Authentication scheme for multi-cloud environment based on smart card by Sen ZHAO, Qingqing GAN, Xiaoming WANG, Fang YU

“…To solve the problem of the access keys stored in a smart card increasing linearly with the number of registered clouds without third party participated in authentication,an authentication scheme was proposed for multi-cloud environment based on smart card.In the proposed scheme,the authentication was realized between user and multiple clouds without third party participation when the smart card only stored two access key.Thus the storage cost of smart card was reduced effectively.Because there was no public key cryptography,the authentication messages was generated by using XOR homomorphic function and Hash function,thus the computational cost of the smart card and the cloud servers was reduced effectively.Moreover,the proposed scheme also didn’t need to store any user’s information on the cloud servers,thereby reducing the storage and management costs of the cloud servers.The security analysis and the performance analysis show that the proposed scheme is able to resist multiple attacks,which is secure and efficient.…”

LEO Satellite Internet of Things Access Technology Based on Beamforming by Xuxu XIE, Xiaojin DING, Tao HONG, Gengxin ZHANG

“…The integration of terrestrial communication and satellite communication for internet of things (IoT) is the inevitable trend of the development of wireless communication network, to achieve the vision of the connection of everything.As a supplement to terrestrial IoT, satellite IoT can make up the fl aws of terrestrial IoT.However, with the expansion of IoT scale, it will be diffi cult for satellites to meet the communication needs of increasing number of IoT terminals, because the problem of limited satellite load will become increasingly prominent.Multiple-input multiple-output (MIMO) technology is the key technology of terrestrial 5G, and also an important research direction of satellite communication in the future 6G.The beamforming(BF) technology was introduced in MIMO into the low earth orbit (LEO) satellite based IoT, to made full use of spatial resources and signifi cantly improved system capacity.In view of the implementation conditions of BF technology and the characteristics of satellite IoT, several related issues were discussed, included channel model, BF criterions, load balancing access technology of one satellite and cooperative BF access technology of several satellites.…”
