The limited computing resources, the disconnection network, the classification requirements of identity authentication, the requirement of trust transfer and cross identity authentication, the bi-directional identity authentication, the security delegation and the simple privacy protection etc are all these unsolved problems. In this paper, a new novel ubiquitous computing identity authentication mechanism, named UCIAMdess, is presented. It is based on D-S Evidence Theory and extended SPKI/SDSI. D-S Evidence Theory is used in UCIAMdess to compute the trust value from the ubiquitous computing environment to the principal or between the different ubiquitous computing environments. SPKI-based authorization is expanded by adding the trust certificate in UCIAMdess to solve above problems in the ubiquitous computing environments. The identity authentication mechanism and the algorithm of certificate reduction are given in the paper to solve the multi-levels trust-correlative identity authentication problems. The performance analyses show that UCIAMdess is a suitable security mechanism in solving the complex ubiquitous computing problems.展开更多

Therefore, the security of smartphones is the most crucial issue to illegal users who cannot access legal users’ privacy information. This paper studies identity authentication using user action. This scheme does not rely on the password or biometric identification. It checks user identity just by user action features. We utilize sensors installed in smartphones and collect their data when the user waves the phone. We collect these data, process them and feed them into neural networks to realize identity recognition. We invited 13 participants and collected about 350 samples for each person. The sampling frequency is set at 200 Hz, and DenseNet is chosen as the neural network to validate system performance. The result shows that the neural network can effectively recognize user identity and achieve an authentication accuracy of 96.69 percent.展开更多

This paper proposes a private user data protection mechanism in Trust Zone to avoid such risks. We add corresponding modules to both the secure world and the normal world and authenticate the identity of CA to prevent illegal access to private user data. Then we analyze the system security, and perform validity and performance tests.The results show that this method can perform effective identity recognition and control of CA to protect the security of private user data. After adding authentication modules, the data operation time of system increases by about0.16 s, an acceptable price to pay for the improved security.展开更多

文摘To address identity forgery and privacy leakage in Internet of vehicles(loV)within intelligent transportation systems,we propose an efficient cross-domain identity authentication(IA)scheme based on blockchain and certificateless cryptography.However,existing IA schemes often suffer from high computational overhead,limited scalability,or inadequate support for cross-domain scenarios.First,a distributed authentication architecture is designed,and an offchain storage mechanism combining blockchain and distributed hash table(DHT)to reduce storage costs.Second,a key generation scheme based on certificateless cryptography is designed to address key escrow problem.Third,a conditional privacy protection mechanism is proposed to achieve both anonymity and traceability of vehicle identities.A formal privacy evaluation is provided based on k-anonymity quantifies anonymity level under realistic adversary models.Finally,performance evaluations are conducted in terms of authentication delay,throughput,and success rate,demonstrating that the proposed scheme improves authentication efficiency while enhancing the system security and privacy.

文摘In the Internet of Things(IoT),a large number of devices are connected using a variety of communication technologies to ensure that they can communicate both physically and over the network.However,devices face the challenge of a single point of failure,a malicious user may forge device identity to gain access and jeopardize system security.In addition,devices collect and transmit sensitive data,and the data can be accessed or stolen by unauthorized user,leading to privacy breaches,which posed a significant risk to both the confidentiality of user information and the protection of device integrity.Therefore,in order to solve the above problems and realize the secure transmission of data,this paper proposed EBIAS,a secure and efficient blockchain-based identity authentication scheme designed for IoT devices.First,EBIAS combined the Elliptic Curve Cryptography(ECC)algorithm and the SHA-256 algorithm to achieve encrypted communication of the sensitive data.Second,EBIAS integrated blockchain to tackle the single point of failure and ensure the integrity of the sensitive data.Finally,we performed security analysis and conducted sufficient experiment.The analysis and experimental results demonstrate that EBIAS has certain improvements on security and performance compared with the previous schemes,which further proves the feasibility and effectiveness of EBIAS.

