Abstract
This work aims at implementing new approaches for Virtual Identity (VId) in cloud environments. Our objective is to create an identity that could help in preventing the reverse of access chain in the cloud through hiding the main user identity. This means that, instead of executing a service for a known identity in cloud environment (unknown place), we hope to execute a service with an unknown identity (VId) in an unknown environment. For achieving the high degree of security and efficiency, we implement a new anonymous access for cloud environments using VId. This identity is implemented and verified using Multi-precision Integer and Rational Arithmetic C/C++ (MIRACL library) either Identity Based Encryption (IBE) or Pseudonym Based Encryption (PBE) mechanisms. By this, a comparison between our protocols and the previous identity mechanisms used in cloud is conducted to highlight the main issues, and pros & cons for each approach.
