Network resource pricing strategy based on SDN framework by Bin ZHUGE, Yihang QI, Hanwen FU, Weiming WANG

“…A network resource pricing strategy based on SDN framework was proposed to solve the problem of resource overload and network congestion caused by resource requests in the network.Firstly,the user’s needs and consumption patterns were analyzed,and the resource transaction model was determined.Secondly,combined with the spot consumption model and plan consumption,the reservation mechanism under the resource dynamic pricing strategy model was determined.Finally,according to the proposed resource pricing strategy,the resource price was simulated,the results show that by stimulating the user to reserve resources in advance and combining the trust degree and consumption habits of each user with corresponding preferential prices,it is possible to effectively avoid the users from obtaining network resources in a centralized manner.…”

Asymmetric watermarking based on Contourlet transform and subspace projection by HE Mi, CHENG Li-zhi

“…For the copyright protection of the digital image,a new asymmetric watermarking method of feature subspace projection based on Contourlet transform was presented.Embedding matrix（private key） and detecting matrix（public key） were constructed differently,where embedding matrix was kept secretly while detecting matrix was public.At the same time,the embedding matrix was independent on the host images.Robust subspace was obtained by Contourlet transformation.Using the embedding matrix,the arbitrary watermarking was embedded in the robust subspace.The de-tection function was constructed to detect whether an image had watermarking or not.The proposed method has good security,high detection probability and low false alarm probability.The stimulation shows that the proposed method is robust to many attacks.…”

Boolean-chaos-based physical random number generator by Qiqi ZHANG, Jianguo ZHANG, Pu LI, Yanqiang GUO, Yuncai WANG

“…A novel method for generating physical random numbers using Boolean-chaos as the entropy source was proposed.An autonomous Boolean network (ABN) without self-feedback was constructed by using two-input logic gates,and its dynamic characteristics were analyzed.Based on this,a 15-node ABN circuit was implemented to successfully generate Boolean-chaos with a bandwidth of ~680 MHz and a min-entropy around 1.By implementing the entropy source and the entropy extraction circuit on a single FPGA,the physical random number generation with a real-time rate of 100 Mbit/s was finally achieved.The NIST SP800-22 and DIEHARD randomness test results demonstrate that the obtained random sequences by the method successfully pass all tests.This indicates the random numbers has good random statistical characteristics.…”

TD algorithm based on double-layer fuzzy partitioning by Xiang MU, Quan LIU, Qi-ming FU, Hong-kun SUN, Xin ZHOU

“…When dealing with the continuous space problems,the traditional Q-iteration algorithms based on lookup-table or function approximation converge slowly and are diff lt to get a continuous policy.To overcome the above weak-nesses,an on-policy TD algorithm named DFP-OPTD was proposed based on double-layer fuzzy partitioning and its convergence was proved.The first layer of fuzzy partitioning was applied for state space,the second layer of fuzzy parti-tioning was applied for action space,and Q-value functions were computed by the combination of the two layer fuzzy partitioning.Based on the Q-value function,the consequent parameters of fuzzy rules were updated by gradient descent method.Applying DFP-OPTD on two classical reinforcement learning problems,experimental results show that the algo-rithm not only can be used to get a continuous action policy,but also has a better convergence performance.…”

Construction of quantum BCH code based on cyclotomic coset by Lijuan XING, Zhuo LI

“…Quantum-error-correcting code can overcome quantum decoherence efficiently, which is the key technology to realize quantum computers.A series of quantum BCH code was proposed based on classical codes.First, a general way of well-chosen cyclotomic coset was introduced.A sufficient condition was given to calculate the number of elements in cyclotomic coset.Then, a series of quantum BCH (Bose-Chaudhuri-Hocquenghem) code over finite field F_q was constructed by CSS (Calderbank-Shor-Steane) construction and Steane construction.The results were extended to finite field F_q² with Hermitian construction.Compared with the results in literature,the range of introduced cyclotomic coset is more wide, and the new quantum BCH code has higher dimensions and better lower bounds on minimum distances.Furthermore, a family of quantum maximum distance separable (quantum MDS) code over any finite fields is constructed.…”
