Enhanced Security Model for Cloud Using Ones compliment Re-coding for Fast Scalar multiplication in ECC

Defining cloud computing becomes a difficult task with many definitions, yet no consensus on single or unique on ones. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. With a promising technology like this, it certainly abdicates users' privacy, putting new security threats towards the certitude of data in cloud.
