To access the data anytime from anywhere in an easy way and as an advantage of service storage at very low cost, organizations are keeping their important data at cloud space. For the establishment of trust between service provider and data user, we have used cryptography. For providing the security a method of cryptography is encryption scheme. Further encryption schemes are also have different types as per requirement and one of them is searchable encryption. Researchers have worked upon development of effective schemes for searchable encryption. Here we have explored some techniques of cryptography like B-tree and CKRSA for the enhancement of security level which leads to trust. We have uses the cloud platform Microsoft Azure for the searching upon encrypted clod data.
