“…In order to solve the problem of the lack of heterogeneity and dynamics of cloud application services with a single executor, and the difficulty of dealing with the security threats of unknown vulnerabilities and backdoors, a mimic cloud service architecture was proposed.In this architecture, the application services provided by the cloud platform were constructed into a service package based on mimic defense technology, so that the application services had the endogenous security features and robustness brought by mimic structure.At the same time, two key mimic cloud services operating mechanism，policy scheduling and adjudication mechanism were discussed.The experimental results and analysis show that the mimic cloud service obtains better security and its response time delay can be reduced by reducing the performance difference of the executor.…”

Identity-based puncturable signature scheme by Dongmei YANG, Yue CHEN, Jianghong WEI, Xuexian HU

“…To overcome the shortcomings of available forward-secure identity-based signature （IBS） scheme in terms of actual practicability and secret key update efficiency， the notion of identity-based puncturable signature （IBPS） scheme was proposed based on the idea of puncturable public-key encryption scheme.Specifically， the syntax and security notion of IBPS were given， and then a concrete IBPS scheme was constructed based on Bloom filter.Under the computational Diffie-Hellman assumption， the proposed scheme achieved the existential unforgeability in the random oracle model.The performance analysis and implementation results demonstrate that， compared with traditional forward-secure IBS schemes， the proposed scheme provides more practical fine-grained forward secrecy， and has higher efficiency of secret key update.…”

Random routing defense method based on deep deterministic policy gradient by Xiaoyu XU, Hao HU, Hongqi ZHANG, Yuling LIU

“…To solve the problem of the existing routing shuffling defenses, such as too coarse data flow splitting granularity, poor protection effect on legitimate QoS and the security against eavesdropping attacks needed to be improved, a random routing defense method based on DDPG was proposed.INT was used to monitor and obtain the network state in real time, DDPG algorithm was used to generate random routing scheme considering both security and QoS requirements, random routing scheme was implemented with programmable switch under P4 framework to realize real-time routing shuffling with packet level granularity.Experiment results show that compared with other typical routing shuffling defense methods, the security and QoS protection effect of the proposed method are improved.…”

Design of efficient anonymous identity authentication protocol for lightweight IoT devices by Zhenyu WANG, Yang GUO, Shaoqing LI, Shen HOU, Ding DENG

“…Aiming at the problem that complex security primitives in existing schemes were not suitable for resource-constrained IoT devices, a lightweight efficient anonymous identity authentication protocol for IoT devices was designed based on physical unclonable function (PUF).Through the formal security model and ProVerif tool, it was proved that the protocol satisfies 13 security properties such as information confidentiality, integrity, un-traceability, and forward/backward secrecy.Compared with existing relevant protocols, the computing overhead of the protocol on the device side and the server side is 0.468 ms and 0.072 ms respectively, and the device storage and communication overheads are 256 bit and 896 bit respectively, which is highly suitable for lightweight IoT devices with limited resources.…”

Dynamic accumulators-based authenticated group key management scheme for heterogeneous wireless sensor network by Xiao-rui ZHONG, Chun-guang MA

“…Witnesses of a dynamic accumulator (DA) can ensure whether an object has been accumulated.On the basis of this,node membership in a cluster was verified and a novel authenticated group key management protocol was proposed,which supports node revocation and addition.In order to establish a group key for a cluster,each member provides their assigned number to join accumulation.DAAG can not only guarantee the confidentiality of witnesses,but also keep non-members from calculating novel group keys by binding witness with group key update.The security and performance analyses show that DAAG is resistant against replay attack,forgery attack and collusion attack,and can provide forward security and backward security.…”

Ring-based efficient batch authentication and group key agreement protocol with anonymity in Internet of vehicles by Haibo ZHANG, Kai LAN, Zhou CHEN, Ruyan WANG, Can ZOU, Mingyue WANG

“…Aiming at the problem that the current batch authentication and key agreement protocol were relied on semi-trusted road side unit (RSU) and were not suitable for key update in large-scale Internet of vehicles (IoV), a ring-based efficient batch authentication and group key agreement protocol with anonymity in IoV was proposed.The anonymity was ensured by the pseudonym mechanism.The authentication key pairs were constructed by the chaotic map, and the batch authentication for many vehicles was quickly completed by a small number of bilinear maps.The joining and leaving of vehicles in large-scale IoV scenario were fully considered, a ring session group was efficiently constructed by using the semi-group property of chaotic maps, and a group key establishment and update mechanism suitable for large-scale vehicles was designed.In addition, a pseudonym update mechanism and an anonymous tracing mechanism were designed to ensure a more secure session process.At the same time, the BAN logic model was used to prove the semantic security of the protocol.The security analysis and simulation results show that the proposed protocol has multiple security attributes and certain efficiency advantages.…”

Verifiable attribute-based searchable encryption scheme based on blockchain by Xixi YAN, Xiaohan YUAN, Yongli TANG, Yanli CHEN

“…For the problem that the shared decryption key lacks of fine-grained access control and the search results lacks of correctness verification under one-to-many search model,a verifiable attribute-based searchable encryption scheme based on blockchain was proposed.The ciphertext policy attribute-based encryption mechanism was used on the shared key to achieve fine-grained access control.Ethereum blockchain technology was combined to solve the problem of incorrect search results returned by the semi-honest and curious cloud server model,so it could prompt both the cloud server and the user to follow the rules of the contract honestly and achieved service-payment fairness between the user and the cloud server in the pay-per-use cloud environment.In addition,based on the irreversible modification of the blockchain,the cloud server was guaranteed to receive the service fee,and the user was assured to obtain the correct retrieval results without additional verification which reduced the computational overhead of the user.The security analysis shows that the scheme satisfies the semantic security against adaptive chosen keyword attack and can protect the privacy of users and the security of data.The performance comparison and experimental results show that the scheme has certain optimizations in security index generation,search token generation,retrieval efficiency and transaction quantity,so it is more suitable for one-to-many search scenarios such as smart medical.…”
