PRIVACY AND OWNER AUTHERISATION FRAMEWORK TO MANAGE KEYS

computer engineering

ABSTRACT The number of encryption keys increases due to limit of web app users get exceeds. Outsourcing keys to the professional password managers is an attractive trend. Traditional outsourcing scenarios are not capable to meet the security requirements for outsourcing keys such as, privacy & confidentiality of keys, privacy on attribute ties to keys at the time of search. In proposed system, SC-PRE scheme is utilized. It combines two approaches such as, Proxy Re-encryption (PRE) and Hidden Vector Encryption (HVE). It encrypts key tuple similar to normal data encryption. The proposed cloudKeyBank framework achieved three security requirements for outsourcing of keys such as, confidentiality of key privacy, attributes of search ties with key and owner controllable authorization on shared keys. Bloom filter is space-efficient probabilistic data structure designed to specify whether an element is present or not in the set. It is rapid and memory efficient strategy which we contribute in our proposed work. It can save search space and time of searching.
