We present a novel audio information hiding scheme based on robust message authentication code (rMAC). By combining coefficient quantization based information hiding scheme with rMAC and chaotic encryption, proposed scheme can ensure the content integrity and the confidentiality of the embedded audio as well as secret communication. Experimental results show that our scheme provides highly robust authentication against content preserving degradations. When 30 % noise added into the transporting message, 92.50 % audio communication can also succeed. © 2013 Springer-Verlag.

Most multicast data origin authentication schemes work under the fixed parameters without taking the problem of changeable network environment into account. However, the network conditions will obviously influence the efficiency of a protocol such as the time delay and the overhead. So adjusting the parameters adaptively to achieve the ideal state with the dynamic network is necessary. To achieve a high authentication rate and adapt to the changeable and unstable network environment, we proposed a multicast data origin authentication protocol which is adaptive depending on the packet error rates as well as the time delay, and is robust against the packet loss and injection. Our model can estimate a more appropriate packet error rate and make the time delay lower according to the feedback values got from the receivers using the Markov chain so that it can be adaptive. This strategy is especially efficient in terms of not only the adaptation of dynamic network but also the shortcut of overhead and delay. © Springer-Verlag Berlin Heidelberg 2013.

Layered SSD/HDD hybrid storage system has been widely used. However, most traditional designs are performance oriented, and not optimized for SSD lifespan. In this paper, SSD lifespan oriented layered model and cache algorithm are proposed. To decrease SSD wear rate, HDD-RAM switch tunnel is appended to the traditional layered hybrid structure. Cache window size is considered in cache algorithm to filter data, avoiding unnecessary cache cost. Results show optimized designs significantly reduced erase times on SSD, and slightly influenced original performance. © 2015 Taylor & Francis Group, London.

In their nature, wireless sensor nodes are resource restrained, such as low power capabilities and small memory. These limitations inevitably affect secure energy-efficient wireless sensor networks protocols in such way that some cryptographic algorithms such as asymmetric algorithms are not convenient to be used in wireless sensor nodes. In this paper, based on perturbation-based efficient confidentiality preserving scheme and Energy-Efficient Secure Pattern Based Data Aggregation for Wireless Sensor Networks scheme, we achieve higher energy-efficiency by using pattern-codes approach to avoid energy wastage due to sending redundant data to cluster-heads. Symmetric cryptographic algorithms such as perturbation algorithm used are more convenient to wireless sensors by providing high data privacy and confidentiality as well. © 2013 IEEE.

Tag Authentication is an essential issue in RFID system which is wildly applied in many areas. Compared to the per-tag-based authentication, the batch-mode authentication has better performance for complex applications. However, many existing batch authentication protocols suffer from security and privacy threats, low efficiency problem or high communication and computation cost. In order to solve these problems better, we propose a new RFID batch authentication protocol. In this protocol, tags are grouped and each key in one group shares the same group key. The connection between the group key and the tag's own key is fully utilized to construct our batch authentication protocol. Meanwhile, based on the proposed batch authentication protocol, we propose a group tags ownership transfer protocol which also supports the tag authorisation recovery. Compared with previous schemes, our scheme achieves stronger security and higher efficiency. In the side of security and privacy, our scheme meets most requirements, such as tag information privacy, forward/backward security, resistance against reply, tracking, and Dos attacks. Then we carry on the theoretical analysis and implement the simulation experiment. Both of them indicate that the performance of our scheme is much efficient than other authentication schemes. Particularly, the simulation results show that the run time of the whole authentication process in our scheme is decreased 20% at least compared with the other existing schemes.

The Secure Channel Free Public Key Encryption with Keyword Search (SCF-PEKS) scheme, which enables one to search for the encrypted keywords without leaking the privacy. In this paper, we point out the inefficiency of SCF-PEKS scheme and construct a new Located Secure Channel Free Public Key Encryption with Keyword Search (LSCF-PEKS) scheme to improve the efficiency. Furthermore, the LSCF-PEKS scheme is applied to implement cloud storage-oriented secure information gateway. At last, a bidding system is implemented as a case of this scenario.
