Security plays a vital role in Cloud Computing Services. Public Key Encryption is the mostly used method to provide security that needs sharing the public keys and digital certificates. Securing the data and resources in the Cloud is a difficult task. If the security method adopted in cloud environment is not understandable by the user, then the user may leave the service or application. So an easy-to-use security method is required for cloud applications. In this paper we propose the light weight Secure Framework for Applications of Cloud Environment using Identity Based Cryptography that overcomes the problems of existing security approaches. A mail application is developed to demonstrate the simplicity of proposed approach using Identity-Based Cryptography. Our approach allows several domains to execute independently and clearly depicts the complexity involved in Certificate Based Infrastructures and encourages the use of novel Identity-Based Infrastructure, which is easy to perform and less complex than the traditional public key algorithms.
