ASSURED Searchable Encryption

This component enables the efficient search over a collection of encrypted documents or files based on keys generated in the context of ABE or ABAC without the ability to decrypt them. Basically, SE acts as a data management technique that allows the data owners to store and manage their data at a third-party, untrusted cloud server and allows the data user to delegate search functionality to the cloud server to retrieve that data. As traditional implementations cannot provide data confidentiality, in ASSURED context is used Blockchain technology to host the Dynamic Searchable Encryption.