文摘To solve the privacy leakage and identity island problems in cross-chain interaction,we propose an anti-quantum cross-chain identity authentication approach based on dynamic group signature(DGS-AQCCIDAA)for smart education.The relay-based cross-chain model promotes interconnection in heterogeneous consortium blockchains.DGS is used as the endorsement strategy for cross-chain identity authentication.Our approach can ensure quantum security under the learning with error(LWE)and inhomogeneous small integer solution(ISIS)assumptions,and it uses non-interactive zero-knowledge proof(NIZKP)to protect user identity privacy.Our scheme has low calculation overhead and provides anonymous cross-chain identity authentication in the smart education system.

文摘As one of the essential steps to secure government data sharing,Identity Authentication(IA)plays a vital role in the processing of large data.However,the centralized IA scheme based on a trusted third party presents problems of information leakage and single point of failure,and those related to key escrow.Therefore,herein,an effective IA model based on multiattribute centers is designed.First,a private key of each attribute of a data requester is generated by the attribute authorization center.After obtaining the private key of attribute,the data requester generates a personal private key.Second,a dynamic key generation algorithm is proposed,which combines blockchain and smart contracts to periodically update the key of a data requester to prevent theft by external attackers,ensure the traceability of IA,and reduce the risk of privacy leakage.Third,the combination of blockchain and interplanetary file systems is used to store attribute field information of the data requester to further reduce the cost of blockchain information storage and improve the effectiveness of information storage.Experimental results show that the proposed model ensures the privacy and security of identity information and outperforms similar authentication models in terms of computational and communication costs.
文摘The advancement of 6G wireless communication technology has facilitated the integration of Vehicular Ad-hoc Networks(VANETs).However,the messages transmitted over the public channel in the open and dynamic VANETs are vulnerable to malicious attacks.Although numerous researchers have proposed authentication schemes to enhance the security of Vehicle-to-Vehicle(V2V)communication,most existing methodologies face two significant challenges:(1)the majority of the schemes are not lightweight enough to support realtime message interaction among vehicles;(2)the sensitive information like identity and position is at risk of being compromised.To tackle these issues,we propose a lightweight dual authentication protocol for V2V communication based on Physical Unclonable Function(PUF).The proposed scheme accomplishes dual authentication between vehicles by the combination of Zero-Knowledge Proof(ZKP)and MASK function.The security analysis proves that our scheme provides both anonymous authentication and information unlinkability.Additionally,the performance analysis demonstrates that the computation overhead of our scheme is approximately reduced 23.4% compared to the state-of-the-art schemes.The practical simulation conducted in a 6G network environment demonstrates the feasibility of 6G-based VANETs and their potential for future advancements.

文摘In Trust Zone architecture, the Trusted Application（TA） in the secure world does not certify the identity of Client Applications（CA） in the normal world that request data access, which represents a user data leakage risk. This paper proposes a private user data protection mechanism in Trust Zone to avoid such risks. We add corresponding modules to both the secure world and the normal world and authenticate the identity of CA to prevent illegal access to private user data. Then we analyze the system security, and perform validity and performance tests.The results show that this method can perform effective identity recognition and control of CA to protect the security of private user data. After adding authentication modules, the data operation time of system increases by about0.16 s, an acceptable price to pay for the improved security.

文摘Due to the rapid advancements in network technology,blockchain is being employed for distributed data storage.In the Internet of Things(IoT)scenario,different participants manage multiple blockchains located in different trust domains,which has resulted in the extensive development of cross-domain authentication techniques.However,the emergence of many attackers equipped with quantum computers has the potential to launch quantum computing attacks against cross-domain authentication schemes based on traditional cryptography,posing a significant security threat.In response to the aforementioned challenges,our paper demonstrates a post-quantum cross-domain identity authentication scheme to negotiate the session key used in the cross-chain asset exchange process.Firstly,our paper designs the hiding and recovery process of user identity index based on lattice cryptography and introduces the identity-based signature from lattice to construct a post-quantum cross-domain authentication scheme.Secondly,our paper utilizes the hashed time-locked contract to achieves the cross-chain asset exchange of blockchain nodes in different trust domains.Furthermore,the security analysis reduces the security of the identity index and signature to Learning With Errors(LWE)and Short Integer Solution(SIS)assumption,respectively,indicating that our scheme has post-quantum security.Last but not least,through comparison analysis,we display that our scheme is efficient compared with the cross-domain authentication scheme based on traditional cryptography.
