Signatures with partially message recovery in which some parts of messages are not transmitted with signatures to make them shorter are useful where bandwidth is one of the crucial concern and especially in case of signing short messages in applications such as time stamping, certified email services and identitybased cryptosystems. In this paper, to have quantum-attackresistant short signature...

Background Addiction to opiates and synthetic opioids poses a major threat public health worldwide, with pharmaceutical prescribed manage pain constituting the main problem. To counteract this threat, suitable management strategies should be implemented in care. Monitoring seems feasible using telemedicine certain degree of resource intensity digitization. As communication channel for type moni...

In view of the problem that lack wireless mobile network in remote mountainous areas makes transmission line online monitoring data difficult, this paper proposes a scheme using Beidou short message communication. And aiming at problems small and low reliability communication, new coding method is designed. The actual results show that: proposed system based on communication has high success ra...

In networks with unstable links the connection between the sender and the receiver may be cut before the entire message has been transmitted. Quantization of the message into blocks before its transmission, enables message fragments consisting of one or more such blocks to be transmitted successfully, even if the connection time is too short for transmitting the entire message. But fragmentatio...
