To make the system more secure and robust, threshold schemes are proposed to avoid single point failure. At the same time, there are more and more applications which utilize the two basic blocks encryption and digital signature to secure message delivery (such as SSL, SSH). Combining the three tools organically leads to an interesting security tool termed as threshold signcryption which can be used...
Trojan is a threat to network security which poses a serious threat to national security. Through research on Trojan communication process, this paper proposes a data stream clustering method based on packet timestamp. This method uses cluster to compress Trojan communication data stream information, extracts cluster characteristics and then detects Trojans according to the cluster characteristics...
Wireless sensor networks (WSNs) are often deployed in hostile and unattended environments; they are vulnerable to physical capture and compromise. In a node replication attack or a node clone attack, an adversary physically captures a sensor node, extracts cryptographic secrets from the node, and distributes a large number of replicas of captured node throughout the network, in order to launch a variety...
