In order to solve the problem that the traditional covert length channel can not works safety on the Internet, a novel mode of covert packet length channel was proposed. By the mode, the covert information is tuned into the network packets through the parity of their length. Aims to test the safety of covert packet length channel, detection algorithm based on neuron network which works well to find the covert time channel was introduced to identify a covert packet length channel. The detection experiments show that the data of covert length channel cannot be distinguished from that of normal communication. As a result, covert length channel is a security tool for covert communication of computer network.
