ENCRYPTION COMMUNICATION APPARATUS AND METHOD FOR CONTROLLING TRANSFER PERIOD OF KEY RESYNCHRONIZATION INFORMATION

摘要

An encryption communication apparatus and a method thereof are provided to improve communication quality by reducing a left packet due to a decoding failure of a receiving side. A transmitting/receiving part(110) receives packets from a transmitting unit(200). The transmitting/receiving part transmits net state report information generated through a net state report information generating part(130) to the transmitting unit. A packet analyzing part(120) calculates a packet loss rate and a net transmitting delay time by extracting a packet transmitting time and a packet order number inside a transmitted packet from the transmitting unit. The net state report information generating part determines a state of a net by using the packet loss rate and the net transmitting delay time. The net state report information generating part generates net state report information according to the state of the net.
