An improved Huffman coding with encryption for Radio Data System (RDS) for smart transportation

As the development of Radio Data System (RDS) technology and its applications are getting more and more attention and promotion, people concern their personal privacy and communication efficiency, and therefore compression and encryption technologies are being more important for transferring RDS data. Unlike most of the current approaches which contain two stages, compression and encryption, we proposed a new algorithm called Swapped Huffman Table (SHT) based on Huffman algorithm to realise compression and encryption in a single process. In this paper, a good performance for both compression and encryption is obtained and a possible application of RDS with the proposed algorithm in smart transportation is illustrated.     

试述用异或算法来实现计算机软件外壳加密的程序

计算机软件产品是一种知识密集的特殊产品,生产一个软件产品需要大量的人力物力,生产难度大,成本高,周期慢。但是,软件产品的复制却是相当的容易。这就导致了非法复制、盗版软件之风的泛滥。加密是目前保护知识产权的一种有效方式。但任何加密软件都可能被破译、我们不能因噎废食。加密与解密,是矛和盾的关系,要想防止被解读,必须提高加密技术。本文利用异或算法对文件的关键代码节来实现了这种加密,防止通过使用Soft-ice或者其他的调试软件来对程序进行反汇编,阻止分析源程序,以此来实现对软件的保护。     

Secure smart grid communications and information integration based on digital watermarking in wireless sensor networks

As more and more wireless sensor nodes and networks are employed to acquire and transmit the state information of power equipment in smart grid, we are in urgent need of some viable security solutions to ensure secure smart grid communications. Conventional information security solutions, such as encryption/decryption, digital signature and so forth, are not applicable to wireless sensor networks in smart grid any longer, where bulk messages need to be exchanged continuously. The reason is that these cryptographic solutions will account for a large portion of the extremely limited resources on sensor nodes. In this article, a security solution based on digital watermarking is adopted to achieve the secure communications for wireless sensor networks in smart grid by data and entity authentications at a low cost of operation. Our solution consists of a secure framework of digital watermarking, and two digital watermarking algorithms based on alternating electric current and time window, respectively. Both watermarking algorithms are composed of watermark generation, embedding and detection. The simulation experiments are provided to verify the correctness and practicability of our watermarking algorithms. Additionally, a new cloud-based architecture for the information integration of smart grid is proposed on the basis of our security solutions.     

Boundary conditions for turnover intentions: exploratory evidence from China,Jordan, Turkey,and the United States

Over the past decade, employability has been presented by its advocates as the solution to employment uncertainty, and by its critics as a management rhetoric possessing little relevance to the experiences of most workers. This article suggests that while employability has failed to develop into a key research area, a deeper probing of its message is warranted. In particular, it is suggested that employability may have resonance with employees as workers rather than as employees of their immediate employing organization. This demands a slightly different approach to studying employability than some other related phenomena such as employee commitment, which has resonance only in relation to the employing organization. In adopting a social identity approach, the significance of the employability message is shown to lie not only in employees' willingness to disassociate from their existing work groups and pursue individual mobility, but also in its capacity to undermine workers' collective responses to grievances and unwanted organizational changes. A future research agenda is presented which highlights the need to address recent attempts to develop employability expectations among graduate career entrants, and for a closer critical engagement with management writings that attempt to justify the unnecessary espousal of the self-development message.
