Enhancement of the homomorphism encryption based mechanism by solving the integrity problems effectively on multi keyword search in cloud computing

Abstract

Cloud computing gives part of advantages to endeavors to offload their information and software services to cloud administrations by saving them lot of money that must be spent on foundation setup cost. Despite that, while offloading the information privacy and protection is a vital concern. Correspondingly for example when the emergency clinics and medicinal services association transfer their patient's subtleties to cloud and when the information is included, it will influence the protection of the patients. So privacy is a vital concern while offloading the information to cloud. Most of solutions for privacy depend on encryption and information to be offloaded is encoded and put away in cloud. Lots of encryption techniques like cryptography, symmetric key etc. methods are used for encrypting the information before uploading to cloud. However, the reaction in this encryption system is that, the encrypted information isn't structure preserving and it is not suitable for ranking or searching. To solve the complications of this searching and ranking due to disordering a homomorphism encryption based mechanism is proposed but this solution also suffers from the problem of integrity attacks on result. So this paper discussed the enhancement of the homomorphism encryption based mechanism by solving the integrity problems effectively.
