Search protocols are among the main applications of RFID systems. Since a search protocol should be able to locate a certain tag among many tags, not only it should be secure against RFID threats but also it should be affordable. In this article, an RFID-based search protocol will be presented. We use an encryption technique that is referred to as authenticated encryption in order to boost the ...

The security of information systems has been the focus because of network applications. Vulnerability analysis is widely used to evaluate the security of a system to assure system security. With the help of vulnerability analysis, the security risk of a system can be predicted so that the countermeasures are arranged in advance. These will promote system security effectively. The object of vuln...

The approach to network security analysis is suggested. It is based on simulation of malefactor’s behavior, generating attack graph and calculating different security metrics. The graph represents all possible attack scenarios taking into account network configuration, security policy, malefactor’s location, knowledge level and strategy. The security metrics describe computer network security a...
