Use of Diffie Hellman Key Exchange for Information Transmission and File Integrity Monitoring in Cloud

today's computing era,there has arisen an immense requirement for secure and trusted security frameworks/models in cloud computing.These models allow the cloud service provider to establish a trusted bond among clients,which is the prime requisite for cloud e-businesses nowadays. Keeping this orientation in mind,we have proposed a comprehensive security framework which provides extra layer of security to the information transmitted among client and server ends & also sustains the information integrity at both terminals.It provides the data security during storage at cloud server . This incorporates confidentiality,authentication and integrity of the involved information among client-server terminals.Numerous cryptographic algorithms have been used to apply in the implemented tool. Diffie- Hellman key exchange scheme has been applied in this research work.
