Abstract |
A virtual host computer system that enables enterprises to buy, lease, sell, or distribute software and other digital resources over the internet as an on-demand service is cloud computing. Though the new paradigm of cloud computing provides great advantages, there are meanwhile also concerns about security and privacy for web based cloud services. A multi-factor authentication and access control system for web-based cloud computing services is developed. In the proposed authenticated access control system, an attribute-based access control mechanism is implemented with the necessity of both user secret key and a trusted security key response. The login of the user is secured by one time key password system (OTP) and each login is secured with session keys i.e. The user is allowed to work only for a permitted time period. A user cannot access the system if she /he does not hold all the three factors: the OTP, secret key, secret key response, the mechanism enhances the security of the system, especially in those cases where many users share the same computer for web-based cloud services. In addition, attribute-based control in the system also enables the cloud server to restrict the access to those users with the same set of attributes while preserving user privacy, the user .The cloud server only knows that the user fulfills the required predicate, but has no idea on the exact identity of the user the cloud holds the user with attributes and the polices. The cloud servers cant access the files of the user i.e. the files stored are in an encrypted format the encryption key is given by only the user. |
