Presenting an efficient an‎d secure edge-based searchable attribute-based encryption scheme in IOT

مهندسي فناوري اطلاعات

Todays, with the expansion of big data an‎d the increasing importance of data mining in businesses, a large amount of information is stored in the cloud. One of the challenges faced by businesses is that most of their data is sensitive data; As a result, their confidentiality an‎d privacy should be maintained. For this purpose, it is necessary to store encrypted data in the cloud. When an organization stores its encrypted data on the cloud, it must still use them; So, for retrive an‎d use of this data, this encryption must be searchable. Also, due to the limited resources of users, the process of obtaining data should not have a lot of overhead. In this research, we have presented a attribute-based searchable encryption scheme that outsources the encryption an‎d decryption process with the help of an edge server in a two-step manner an‎d with the guarantee of data confidentiality, an‎d in addition By using attribute-based access control, it provides the possibility of controlling user access. The proposed scheme is based on the index list method an‎d supports multi-keyword search. By using keyword clustering in a subject-oriented way, the mentioned scheme reduces the search operation time an‎d is safe against collusion attack an‎d chosen keyword attack.
