An identity-based security infrastructure for Cloud environments

This paper presents a novel security infrastructure for deploying and using service-oriented Cloud applications securely without having to face the complexity associated with certificate management. The proposal is based on an identity-based cryptographic approach that offers an independent setup of security domains and does not require a trust hierarchy compared to other identity-based cryptographic systems. The service URLs can be used as public keys, such that creating a secure connection to a service is very simple. A comparison between traditional approaches and identity-based cryptography with respect to data transfer requirements is presented.
