INTRODUCTION:

Combination of existingtechnologies includes gridcomputing and virtualizationAllows to pay only for resourcesusedProvides large scale controlled

sharing and interoperation amongresources

CLOUD COMPUTING:

Involves delivering hosted services

It is a service not a product

Here shared resources ,software andinformation are provided to

computers

CLOUD COMPUTING

SERVICES:

Services divided into three categories:

Infrastructure as-a-service-Platform virtualization environment

-Service with raw storage and networking

-Resources used are fully outsourced service Platform-as-a-service

-Sustains cloud applications

-Facilitates deployment of applications and reducescomplexity of buying

-Managing both hardware and software

Software-as-a-service-Eliminate the need of installment

-Simplify the maintenance and support

ADVANCEMENTS:

EASE OF USE:

-Location and device independence

SCALABILITY:

-Controls infrastructure

REDUCED RISK:

-Maintenance is easier

RELIABILITY:

-Improves when multiple redundant sites areused

COST:

-Purported to lower barriers to entry

-Used for frequent intensive computing tasks

Existing system:-Composed of different local systems and members

from

multiple environments causes data insecurity

- In existing system there is no system to find data

security

- Openness and flexibility brings complexity and

reduces trust degree

Proposed system:-Improve the secure and dependable computing in

cloud

-Integrate the Trusted Computing Platform(TCP)which is based on Trusted Platform Module

-The TCP will be used in authentication

IMPLEMENTATION STEPS:

The following modules areimplemented:

User Registration

Master key and Session keygeneration

Dynamic system Configuration

Authentication

Trusted Platform Module (TPM)

Database Management

Cloud Server

USER REGISTRATION:

-registers login details, system configuration

details , phone number.

MASTER KEY AND SESSION KEY GENERATION:

-when client registers with server, TPM generates

Master key and whenever he logins itgenerates Session key

DYNAMIC SYSTEM CONFIGURATION

AUTHENTICATION:-obtained System Configuration details are

compared with already registered system

configuration details.

TRUSTED PLATFORM MODULE(TPM):

-checks the logged in details and createsa session key.

DATABASE MANAGEMENT:

-contains all details of the clients in itsnetwork.

CLOUD SERVER:

-gets the user queries, matches with theindex data present in it and serves the

client.

ACTIVITY DIAGRAM:

Register the client system

imformation in server

login to the server and wait

for server autentication

Server checks the clients

configuration details if it

matches

client can upload and

download file from server

CONCLUSION:

Hence the security of cloud computingenvironment is analyzed.

To achieve trusted computing

requirements for the cloud computingusing trusted computing technology.

Thus TCP provides user authentication

and security services.
