| 1 | Anonymous handover authentication protocol for mobile wireless networks with conditional privacy preservation显示文摘With the development of the wireless communication technology and the popularity of mobile devices, the mobile wireless network(MWN) has been widely used in our daily life. Through the access point(AP), users could access the Internet anytime and anywhere using their mobile devices. Therefore, MWNs can bring much convenience to us. Due to the limitation of AP's coverage, the seamless handover frequently occurs in practical applications. How to guarantee the user's privacy and security and identify the real identity when he/she brings harm to the system becomes very challenging. To achieve such goals, many anonymous handover authentication(AHA) protocols have been proposed in the last several years. However, most of them have high computation costs because mobile nodes need to carry out the bilinear pairing operations or the hash-to-point operations. Besides, most of them cannot satisfy some critical requirements, such as non-traceability and perfect forward secrecy. In this paper, we first outline the security requirements of AHA protocols, and then propose a new AHA protocol to eliminate weaknesses existing in previous AHA protocols. Based on the hardness of two famous mathematical problems, we demonstrate that the proposed AHA protocol is secure against different kinds of attacks and can meet a variety of security requirements. It can be seen from the details of implementations that the proposed AHA protocol also has much less computation cost than three latest AHA protocols. | Debiao HE Ding WANG Qi XIE Kefei CHEN | 2017 | Science China(Information Sciences)2017，60，5： | 7 |
| 2 | A provable-secure and practical two-party distributed signing protocol for SM2 signature algorithm显示文摘Mobile devices are widely used for data access,communications and storage.However,storing a private key for signature and other cryptographic usage on a single mobile device can be challenging,due to its computational limitations.Thus,a number of(t,n)threshold secret sharing schemes designed to minimize private key from leakage have been proposed in the literature.However,existing schemes generally suffer from key reconstruction attack.In this paper,we propose an efficient and secure two-party distributed signing protocol for the SM2 signature algorithm.The latter has been mandated by the Chinese government for all electronic commerce applications.The proposed protocol separates the private key to storage on two devices and can generate a valid signature without the need to reconstruct the entire private key.We prove that our protocol is secure under nonstandard assumption.Then,we implement our protocol using MIRACL Cryptographic SDK to demonstrate that the protocol can be deployed in practice to prevent key disclosure. | Yudi ZHANG Debiao HE Mingwu ZHANG Kim-Kwang Raymond CHOO | 2020 | Frontiers of Computer Science2020，14，3： | 6 |
| 3 | SecBCS: a secure and privacy-preserving blockchain-based crowdsourcing system显示文摘A robust and scalable crowd management infrastructure is crucial in addressing operational challenges when deploying high-density sensors and actuators in a smart city. While crowdsourcing is widely used in crowd management, conventional solutions, such as Upwork and Amazon Mechanical Turk, generally depend on a trusted third-party platform. There exist several potential security concerns(e.g., sensitive leakage, single point of failure and unfair judgment) in such a centralized paradigm. Hence, a recent trend in crowdsourcing is to leverage blockchain(a decentralized ledger technology) to address some of the existing limitations. A small number of blockchain-based crowdsourcing systems(BCSs) with incentive mechanisms have been proposed in the literature, but they are generally not designed with security in mind. Thus, we study the security and privacy requirements of a secure BCS and propose a concrete solution(i.e., SecBCS)with a prototype implementation based on JUICE. | Chao LIN Debiao HE Sherali ZEADALLY Neeraj KUMAR Kim-Kwang Raymond CHOO | 2020 | Science China(Information Sciences)2020，63，3： | 4 |
| 4 | Efficient privacy-preserving user authentication scheme with forward secrecy for industry 4.0显示文摘Industry 4.0,which combines information technology,network and industrial production,is expected to have a tremendous impact on our daily lives.In such a complex and security-critical system with resource-constrained sensor nodes,the design of a secure user authentication scheme for preventing real-time data from unauthorized access is full of challenges,and the main crux lies in how to realize the important property of forward secrecy.Existing schemes either fail to achieve forward secrecy or achieve forward secrecy with high computation cost on sensor nodes.Besides,they often fail to conform to the development trend of industry 4.0 systems where a cloud center is necessary to help intelligent decision-making and alleviate computation and storage pressure.Therefore,in this paper,we propose an efficient privacy-preserving user authentication scheme with forward secrecy for industry 4.0,and formally prove its security in the random oracle model.Compared with previous schemes,it has three advantages:(1)all eleven state-of-the-art criteria are achieved;(2)its computation cost on sensor nodes is comparable to those insecure schemes that employ only symmetric cryptographic algorithms,and is superior to those that also use asymmetric cryptographic algorithms;(3)it takes the advantage of the computation and storage capabilities of the cloud center to achieve user anonymity and the resistance to offline dictionary attack without performing any asymmetric cryptographic algorithms on gateways.Our computation cost on gateways is the smallest among all state-of-the-art relevant schemes for comparison. | Chenyu WANG Ding WANG Guoai XU Debiao HE | 2022 | Science China(Information Sciences)2022，65，1： | 2 |

| 11 | One-to-many authentication for access control in mobile pay-TV systems显示文摘In traditional authentication schemes for access control in mobile pay-TV systems, one-to-one delivery is used, i.e., one authentication message per request is delivered from a head-end system(HES) to a subscriber. The performance of one-to-one delivery for authentication is not satisfactory as it requires frequent operations which results in high bandwidth consumption. To address this issue, one-to-many authentication for access control in mobile pay-TV systems was developed. It requires only one broadcasted authentication message from a HES to subscribers if there are many requests for the same service in a short period of time.However, later it was revealed that the one-to-many authentication scheme was vulnerable to an impersonation attack, i.e., an attacker without any secret key could not only impersonate the mobile set(MS) to the HES but also impersonate the HES to the MS. Then, a new scheme has been recently introduced for secure operations of one-to-many authentication. However, as shown in this paper, the recent work for one-to-many authentication is still vulnerable to the impersonation attack. To mitigate this attack, in this paper, a new scheme for one-tomany authentication using bilinear pairing is proposed that eliminates security weaknesses in the previous work.Results obtained depict that the new improved scheme in this paper provides better performance in terms of computation and communication overheads. | Debiao HE Neeraj KUMAR Han SHEN Jong-Hyouk LEE | 2016 | Science China(Information Sciences)2016，59，5： | 1 |

| 14 | An efficient data aggregation scheme with local differential privacy in smart grid显示文摘By integrating the traditional power grid with information and communication technology, smart grid achieves dependable, efficient, and flexible grid data processing. The smart meters deployed on the user side of the smart grid collect the users' power usage data on a regular basis and upload it to the control center to complete the smart grid data acquisition. The control center can evaluate the supply and demand of the power grid through aggregated data from users and then dynamically adjust the power supply and price, etc. However, since the grid data collected from users may disclose the user's electricity usage habits and daily activities, privacy concern has become a critical issue in smart grid data aggregation. Most of the existing privacy-preserving data collection schemes for smart grid adopt homomorphic encryption or randomization techniques which are either impractical because of the high computation overhead or unrealistic for requiring a trusted third party. | Na Gai Kaiping Xue Bin Zhu Jiayu Yang Jianqing Liu Debiao He | 2022 | Digital Communications and Networks2022，8，3： | 1 |
