Method for constructing function correspondence between firmware based on candidate function group by Ruiqing XIAO, Yuefei ZHU, Shengli LIU, Bin LU

“…Due to the characteristics of firmware, traditional binary comparison methods are prone to mismatches during the propagation of the matching function.Aiming at the problem that the matching function propagation algorithm is not ideal, a method for constructing function correspondence based on candidate function groups was designed, and the concept of function matching in n layer local network is supplemented.Then, three candidate function group construction strategies and candidate function group matching methods are proposed, and the time overhead were analyzed.Finally, a prototype system was implemented based on the method and compared with Bindiff.Through random sampling and manual check, 86.04% of the matching results of the proposed method are consistent with Bindiff matching results, while 11.3% can correct Bindiff matching errors.…”

Scalability Optimization of Virtualization Based Botnet Emulation Platform by Li Ruan, Bo Lin, Limin Xiao

“…Botnet emulation,a new technology to investigate Botnet characteristics,gains increasing focus.The practical virtualization based Botnet emulation platform is few and lacks support of rapid deployment,multiple virtualization,specific features of the Botnet like Botnets' circadian random shutdown and starting,and high scalability which will greatly influence the Botnet propagation emulation effect.A Botnet emulation system and its scalability improvement technologies were introduced.Experiments show that the memory performance optimization and CPU performance optimization reduce more than 77% of host memory per virtual machine,the maximum virtual machines one physical machine can starts up increase from 15 to 43; the host CPU utility is deduced from 100% to 20% when the vCPU's performance is restricted to 100 000.…”

Public key based key distribution scheme for wireless sensor networks by HUANG Jie1, HUANG Bei1

“…Since key pre-distribution schemes based on symmetric key can not completely solve security problems of keys distribution in WSN,a new public key based key distribution scheme was proposed.In the scheme,public key set was generated by an initial public key set and a hash function in base station.Each sensor device was pre-distributed one public/private pair-wise key from public key set and a public key subset from the initial public keys set.Owing to uniqueness of private key,not only the communication security problems could be improved for WSN.but also the sensor-memory cost could be decreased.With the theorem of random-graph theory,the connectivity and scalability were illustrated.The results showed that the scheme was superior to the traditional key pre-distribution schemes.…”

Security authentication protocol based on elliptic curve cryptography and cookie information for terminal of IoT by Jie ZHAO, Huarong ZHANG

“…For the security problem of terminal devices accessing to the network server in internet of things（IoT），an identity authentication protocol was presented based on elliptic curve cryptography（ECC）and cookie information for internet of things terminal.Firstly，the protocol used user identity information，server private key，random number and expiration time of cookie to form a cookie file.Then，it was encrypted with ECC and stored in the smart terminal.In authentication phase，the mutual authentication was achieved by comparing the security parameters calculated by cookie information.Performance analysis shows that it can resist many kinds of attacks and provide high security，low computation and low communication cost，which was suitable for the terminal devices of limited resources in internet of things.…”

Investigating Lexical Progression through Lexical Diversity Metrics in a Corpus of French L3 by Paula Lissón, Nicolas Ballier

“…Our case study (24 learners, 3 productions per learner in the course of 3 months) deals with a semi-longitudinal corpus, where each of the productions is supposed to be more complex than the previous one. Random forests (Breiman, 2001; Hothorn et al., 2019) are used in order to see whether lexical diversity metric scores capture enough vocabulary diversity progression to predict the production wave. …”

Application of FMICW technology based on stagger algorithm in automotive radar by Yuanhui ZHANG, Jian YANG, Junjiang ZHU, Xiaolu LI, Yuchen HE

“…The problem of spurious spectral peaks produced by the traditional method of using a single switching frequency in automotive FMICW radar was focused by the proposed scheme.The system accuracy depended on the previously estimated range if a bandpass filter was utilized to eliminate the spurious spectral peaks,and the noise floor could be too high to achieve the required dynamic detection range if the random interrupted sequence method was utilized.A stagger algorithm based on multiple switching frequencies was used,in which the spurious peaks from the frequency domain could be removed by minimizing each frequency position on multiple spectrums.Simulation results show that the proposed method is close to the equivalent FMCW radar detection performance,and is good in multiple targets scenario.…”

Multi-type spectrum resources joint distribution algorithm based on guaranteed QoS by Ling LIU, Yongju XIAN, Jia ZHU

“…The definition of the spectrum availability in terms of static spectrum,semi-static spectrum and dynamic spectrum and the definition of service requirement index based on M-LWDF QoS definition were proposed.A spectrum allocation method and a redistribution method combined with spectrum availability and subscriber requirement were presented.The main idea of the method is that subscriber requirement and availability of spectrum resource are quantified,and then spectrum resources are allocated to subscribers by a one-to-one mapping based on their quantified values in the same sequence.Compared with the random distribution scheme and the dynamic scheme following static allocation,simulation results show that the scheme presented can obviously improve system performance in average number of failure distribution and average total data rate.…”

Key-exposure resilient integrity auditing scheme with encrypted data deduplication by Xiangsong ZHANG, Chen LI, Zhenhua LIU

“…For the problems of key-exposure,encrypted data duplication and integrity auditing in cloud data storage,a public auditing scheme was proposed to support key update and encrypted data deduplication.Utilizing Bloom filters,the proposed scheme could achieve client-side deduplication,and guaranteed that the key exposure in one time period didn’t effect the users’ private key in other time periods.The proposed scheme could solve the conflict between key-exposure resilient and encrypted data deduplication in public auditing scheme for the first time.Security analysis indicates that the proposed scheme is strong key-exposure resilient,confidentiality,detectability,and unforgeability of authentication tags and tokens under the computation Diffie-Hellman hardness assumption in the random oracle model.…”
