CC-MRSJ:Cache Conscious Star Join Algorithm on Hadoop Platform by Guoliang Zhou, Yongli Zhu, Guilan Wang

“…A cache-conscious MapReduce star join algorithm was presented,each column of fact table was separately stored,and dimension table was divided into several column families according to dimension hierarchy.Fact table foreign key column and corresponding dimension table was co-location storage,thus reducing data movement in the join process.CC-MRSJ consists of two phases:firstly each foreign key column and the corresponding dimension table were joined; then the intermediate results were joined and random accessed measure columns,and so got the final result.CC-MRSJ read only the data needed,and cache utilization is high,so it has good cache conscious feature; it also takes advantage of late materialization,avoiding unnecessary data access and movement.CC-MRSJ has higher performance comparing to hive system based on SSB datasets.…”

Simulation of transmission characteristics of oceanic wireless optical communication systems based on orbital angular momentum multiplexing with space-time coding by Xiaoli YIN, Tong ZHENG, Zhiwen SUN, Zhaoyuan ZHANG

“…In order to mitigate the crosstalk caused by oceanic turbulence in the underwater wireless orbital angular momentum multiplexing optical communication system, the application of space-time coding technology in the system was studied.Based on Rytov approximation, the covariance method and interpolation method were used to simulate correlated random phase screens and then the influence of time-varying oceanic turbulence channel on orbital angular momentum signal was studied.The transmission characteristics of orbital angular momentum multiplexing optical communication system with space-time coding was analyzed by simulation.The phase structure function of the time-varying phase screens and the detection probability distribution of the beam carrying the orbital angular momentum through the time-varying simulation channel were in line with theoretical expectations.The simulation results show that the space-time coding technology can effectively mitigate the influence of ocean turbulence on the system bit error rate.…”

Massive unsourced multiple access scheme based on block sequence codebook and compressed sensing by Jing ZHANG, Lin MA, Chulong LIANG, Hongxu GAO

“…A massive unsourced multiple access scheme based on block sequence codebook and compressed sensing was proposed for sporadic burst scenario in massive machine type communication (mMTC).Firstly, a large-capacity spreading codebook generation scheme was designed according to a specific shift pattern, thus the codebook space was expanded.Secondly, the sparse structure of uplink signal was combined with multi-carrier technology to support overlapping transmission of multi-user data on some subcarriers, thus the spectral efficiency was improved.Finally, a multi-carrier CS-MUD model was established, and a group orthogonal matching pursuit algorithm based on codebook sequence blocks was designed to achieve the joint detection of active users and their uplink data.Simulation results show that the proposed scheme can effectively reduce the bit error rate of massive random access.…”

Certificate-based hybrid encryption scheme in the standard model by KANG Li, TANG Xiao-hu, FAN Jia

“…For construction a public cryptosystem that requiring fewer infrastructures than public key infrastructure（PKI）,a certificate-based public-key encryption（CBE） scheme was proposed by Gentry.In CBE scheme,a certification was signed by a third part on an applicant’s public key or identity and sent to the applicant,the applicant saved it and used it as partial private key（decryption key）.A receiver wanted to decrypt a ciphertext,the certification was needed from the third party and his own public-private keys,so CBE combined the best aspects of identity-based encryption（implicit cer-tification） and public key encryption（no escrow）.A new efficient certificate-based hybrid encryption scheme with short public key was proposed,which based on Gentry’s identity-based encryption scheme,the new scheme can be proved re-sistance adaptive chosen ciphertext attack in the standard model（without random oracle）.…”

Mobility model detection method based on birth and death model in DTN environment by ENGGuang-hong D, AOWan-hua C, HANGJian Z, HENGXiong C, ENGLi F

“…A mobility model detection method based on birth and death model (MMD-BDM) in DTN environment was proposed.It first computed the connected channel capacity of sampling times according to the data traffic during the data transfer process,and then constructed the time varying intercommunication metrics at local,which composed of channel capacity between local node and others.Based on these,the connection birth and death mode of nodes based on connected edges was deduced,and then the birth and death features of the connected nodes was analyzed to detect the mobility model,which used to improve the routing strategy during the packages deliver process.Ultimately,the mobility model detection method was put into use in spray and wait routing (SWR) method and random network coding routing (RNCR) method to experiment,the simulation results show that,it can improve the opportunity routing performance of the data deliver rate and transfer latency in DTN environment.…”

Statistical ineffective fault analysis of the lightweight authenticated cipher algorithm Saturnin-Short by Wei LI, Chun LIU, Dawu GU, Wenqian SUN, Jianning GAO, Mengyang QIN

“…On the random single byte-oriented fault model and the assumption of ciphertext-only attack, a statistical ineffective fault analysis of the Saturnin-Short cipher was proposed.The analysis combined the statistical distribution with the ineffective analysis, and discussed the difference between intermediate states before and after fault injections.A variety of dual distinguishers was designed, such as the probabilistic symmetric Chi-square-maximum likelihood estimate, and harmonic mean-Hamming weight.It only required at least 1 097 ineffective faults to recover the 256 bit secret key with a success rate of at least 99%.The experimental results show that the proposed distinguishers can not only decrease fault injections, but also reduce the attacking time and complexities.Therefore, the Saturnin-Short cipher cannot resist against the statistical ineffective fault analysis.It provides an important reference for the security analysis of other lightweight authenticated ciphers.…”

Impossible statistical fault analysis of the PRIDE lightweight cryptosystem by Wei LI, Wenqian SUN, Dawu GU, Ailin ZHANG, Yunhua WEN

“…To analyze the implementation security of the PRIDE lightweight cryptosystem proposed at CRYPTO in 2014, a novel method of impossible statistical fault analysis on the ciphertext-only attack assumption was proposed.Furthermore, new distinguishers were designed, such as the Chi-square goodness-of-fit test-Hamming weight, and Chi-square goodness-of-fit test-maximum likelihood estimation.The proposed method had a random nibble-oriented fault model, and combined the statistical distribution states with the impossible relationship.On the difference among the intermediate states before and after the fault injections, at least 432 faults were required to recover the 128 bit secret key of PRIDE with a reliability of at least 99%.The experimental analysis demonstrates that the proposed method can not only reduce injected faults and latency, but also increase the accuracy.The results provide a vital reference for exploring the implementation security of lightweight cryptosystems.…”
