主　　题：Blockchain(BC) merkle tree using ethereum(MTuE) multi-tenant environment(MTE) homomorphic encryption(HE) ciphertext policy attribute-based encryption(CP-ABE) 

摘      要：This research paper puts emphasis on using cloud computing with Blockchain(BC)to improve the security and privacy in a *** security of data is not guaranteed as there is always a risk of leakage of users’*** can be used in a multi-tenant cloud environment(MTCE)to improve the security of data,as it is a decentralized *** is saved in unaltered ***,Blockchain is not owned by a single *** encryption process can be done using a Homomorphic encryption(HE)algorithm along with hashing technique,hereby allowing computations on encrypted data without the need for *** research paper is composed of four objectives:Analysis of cloud security using Blockchain technology;Exceptional scenario of Blockchain architecture in an enterprise-level MTCE;Implementation of cipher-text policy attribute-based encryption(CPABE)algorithm;Implementation of Merkle tree using Ethereum(MTuE)in a Multi-tenant *** of these four objectives,the main focus is on the implementation of CP-ABE ***-ABE parameters are proposed for different levels of *** levels include inner tenant,outer tenant,Inner-Outer-Tenant,Inner-Outer-External-Tenant,Outer-Inner-Tenant,External-Outer-Inner-Tenant and the parameters such as token,private key,public key,access tree,message,attribute set,node-level,cipher-text,salting which will help in providing better security using CP-ABE algorithm in a multitenant environment(MTE)where tenants can be provided with different levels of security and achieved 92 percentage of authenticity and access-control of the data.
