Optimization method for attribute-based cryptographic access control in mobile cloud computing by Jian LIU, Ming XIAN, Huimei WANG, Hong RONG

“…For the problem of secure data sharing and access control in mobile cloud,the drawback of traditional cryptographic access control schemes was deeply analyzed.Considering the truth that mobile devices were usually equipped with limited resources,an optimized attribute-based cryptographic access control scheme was proposed in this study.In the proposed scheme,a third party proxy was introduced into the system model,and the two-layer encryption method was applied.Combining traditional attribute-based encryption (ABE) algorithm with multi-secret sharing and split measurement of ABE encryption,the scheme could greatly reduce the cost of mobile users in terms of data publish and access management.Theoretical and experimental analysis shows that the contribution can well meet the requirements of mobile cloud in terms of security,computational complexity and communication cost,which means that it is promising for future applications.…”

Community field-centric trust-based access control model by Zhi-qiang YAO, Jin-bo XIONG, Jian-feng MA, Qi LI, Xi-meng LIU

“…Context-aware interaction and cooperation among agents provids digital community services.However,it also brings new problems of secure access.A novel community field-centric trust-based access control model (referred to as the CTBAC) was developed by thoroughly considering both the trust level of agent and the cooperation among agents inside and outside of community fields in digital commun ty.There are two novel ingredients.Firstly,a community field was established in terms of agent’s own contexts and trust certificate.Thus,the trust level could be dynamically adjusted based on the sessions.Secondly,the activation and use of access control permissions according to the match relationship between the trust level of agents and trust threshold.The proposed CTBAC model was compared to several access control models and its effectiveness in both dynamic permission control and security protection was demonstrated.…”

ID-based server-aided verification signature scheme with strong unforgeability by Xiao-dong YANG, Miao-miao YANG, Guo-juan GAO, Ya-nan LI, Xiao-yong LU, Cai-fen WANG

“…Most identity-based signature schemes in the standard model are existentially unforgeable,which cannot prevent adversaries from forging valid signatures on messages that have previously been signed.However,signature verification algorithms of ID-based signature schemes in the standard model require expensive bilinear pairing operations.In order to overcome the shortcomings of the existing ID-based signature schemes such as strong security assumption and high computation cost，a strongly unforgeable ID-based server-aided verification signature scheme was presented.This scheme was proven to be secure under collusion attacks,adaptive chosen identity and message attacks in the standard model.Analysis results show that the proposed scheme effectively reduces computation cost of pairing operation,and it greatly reduces computational complexity of signature verification algorithm.The proposed scheme is more efficient than the existing ID-based signature schemes.…”

“…To address the security problem of the vulnerability of the authentication methods of traditional physical access control systems,a mimic defense authentication method was designed based on the principle of mimic defense technique and its dynamic heterogeneous redundant architecture (DHR),using mobile 2D code as the interface and dynamic password as the core.First,the actuator pool of the authentication server was constructed.Then,a central controller consisting of functional modules such as input distribution agent,selector and voter was used to dynamically schedule heterogeneous redundant actuators from the actuator pool.Finally,a multimode ruling on the heterogeneous redundant actuator output to determine the authentication result was made by the voter.The experimental results show that the proposed authentication method has higher security and reliability compared to the traditional physical access control system authentication method,and at the same time,it can be used in combination with other authentication methods.…”

“…Key agreement scheme of vehicle ad hoc networks (VANET) determines the privacy and security against user identity-based attacks,such as spoofing attack.The existing work updates the group shared key at a fixed frequency,which increases the processing latency of the key updates and the encryption and decryption of group communication.A reinforcement learning based dynamic key agreement scheme was proposed to enable the group cluster head to optimize the key update frequency and key length.This scheme optimizes the calculation latency of encryption and decryption based on the number of surrounding vehicles,the previous key update records without the knowledge of the traffic flow model and the access-driven cache attack model.Simulation results show that this scheme reduces the transmission delay of the communication overhead and the computational latency of encryption and decryption,and improves the security of the group key compared with the benchmark scheme.…”
