A VoIP encryption module was designed to prevent eavesdropping on Internet telephones communications and involved encoding/decoding the output data at the transmitter and receiver of the Internet telephone. To reduce the voice delay, a 128 bit AES was used and an RSA algorithm for an asymmetric encoding system was used during the key exchange, which is the(More)
We introduce both high-speed transmitting and quality of system offering Internet services on the HFC (Hybrid Fiber Coaxial) network with low installation cost. It modulates the phase and the amplitude to the carrier wave signal of the IPBS (Internet Protocol Broadcasting Service) data being acquired from Layer 3 switch. The proposed system is effective to(More)
