An Assessment on Identity based Encryption Mechanisms in Cloud Computing
Cloud computing is an emerging trend at present, in which cloud providers can remotely store the data in the cloud in a server and provide the services to the cloud user's on-demand via the internet. Data sharing is the major concern in cloud storage. Data security and privacy are the critical issues for remote data storage. In order to share the data securely, it is necessary to adopt an efficient encryption system. Identity based encryption is a public key based encryption in which the public key of the user contains some distinct information about the user's identity (e.g. user's email address).
