This paper analyzes the information-theoretical security of the of Differential Phase Shift (DPS) Quantum Key Distribution (QKD) protocol, using efficient computational information geometric algorithms. The protocol was introduced for practical reasons, since the earlier QKD schemes were too complicated to implement in practice. The DPS QKD protocol can be an integrated part of current network security applications; hence its practical implementation is much easier with the current optical devices and optical networks. The proposed algorithm could be a very valuable tool to answer the still open questions related to the security bounds of the DPS QKD protocol.

In this paper, we propose a novel multiplication operation based on the cached operands and reordered partial products. The proposed method shows that the latency of the polynomial multiplication, which is the core operation of the ECC, is 6% smaller than previously known results.

In this paper, we present proxy zero-knowledge proof and utilize it in anonymous credential systems. In our proposed system, if a user cannot directly show a credential issued by an organization, instead of giving the secret key to the proxy, the user generates a proxy key based on the desired credential particularly for the proxy. Therefore, the proxy is neither the owner of the user's credential nor uses his or her other credentials.

We present a new efficient adaptive chosen-ciphertext secure proxy re-encryption scheme in the standard model. The scheme has less ciphertext and is different from other proxy re-encryption schemes in that it does need any strong unforgeable one-time signatures

In this paper, we propose a directional spread-spectrum modulation (DSM) signal transmitted by a switched antenna array for physical layer security communication. The main idea is that the antenna hopping scheme is designed according to a spreading sequence.

A network address translation-based solution is proposed and used to countermeasure an intentional denial of Internet access by higher-tier Internet service providers. The proposed solution is scalable, is transparent, and has negligible impact on network performance.

In this paper, we proposed the propagation model of the computer virus based on bounded rationality evolutionary game theory. Unlike classical computer virus propagation models, this model was built from the view of the evolutionary game process between normal users and potential attackers, and the loss of the users was also described accurately and quantitatively. By considering bounded rationality and information incomplete of the participators, the proposed model can describe the actual situation of the network virus spreading, and find key factors of influencing the spread of computer viruses on the network.

We propose a client-based scheme supporting interoperation between Shibboleth and information card systems such as CardSpace and Higgins. The scheme uses a browser extension and does not require any modifications to CardSpace or Higgins identity selectors, and only minimal changes to relying parties and identity providers. A proof-of-concept prototype is also described.

Greedy node captured based on route minimum key set captures node on the basis of an overlapping value that can be obtained through route minimum key set. The route minimum key set is calculated through the max flow of the flow network.

To detect the unknown malware, the features of graph-based method are predefined from function call graph of software, and then the rules are built with these features to classify an executable as the benign or the malware. The quantity and the contents of these features are independent of testing dataset, and this peculiarity enables our experiment results to nearly reflect the situation of unknown malware detection. The design can provide a high malware detection accuracy by using a small set of training set.

Highlights:

1. We propose a radio frequency identification (RFID) authentication mechanism on the basis of chaotic maps, which has been analyzed under the security model to withstand various attacks.
2. The use of our authenticated RFID mechanism achieves constantly secret updating for security concerns.
3. Our proposed mechanism exhibits higher efficiency than previous approaches that is more suitable for RFID environment.
