Unconditionally secure signature is an important part of quantum cryptography. Usually, a signature scheme only provides an environment for a single signer. Nevertheless, in real applications, many signers may collaboratively send a message to the verifier and convince the verifier that the message is actually transmitted by them. In this paper, we give a scalable arbitrated signature protocol of classical proved to be secure even with a compromised arbitrator. messages with multi-signers. Its security is analyzed and proved to be secure even with a compromised arbitrator.

Digital rights management (DRM) is indispensable to prevent various kinds of illegal content usage. In this paper, we present a Digital interface-based DRM scheme (DI-DRM) for digital cinema, which can provide a new multi-interfaces oriented DRM solution for dig- . ital cinema. The authentication protocol and the encryption algorithm are described in detail. The two kinds of digital interfaces-based DRM prototype system are developed. security and performance analysis show the proposed scheme has several advantages. First, it is more secure than the existing scheme. Second, it is supported more rights, including the downstream devices. Finally, the cost of the chip based on DI-DRM is low. The scale of SOC application scheme is only 1/3 to 1/6 of the existing DTCP.

To evaluate the security situation of hierarchical network, a novel evaluation algorithm based on the method of constructing a security risk function is proposed. The proposed algorithm is the aggregation of qualitative evaluation and quantitative evaluation. We quantify the asset loss (AL) and the threat value of each attack step (TVA) basing on attack graph, and adjust the loss of assets that are of the same type and have different uses with coefficient of asset importance (CAI). Then, we construct a risk evaluation function which is based on the above three parameters. Thus, the assessment score gotten through the evaluation function can comprehensively reflect the risk value including loss, threat of an attack step, and importance of the suffering entity. Finally, we get the risk value by fusing all subnets'risk value in one area, and divide the risk value into 4 security levels. Seen from the case study, the model solves the security evaluation problem for hierarchical network simply and efficiently. © 2010 IEEE.

Performance analysis of sign quantized projection

The Journal of China Universities of Posts and Telecommunications 2010年第1期17卷 62-66页

Quantized projection technology （QP） is the version of quantization index modulation （QIM） working in the projection domain. It essentially belongs to a double-sided additive embedder. In this article, the concept of sign quantized projection （SQP） is proposed, which differs from the conventional QP when working as a single-sided embedder. Theoretical analysis reveals that SQP has the same probability of miss and probability of false alarm as QP. Also, the document-to-watermark ratio （DWR） of SQP is less than its counterpart of QP by lOlg（1＋ γ） dB.

Recently, wireless Sensor networks (WSNs) have been paid more and more attention and are widely used in a lots of military and commercial applications. Due to the limited communication and computation capabilities, there are many security issues which should be take into account. In this paper, we proposed a flexible security management framework which combines the existed method to overcome the drawbacks of early research. In the proposed method, we analyze the attacks of the WSNs by data mining and uniformly implement the protection scheme through a control platform. We deployed the proposed framework on the sensor network to evaluate its performance and the experiment shows our method can achieve a satisfied result. © 2010 The Journal of China Universities of Posts and Telecommunications.

One important function in trusted computing is protected storage, which can protect unlimited amount of data and keys. In the existing trusted platform module （TPM） key loading scheme for trusted platform, a computing platform with TPM as its trusted anchor, the total times of loading operation is the same as the number of the loaded target object＇s ancestors, resulting in low efficiency of loading a TPM key which has many ancestors. To improve efficiency, an identity-based TPM key loading scheme is proposed. In this scheme, the times of loading operation is only two when any TPM key is loaded into TPM. Therefore, the required time cost for loading a TPM key can be reduced, especially for complex TPM key storage hierarchy. By analyzing the correctness, security, efficiency and feasibility, the proposed scheme has the better theoretical and application value.

Secure boot is one important way to ensure the security of system for the terminal computing platform. The existing solutions for platform secure boot are based on verification by matching the reference measurements with the runtime measurements. These solutions are complex and inefficient. Based on the existing secure boot scheme, a secure boot model based on trusted personal computer (PC) is designed. Through the use of the existing trusted computing technology, a seal-based secure boot scheme for trusted computing platform is proposed in this paper. In this scheme, it is not necessary to generate the certificates on components of the reference measurements;it is also not necessary for verification proxy to verify the integrity of the runtime measurements. At the same time, the security of platform system is effectively guaranteed during booting. © 2010 The Journal of China Universities of Posts and Telecommunications.

network traffic classification based on semi-supervised clustering

Journal of China Universities of Posts and Telecommunications 2010年第SUPPL. 2期17卷 84-88页

The diminished accuracy of port-based and payload-based classification motivates use of transport layer statistics for network traffic classification. A semi-supervised clustering approach based on improved K-Means clustering algorithm is proposed in this paper to partition a training network flows set that contains a huge number of unlabeled flows and scarce labeled flows. The variance of flow attributes is used to initialize clusters centers instead of the random selection of the cluster centers in initialization. Scarce labeled flows are selected to construct a mapping from the clusters to the predefined traffic classes set. The experimental results show that both the overall accuracy and square error (SSE) value of our algorithm present better than those based on normal K-Means algorithm defined in Ref. [5]. © 2010 The Journal of China Universities of Posts and Telecommunications.

Variable-rate convolutional network coding

The Journal of China Universities of Posts and Telecommunications 2010年第3期17卷 91-96,117页

作者： MA Song-ya CHEN Xiu-bo LUO Ming-xing Information Security Center State Key Laboratory of Networking and Switching TechnologyBeijing University of Posts and Telecommunications Beijing 100876 China Key Laboratory of Network and Information Attack and Defense Technology Ministry of Education Beijing University of Posts and Telecommunications Beijing 100876 China National Engineering Laboratory for Disaster Backup and Recovery Beijing University of Posts and Telecommunications Beijing 100876 China School of Mathematics and Information Sciences Henan University Kaifeng 475004 China

Four types of variable-rate convolutional network codes are investigated over a single-source finite cyclic network. It is found that variable-rate generic, dispersion and broadcast can be implemented on the same network without changing the local encoding kernels of the non-source nodes. The efficient implementation has the advantage that each non-source node only needs to store one copy of the local encoding kernel within a session. However, it is also shown by an example that variable-rate multicast may not always be implemented under the above condition.
