Certificateless public key cryptography based provable data possession scheme in edge environment
Published 2022-07-01“…In the edge environment, data transmission to the cloud needs to pass through a new entity, the edge node, which makes the data security problem more complicated, the confidentiality and integrity of data are difficult to be guaranteed, and the traditional provable data possession scheme is not suitable for the edge environment with a large number of devices.Based on this, a certificateless public key cryptography based provable data possession scheme was proposed for the edge environment, combining the online/offline signature idea, where the user device only needed to perform light computation when uploading data in the case of semi-trusted edge nodes, leaving the rest of the computation to be performed in the offline phase.The scheme used edge nodes for auditing work while supporting auditing in different storage states, as well as privacy protection and other features.The security analysis shows that the proposed scheme is proven to be secure by being able to effectively combat three types of adversary attacks under a stochastic prediction model.Experimental comparisons with other schemes show that the proposed scheme has lowest time overhead.…”

Nove lincidence matrix differential power analysis for resisting ghost peak
Published 2023-04-01“…At present, differential power analysis (DPA) is one of the most important threats to the security of block ciphers in chips.When the collected power trace is insufficient, DPA is vulnerable to ghost peak caused by the difference mean value generated by the wrong key.Based on DPA, a incidence matrix differential power analysis (IMDPA) was proposed which could effectively resist ghost peak.The prediction difference mean matrix was constructed to avoid the influence of the non leaking interval on the key guessing of the leaking interval by using the weak correlation of the guessing key in the non leaking interval.The proposed IMDPA was tested in different leak intervals of AES-128 algorithm.The results show that compared with traditional DPA, IMDPA requires less (up to 85%) power trace to guess the correct key.At the same time, the key guessing efficiency of AES-128 under the implementation of protective measures by IMDPA still has obvious advantages.In order to further verify the universality of IMDPA in block ciphers, experimental verification is conducted on SM4 algorithm.Compared with traditional DPA, IMDPA requires less (up to 87.5%) power traces to guess the correct key.…”

FAULT DIAGNOSIS NEW METHOD OF ROLLING BEARING BASED ON ADAPTIVE REDUNDANT LIFTING SCHEME PACKET
Published 2015-01-01“…Aiming at feature identification of weak signal for rolling bearing fault,an adaptive redundant lifting scheme packet( ARLSP) diagnostic method of undecimated operation was proposed to solve the faults distortion that caused by traditional wavelet packet or lifting wavelet transform using sample operation.ARLSP was based on the principle of lifting scheme.Initial undecimated prediction and update operator were calculated by Lagrange interpolating subdivision,and then constructed an ARLSP decomposition and reconstruction algorithm.Simulation signals were tried out by denoising and anti frequency aliasing,results show that ARLSP method was superior to the traditional wavelet packet in denoising capabilities,and there are no frequency aliasing.Moreover,taking an experiment on an asynchronous motor,the vibration signals of the rolling bearings 6205 under conditions of no fault,the inner ring fault,outer ring fault and rolling fault were measured.ARLSP method has been successfully used to extract characteristic frequency and frequency multiplication for various faults,and has got a higher diagnostic accuracy than traditional wavelet packet.…”
