Searchable encryption for secure cloud storage

compuer security

Due to major increase in use of cloud storage by IT firm companies there is also increase the interest of stealing data from storage. There are so many methods to prevent the data from attacker but it increases the complexities of using the storage. The third party or the vendor may sell the data to some competitor for money so the data is not in safe hand on cloud. Also searchable symmetric encryption (SSE) is method to prevent from colludes but as security it growing tight the search complexity increases. As from survey we can develop a new method which is based on attributes rather key which provides more security and will be less time consuming to other existing methods. Third party storage is not as trusted as own so there must be some secure scheme or policy which protects data on other storage platform. Sahai and Water [1] find a better technique for securing data on vendor by encrypting the users credential and attaching it with the cipher-text so only person which can pass the access pattern can access the data from storage. Also there are other work done on this methods but protecting the credential is the main difficult task as access pattern may leak and if it is done nothing will be private. Identity based encryption [3] for securing the cloud storage and searching the data over it is now a trending scheme in cloud storage.
