Existing system

Software as a Service (SaaS)

Platform as a Service (PaaS)

Infrastructure as a Service (IaaS)

Disadvantages

CSPs believe that Security is End-users’ Issue.

Inconsistent Network Connection Issues.

Clients have no idea or control over what happens inside a cloud.

PROPOSED SYSTEM

Data Protection as a Service (DPaaS).

Provides a common platform for masses.

Access control, logging and key management.

Auditing of data protection.

DPaaS Architecture

Activity of admin

Activity of users

Advantages

Secure execution environment.

It reduce the effort of cloud serviceproviders .

Provides a common platform formasses.

Access control, logging and keymanagement.

Modules

Cloud Computing

Trusted Platform Module

Third Party Auditor

User Module

Key management

Advanced Encryption Standard (AES).

AES-128, AES-192 and AES-256.

Each cipher encrypts and decrypts data in

blocks of 128 bits using cryptographic keys of

128-, 192- and 256-bits.

Conclusion

Protect the data of cloud users and is part

of cloud computing.

Provides complete security with the

help of access control, logging, and key

management
