Secured Group Data Sharing Over Cloud by Using Key Aggregate and Searchable Techniques

Patil Snehal

Abstract: Cloud computing has given the users the accessibility to deploy number of files to the centralized cloud and share those with number of users. The flexibility of cloud computing always comes with the hurdles of security concerns. The data owner always needs to encrypt the files before uploading and it must decrypt before end users. This system needs secure storage of keys, but as files gets increased in number keys management becomes complex. We have proposed the system called as (KASE). The system proposes aggregate key for file sharing in groups and searchable encryption. We have observed that to create trapdoors manually for specific files it becomes very tedious and hence we have applied the TF-IDF technique to avoid manual job.
