In this presentation, kartik introduces cloud computing and associated trends. In his own words Kartik would like to "work with developing powerful & efficient cryptographic methods or techniques to ensure data integrity , confidentiality & anonymity among the organizations."

2. INTRODUCTION
 Cloud computing , is the practice of using a network
of remote servers hosted on the internet to store ,
manage, process data .
 emerged from distributed computing , evolved from
grid computing.
 Organizations are benefited by cloud technology by
downsizing ICT costs & incorporating multilateral
network effects.
 Cloud Service models -: pay-per-service & pay-per-
use.
 Security challenges- privacy, data leakage, identity
protection, sensitive information.
 Solution – Anonymous IDMSes.

3. INDUSTRIAL SOLUTIONS
 Industrial standards for managing centralized
& federated identities in cloud environment.
1. Open id- standard for authentication without
requiring separate ad hoc systems.
• Eliminates need for maintenance of different
identities by authentication of users.
• Provides framework.
• User may create open id account.
• Smart cards for authentication.

4. 2.SHIBBOLETH.
• Manages (SSO).
• Eliminates need for maintaining different
identities & passwords.
• Open source implementation of federated
identity based management.
3.OAuth.
• Open standard for delegating authorization.

5. Trends
o Existing solutions-:
o Anonymous authentication protocols.
• Ring signature
• Public key encryption
o Construction of anonymous authentication
protocols.
o PKI features.
o Hierarchical cross verification for organizations.
o Analysis on inter-domain scenario.

6. Continued…..
 Construction of an anonymous authentication &
authorization in cloud environment.
 This above mentioned architecture and the possible
solutions mentioned earlier , make a big impact in
the future.
 The industries have implemented techniques such
as OPEN ID, SHIBBOLETH & OAUTH.
 These methods or techniques have a great impact
in the area of cloud security or privacy in the
future or next 5 years.

7. Interest Areas
 As cloud security is the big concern these days ,
privacy preservation & confidentiality etc , are the
areas I wish to work in.
 implementation of the variously mentioned
techniques and architecture , benchmark & formal
security analysis of these protocols.
 If given an internship , I would like to work with
developing powerful & efficient cryptographic
methods or techniques to ensure data integrity ,
confidentiality & anonymity among the
organizations.
