Simple Matrix encryption scheme with variable ciphertext length by Zhong WANG, Yiliang HAN

“…Multivariable public key cryptography is one of the reliable candidates for anti-quantum cryptography.The Simple Matrix scheme is constructed using the operations between three matrices.An improved version of the Simple Matrix scheme was proposed.It is constructed by using two flat matrices with random quadratic polynomials,so that the rank attacks is infeasible for the new scheme,and the algebraic attacks breaks the system is at least as hard as solving a set of random quadratic equations.The new scheme will improve the proportion of ciphertext and plaintext to 2 times or more,break the fixed proportion of ciphertext and plaintext,so that it has a flexible proportion to adapt to different needs.…”

Analysis and improvement of sensor networks security protocol by YAN Li-li1, PENG Dai-yuan1, GAO Yue-xiang1

“…A suit of security protocols for sensor networks was presented by A.Perrig.The security of the protocols was analyzed,and then one attack had been found in the two-party key agreement protocol that a false request message from an intruder.In that case,the intruder impersonates the node and creates false requests.An improved protocol to this attack was proposed.The security of improved protocol was analyzed by the extended strand spaces,where two main security properties,authenticity and confidentiality,were checked.And the analysis proves the correctness of the protocol.The extended strand spaces also gives a practical base for further application of strand spaces in analyzing complicated protocols.…”

A playback speech detection algorithm based on log inverse Mel-frequency spectral coefficient by Lang LIN, Rangding WANG, Diqun YAN, Can LI

“…The popularity and portability of high-fidelity audio recording equipment and playback equipment poses a serious challenge for speaker recognition systems against playback attacks.Based on the differences between the original speech and the playback speech in high frequency region,the algorithm reversed the Mel-filter bank in Mel-frequency cepstral coefficient (MFCC) calculation,and the coefficients before the DCT were used as the features of the algorithm.SVM was utilized as the classifier.Experimental results show that this algorithm can effectively detect the playback speech.In addition,the algorithm is integrated into the GMM-UBM speaker recognition system,which significantly improves the systems’ capability of resisting the playback attack.…”

Study on electronic evidence acquisition and analysis method over Windows logs by Xiao-mei DONG, Xu-dong LIU, Xiao-hua LI, Ya-jie FEI

“…In order to collect logs in real time,two methods to acquire Windows logs in real time were proposed respectively according to the two types of log file formats.Based on acquiring logs,an approach for correlating log files with atomic attack functions was proposed.After the correlation,atomic attack functions can be analyzed instead of log files,which can greatly decrease the time of analysis.A time based log correlation and event reconstruction method was proposed to reconstruct the computer criminal scenarios.Experimental results show that log evidences can be acquired and the crime process can be reconstructed effectively.…”

Implementation architecture of mimic security defense based on SDN by Zhen-peng WANG, Hong-chao HU, Guo-zhen CHENG, Chuan-hao ZHANG

“…To deal with the attacks employing unknown security vulnerabilities or backdoors which are difficult for traditional defense techniques to eliminate,mimic security defense (MSD) that employs “dynamic,heterogeneity,redundancy (DHR)” mechanism can increase the difficulty and cost of attack and uncertainty of system so as to improve network security.Based on the software defined networking (SDN),an implementation architecture of MSD was proposed.First,diverse functional equivalent variants for the protected target were constructed,then leverage the rich programmability and flexibility of SDN to realize the dynamic scheduling and decision-making functions on SDN controller.Simulation and experimental results prove the availability and the intrusion tolerant ability of the architecture.…”

Lightweight and secure vehicle track verification scheme via broadcast communication channels by Zhiqiang NING, Yuanyuan WANG, Chi ZHANG, Lingbo WEI, Nenghai YU, Yue HAO

“…In intelligent transportation systems, it is crucial for smart vehicles to broadcast real-time vehicle track messages to coordinate driving decisions and ensure driving safety.However, attackers can manipulate vehicle tracks by modifying timestamps or manipulating signal frequencies, posing a threat to security.To address this problem, a lightweight vehicle track verification scheme was proposed, utilizing the broadcast communication channels to achieve secure verification of vehicle tracks without any special hardware support.Without time synchronization, each verifier calculated the time interval between the reception time of the message and the sending timestamp.Spatial position constraint equations are formulated by combining these time intervals between any two verifiers, effectively defending against timestamp forgery attacks.Additionally, each verifier calculates the Doppler frequency shift between the arrival frequency and the scheduled transmit frequency.Velocity vector constraint equations were formulated by combining these frequency shifts between any two verifiers, providing defense against carrier frequency manipulation attacks.Formal analysis shows that increasing the number of verifiers improves the accuracy of the proposed verification scheme.Experimental results in a real-world environment further validate that the proposed verification scheme exhibits the best performance when the number of verifiers is set to 3.Compared to the existing solution, the proposed verification scheme has a higher accuracy, lower false rejection rate, and lower false acceptance rate when validating true vehicle track and false vehicle track separately.…”

Computational assessment of winglet-induced variations in pressure coefficients on NACA 4418 aircraft wings by Md. Abdullah, Mohammad Zoynal Abedin

“…The results reveal that the pressure coefficient becomes high at 20%C, then decreases to a minimum value at 45%C and then rises gradually up to again a higher value at 80%C for the angles of attack of − 4° and 0° at three airfoil velocity. However, for the angles of attack of 4°, 8°, 12°, 16°, 20° and 24°, the pressure coefficient becomes minimum at 20%C, then gradually increases and finally becomes maximum at 80%C for three airfoil velocities. …”

Anonymous trust management scheme of VANET based on attribute signature by Min XIAO, Faying MAO, Yonghong HUANG, Yunfei CAO

“…Trust management mechanisms can solve the authenticity assessment problem of messages and establish trust between communication entities in the VANET.However, current trust management schemes lack an effective privacy protection mechanism, leading to privacy concerns for vehicles when binding their identity with their trust level.Based on the anonymity of attribute-based signature, an anonymous trust management scheme was proposed for VANET.The trust level of the vehicle was maintained by the trusted authority.The trust level of vehicles and the current time were taken as the attribute identity set of the vehicle, so as to realize the binding of the anonymous vehicle identity with its trust level, which could provide the privacy protection of vehicles.In addition, the timely update of attribute signature private key could resist false reputation attack and the trust level of the vehicle could be verified anonymously while the attribute signature was verified.Furthermore, the pseudonym was used to hide the real identity of the vehicle, enabling only the trusted authority could parse the real identity of vehicles from the pseudonym to update their trust level, and providing legal and secure tracking of the malicious vehicle identity vehicle.Under the general group model, the attribute-based signature scheme is proven to satisfy the security of unforgerability.The security analysis further shows that the scheme protects the identity and location privacy of vehicles, enables only the trusted authority to legally track malicious vehicles, resists false reputation attacks, ensures communication integrity, and resists replay attacks.Performance analysis confirms that the proposed scheme has better computation and communication efficiency than existing schemes.…”
