period of the key resynchronization information according to the network status report information received from the receiving means when data is input.
