Authors: Wu Yan Fang , Huang Zheng , Wen Qiao Yan
Published: September 2012

Since the introduction of the ring learning with errors (R-LWE) by Lyubashevsky, Peikert and Regev, many efficient and secure applications were founded in cryptography. In this paper, we mainly present an efficient public-key encryption scheme based on the R-LWE assumption. It is very simple to describe and analyze. As well as it can achieve security against certain key-dependent message (KDM) attacks. Namely, this efficient encryption scheme can securely encrypt its own secret key. The security of this scheme follows from the already proven hardness of the R-LWE problem since the R-LWE assumption is reducible to worst-case problems on the ideal lattice. Besides, the scheme enjoys a high level efficiency and low cost since the operations of the scheme are very simple and fast. The cost of both the encryption and decryption is only polylog(n) bit per message symbol.

In order to achieve the real-time requirement of H.264 decoding, we modify and optimize the decoding modules and codes, respectively. Firstly, we analyze the number of operations for various modules using assembly code, and then use direct memory access (DMA) to carry out the parallelism between algorithm execution and data movement. Finally, we make use of two buffer groups (BG) as parallel decoding mechanism of broadcast transformation. Experimental results demonstrate that the play rate can reach above 25 fps as using QCIF video. According to some tests, a real-time H.264 BP decoding can be achieved with a 600 MHz DSP.
Reversible Data Hiding Considering Shifting Direction and Human Visual Sensitivity
Authors: Wu Han Yan , Li Yan Wei , Chen Jean Ne , Hong Wien
Published: September 2012

In view of the technique “A New Histogram Modification Based Reversible Data Hiding Algorithm Considering the Human Visual System” by Jung et al., some modifications have been made on the parts of the causal window and the pixel overflow/underflow in present study. In Jung et al.’s method, the number of reference pixel was obtained based on a causal window so that the prediction value, the just noticeable difference (JND) and others can be determined. However, the causal window used in Jung et al.’s method may reduce the prediction accuracy. In this paper, the modifications on two parts are proposed to turn around this situation. First, the causal window is narrowed to decrease the number of reference pixels so that the prediction accuracy can be enhanced. Second, in dealing with possible pixel underflow or overflow, only the pixels that will definitely underflow or overflow, are modified. Using such modifications both the payload and the image quality can be improved. It is shown by experiments that our modifications not only increase payload but also maintain image quality effectively.
A Location Map Reduced Reversible Data Hiding Method Using Prediction Error Modification
Authors: Li Yan Wei , Wu Mei Chen , Chen Tung Shou , Hong Wien
Published: September 2012

We propose a reversible data hiding technique to improve Hong and Chen’s (2010) method. Hong and Chen divide the cover image into pixel group, and use reference pixels to predict other pixel values. Data are then embedded by modifying the prediction errors. However, when solving the overflow and underflow problems, they employ a location map to record the position of saturated pixels, and these pixels will not be used to carry data. In their method, if the image has a plenty of saturated pixels, the payload is decreased significantly because a lot of saturated pixels will not joint the embedment. We improve Hong and Chen’s method such that the saturated pixels can be used to carry data. The positions of these saturated pixels are then recorded in a location map, and the location map is embedded together with the secret data. The experimental results illustrate that the proposed method has better payload, will providing a comparable image quality.

An Optimized Method for Access of LOBs in Database Management Systems
Authors: Liang Jun Jie , Zhan Wei
Published: September 2012

This paper researches methods used by relational database management systems to manage LOBs. It attempts to use LOB slave table methods to optimize and advance the storage structures of large objects as well as optimize the redo and undo log mechanisms to increase LOB access efficiency. For changes in slave table data, it effectively prevents the redo log from being written into the LOB database, while diminishing the amount of changes being recording within the undo journal. This improves the writing speed of the log, thus improving the access efficiency and speed of the slave table record. At the same time, this optimized log mechanism also ensures the correct recovery of data after a system crash. Tests have shown that the optimized LOB access efficiency is slightly better than Oracle’s.

Published: September 2012

Multimedia applications bring demands on broadband real-time data transfer, which needs resource reservation protocol (RSVP) helps to satisfy. However, handover processes bring delay, and existing authentication mechanism makes it further worse. Based on Pareto distribution patterns of mobile station communication traffic, proposed a trust transfer mechanism to execute pre-anticipated trust transfer and shorten the delay. It means that the dominant minority correspondent nodes designed in the VIP address books are informed about trust context messages, such as the information of handover, AAA, QoS, before anticipated handover. With the trust transfer mechanism, the simplification can be made to the authentication mechanism, which divides trust handover sequencing into several paralleled parts and budges some steps between stations. Thereby cut processes on each node by processes simultaneously carrying. Simulation with a modified NS2 platform showed that when time setforward equals 0.2, the delay is reduced by about 19.12% and the resource possession of RSVP is mitigated by 30.13%.

Published: September 2012

The communication and sharing of visual media show a strong cross-platform feature. Massive images are shown on various devices with different resolution. Automatic image cropping, usually used to change the resolution of image, often discards important content in the image. This paper proposed a novel adaptive photo cropping method. The main idea is exploiting the characteristics of photograph aesthetics in photograph works. The algorithm infers the intention of photographer according to the depth of field in the image. The effects brought out by the focus and unfocus are utilized to exact importance information of the image. So, the method can be more satisfied with the subjective evaluation. And, it has advantage in term of computational speed. Experimentations are presented to demonstrate the validity of proposed method.

The Research for the Least Energy Cost Optimization Algorithm Based on the LEACH Protocol
Authors: Xia Zhong Lin , Zhou Xin Lian
Published: September 2012

The paper proposes a new least energy cost optimization algorithm for the deficiency of the low energy adaptive clustering hierarchy (LEACH) protocol. In the perspective of the energy, the algorithm uses the least energy cost to decide whether the network clustering is on the optimal state, meanwhile the status of the cluster energy cost is imported to conduct clustering gradually towards minimizing energy consumption. Based on the theoretic analysis of the energy consumption, it is proved to have a longer network lifecycle which performs better than the LEACH.
