This paper investigates infinite horizon repeated security games with one defender and multiple attacker types. The incomplete information brings uncertainty of attackers' behaviour for the defender. Under the uncertainty of attackers' behaviours, we take the worst-case analysis to minimise the defender's regret w.r.t. each attacker type. We wish t...

To reduce the number of deaths and injuries due to drunk driving (also referred to as drink driving, driving while intoxicated, and driving under the influence of alcohol in the literature), many countries have deployed public safety resources to inspect traffic network. However, challenges remain in allocating limited public safety resources to th...

To penetrate sensitive communication systems, attackers can attack the channel using an active time-varying (ATV) way, which will lead to a great information loss. The conventional approach is to encrypt the original signal making it difficult for attackers to get information. However, this technology is constrained by the limited wireless terminal...

In some security domains, the defender holds more private information than the attacker, such as the authenticity of resources. A mock camera can be adopted by the defender to deter potential attackers while the attacker may see it as a real one. This provides an opportunity for a defender with fake resources to bluff, as if all resources she owns...

In peer-to-peer service networks, autonomous agents gain utilities through getting services from others. However, providing services is so costly that rational agents may prefer to defect rather than to cooperate. In order to provide scalable and robust services in such networks, incentive mechanisms need to be introduced. In this paper, we propose...

In the traditional secret image sharing schemes, a dealer shares a secret image among a group of participants and an authorized subset of the participants with their shadow images can cooperate to retrieve the secret image. However, for a long live secret image, the intruders may have adequate time to gain enough amounts of the shadow images. In th...

Trust violation during cooperation of autonomous agents in multiagent systems is usually unavoidable and can arise due to a wide number of reasons. From a psychological point of view, the violation of an agent’s trust is a result of one agent (which is a transgressor) expressing a very low weight on the welfare of another agent (which is a victim)...

Secret image sharing has been researched intensively, and it has emerged as an alternative to data hiding for protecting the security and privacy of important data. In the traditional (t, n) threshold secret image sharing schemes, any t or more shadow images can reconstruct the shared secret image. However, in real applications, (t, n) threshold ac...

Many incentive mechanisms have been proposed to encourage cooperation among agents in autonomous networks, but the altruism attribute of agents is considered very few in such mechanisms. In this paper, we introduce other-regarding preference (ORP) and fitness factor 𝜃 into incentive mechanism to more realistically characterize the altruism of agent...

The violation of trust as a result of interactions that do not proceed as expected gives rise to the question as to whether broken trust can possibly be recovered. Clearly, trust recovery is more complex than trust initialization and maintenance. Trust recovery requires a more complex mechanism to explore different factors that cause the decline of...

The vertical displacement of a cross section of a bridge has a close correlation with the carrying capacity and the ability to resist dynamic loads. Therefore it has been one of the most important parameters for structural health monitoring and safety assessment. Moreover, when a natural disaster such as a hurricane or an earthquake occurs, a large...

The terrorist’s coordinated attack is becoming an increasing threat to western countries. By monitoring potential terrorists, security agencies are able to detect and destroy terrorist plots at their planning stage. Therefore, an optimal monitoring strategy for the domestic security agency becomes necessary. However, previous study about monitoring...

Reputation systems have been proposed to distinguish malicious peers and ensure the quality of services in P2P networks. How-ever, only relying on global reputation scores to assess the reliability of file providers can weaken the subjective opinions of file requesters, which is vulnerable to some malicious attacks, e.g., camouflage attack. To addr...

In peer-to-peer (P2P) file sharing networks, it is common practice to manage each peer using reputation systems. A reputation system systematically tracks the reputation of each peer and punishes peers for malicious behaviors (like uploading bad file, or virus, etc). However, current reputation systems could hurt the normal peers, since they might...

Reputation-based mechanisms are most effective mechanisms to defend data pollution attacks in P2P streaming systems. In this paper, we propose a dynamic reputation...

P2P systems provide peers a dynamic and distributed environment to share resource. Only if peers are voluntarily share with each other can system stably exist. However, peers in such systems are selfish and never want to share even with tiny cost. This can lead to serious free-riding problems. Incentive mechanisms based on evolutionary game aim at...

Asymmetric group key agreement is a cryptographic primitive allowing a group of users to negotiate a common public encryption key while each of them holds a different secret private decryption key. Anyone (including outsiders) with the public encryption key can send encrypted messages to the group members, and then the group members can decrypt the...

The communications in the quake-hit area are always cut off from the outside after the earthquake, and the traditional seismic field investigation method calls for immense time to accomplish house-to-house investigation, which goes against timeliness of the emergency rescue. In this paper, an emergency communication and quick seismic damage investi...

In secret image sharing schemes, the threshold may have to be adjusted in case of changes in the security policy and the adversary structure before recovering the secret image. For example, if participants leave the group, their stego images are useless to them and may not be kept safely. As a result, these images can be easily stolen and utilized...
