Chaining & counter-based block cipher mode for authentication
Published 2009-01-01“…For raising the operation efficiency of block cipher algorithms,a fast authentication mode based on chaining & counter(CCTR) was put forward;and its security was proved.Its speed was about 30% faster than that of authentication modes in common use(for example,CBC-MAC).The dependence test results accord with the demands.The CCTR mode is complete;its degree of avalanche effect is about 0.999 3;its degree of strict avalanche criterion is 0.992 or so.The frequency test results indicate that the output generated by the CCTR mode had uniformity.The binary matrix rank,Run,spectral,non-overlapping template matching,overlapping template matching,Maurer’s universal statistical test,Lempel-Ziv compression,linear complexity,serial,approximate entropy,cumulative sums,random excursions and random excursions variant tests results fulfilled the requirements all.Therefore,the CCTR mode has good pseudo-randomness,which the security of CCTR mode is verified by way of statistical evaluation.…”

Improved SOR signal detection algorithm in massive MIMO-TRDMA systems
Published 2021-10-01“…In the massive multi-input multi-output time-reversal division multiple access (MIMO-TRDMA) systems, the traditional linear minimum mean square error (MMSE) algorithm achieved approximately the best performance.However, the matrix inversion of the MMSE algorithm was too complicated to ensure real-time processing of signal detection.To solve this problem, an improved successive over-relaxation (SOR) signal detection optimization algorithm was proposed.The proposed algorithm reasonably upgraded the solution of linear equations to prevent the complicated calculation of matrix inversion.Meanwhile, the steepest descent idea was used to provide an effective search direction for the SOR signal detection algorithm, achieving a rapid convergence rate and stronger inspection performance.The simulation results show that the proposed algorithm has the similar best performance with fewer update times compared with the traditional MMSE algorithm, and the calculation complexity is reduced from O(M<sup>3</sup>)to O(<sup>2</sup>).…”

Physical-layer network coding in k-users MIMO-Y two-way relay channels
Published 2015-10-01“…In order to exchange information among k users using the technology of physical-layer network coding in the multiple input multiple output Y two-way relay channels,the GSA-GSA scheme was proposed,using the technology of general signal alignment during the uplink and the downlink.The signals were exchanged between every source node align in a transformed subspace,rather than the direct subspace.This was realized by jointly designing the precoding matrices at all source nodes and the processing matrix at the relay.The constraints of the number of sending and receiving antennas and the sum rate of proposed scheme were analyzed.In simulation,it can figure out that the proposed scheme needs fewer antennas in the whole system and can improve the achievable system sum rate under the same SNR and degrees of freedom.…”

RASP based Web security detection method
Published 2020-11-01“…At present,the traditional Web security detection methods act on the input and output of the program,which can not prevent malicious code entering the program after being distorted and confused,and it is difficult to meet the new requirements of Web application security protection.Based on the in-depth analysis of the risk of traditional data flow monitoring methods,combined with the technical characteristics of rasp,a Web security detection method based on rasp was proposed.The rasp probe was embedded in the parameters of authority discrimination function,system command execution function and database operation function in Web application,and the change of data flow was detected in real-time at the code interpreter level.This method was implemented based on Java language.It was proved in the laboratory that this method is better than the traditional Web security detection method in accuracy and detection time.Finally,the deployment and application scenarios of this method were analyzed and proposed.…”

Improved method of compensating non-reciprocal interference in adaptive TDD MIMO-OFDM systems
Published 2009-01-01“…In a time division duplex(TDD) system,the channel state information could be easily obtained at the trans-mitter side without feedback due to channel reciprocity and it could be used to increase dramatically the spectral effi-ciency of a multi-input multi-output(MIMO) system.However,the interference structure between transmission directions did not necessarily correlate at all.In such a case,the downlink modulation/coding parameters based on the uplink meas-urements might lead to excessively high frame error rates(FER).Therefore,a simple closed-loop feedback method of in-terference adaptation was proposed,which made the transmit-side estimated interference be able to track the instantane-ous receive-side interference dynamically,and its performance in adaptive TDD MIMO-OFDM systems with HARQ was studied.Simulation results show that the tracking performance is well and the target FER requirement can be guaranteed.…”
