Wireless sensor networks are often deployed in hostile and unattended environments. Then two important problems for key management are presented. First, how to establish the encryption keys among sensor nodes to ensure the security of the network applications. Second, how to avoid the key being obtained especially the sensor be captured. In this paper, we proposed a novel key management method based on PRC (Prime Residue Class) for the wireless sensor networks in the hostile environments. By using this method, we can establish reliable communication keys between sensor nodes and avoid the original key being obtained. Moreover, this method can save the energy during the key establishing process. We designed some experiment to evaluate the security and performance of this method, and the experimental results show that the proposed method can achieve satisfying results. © 2010 IEEE.

In this paper, a secure Content protection Secure Management Scheme about electronic documents (named CPSec EDMS) will be proposed, in which the architecture, key technology and authorization protocol, security analysis of CPSec EDMS will be discussed. To prevent document leakage, the client of CPSec EDMS adopts transparent encryption technology based on filter driver, in which the client encrypts files automatically. Considering the off-line mode exiting in the application, the client of the CPSec EDMS will call function of offline decryption interface, which is running in application layer. In view of different receiver, the CPSec EDMS will adopt different strategy, in which the client will encapsulate the permission and the ciphertext for the receiver internal while the receiver will apply for decryption from the server. In contrast, the client will encapsulate the permission and the plaintext for the receiver external. © 2011 IEEE.

Traditional total variation model leads to an undesirable staircase effect and is hard to eliminate high frequency noises in image restoration. In this paper, to solve this problem, a novel image restoration model based on adaptive total variation is proposed. A gradient fidelity term is coupled with adaptive total variation model. In order to choose proper parameters, the parameter selection criteria are analyzed theoretically, and a simple scheme to demonstrate its validity is adopted experimentally. To make fair comparisons of performances of three models, the same numerical algorithm is used to solve partial differential equations. Experimental results illustrate that the new model not only preserves the edge and important details but also alleviates the staircase effect effectively. © 2010 IEEE.

Modern software systems, which are often largescale, with multi-procedure and complex data structures, must be extremely high quality. We present a novel framework based on symbolic execution for automatic analysis of such systems and checking of properties. We provide an improved approach of the traditional symbolic execution, namely the General-Cutting symbolic execution. We change the ways of dealing with the function calls. The process of this new approach is divided into two stages. How to deal with calling context when accessing unknown input data and how to deal with the relationship between function callings are two main challenges to the General-Cutting symbolic execution algorithm. We adopt an extensible lazy initialization method and General Execution Map Cutting method to handle these problems. It can deal with arbitrary and complex input data. ©2009 IEEE.

Expression of blind message in the optimal-type blind signature scheme was modified so that it can combine with threshold signature, which leads to an effective threshold blind signature scheme based on elliptic curve cryptography, it has the following securities: strong verifiability, nonrepudiation, unforgeability, blindness and robustness, and also takes advantage of characteristics of elliptic curve such as higher security and shorter key, as well as lower computational complexity compared with the previous schemes. ©2010 IEEE.

As trust management can address the new security challenges in pervasive computing environments, we present our pervasive trust model TM-RMRP which is composed of input factors and trust evaluation. With the model presented, anonymous entities can collaborate with trustful parties without central security managers. To reduce or even avoid inappropriate or inaccurate recommendations, we introduce the concept of recommendation trust and propose a recommendation mechanism of rewards and punishments based on this concept to identify more reliable recommendations. From the simulation results, the mechanism is proved to be applicable in pervasive computing environments. © 2010 IEEE.

Continuous Implicit Authentication (CIA) provides a imperceptible and passive validation in a whole process of operating the mobile devices. In this paper, we describe users' behavioral patterns through the build-in sensors of smartphones, and apply them to our authentication system. The current work is mainly implemented in a controlled experimental environment. We prove the effectiveness of the implicit authentication method in the natural environment through the analysis of only the touch screen process and the entire process of the user using the mobile phone. We focus on the multi-class strategy in CIA, in which a classifier has to recognize the "owner"of a series of operations from identity banks. To extract temporal domain and space domain features and enhance the classifier's discriminative power, our system utilizes Resnet with Squeeze-and-Excitation incorporating Attention blocks and Additive Angular Margin Loss. We evaluate our system both in our dataset and BrainRun dataset, and the accuracies of distinguish the correct identity achieves are 96.94% and 87.11% respectively. Specially, with the continuous data in BrainRun, the result is generated from behaviors during 5 s in a more interactive game. © 2021 ACM.

With the improvement of the status of mobile phones and other mobile terminals in life, the privacy protection of mobile phones is still a big problem. Aiming at the Android system, the mobile terminal operating system with the largest share today, this paper proposes a widget intention analysis method to solve the problem of how to judge the user's operation intention in privacy protection. This intention analysis method uses MobilenetV3 to extract image information, BiLSTM to extract text information, then constructs joint features together, and uses deep learning technology to realize intention analysis of widgets. Through comparative experiments, our method improves the detection accuracy and reduces the training time for the existing methods. © 2021 ACM.
