AES Enabled Private Information Retrieval Scheme for Location Based Queries

Lothe Ashwini Bhaskar, Apare Ravindra S

Abstract: Various issues are embarrassing while using Location Base Search, Out of this preserving privacy and protecting content for Location Base queries is the in wireless concern. User fires question to get location base information but do not wish to expose his coordinate to the server and at the server will only send data to the validate user. For preserving privacy, user hides its coordinate through encryption and send to the server, information at a server is secured since a malicious user can only decrypt the block of data, accept by Private Information Retrieval (PIR) with the encryption key acquired in the previous stage. In earlier work ElGamal encryption scheme is used for encryption has some disadvantage like a need for randomness and its slower speed. Another potential problem of the ElGamal system is that message expansion by a factor of two takes place during encryption. To overcome problems as quoted earlier, Advanced Encryption Scheme (AES) is proposed here for the encryption of data. Recommended scheme is distinguished by using time and speed parameter
