An Asymmetric Key based Disk Encryption Scheme

This paper prompts to understand an asymmetric key based improved disk encryption scheme designed in a tree structure, and analyses the security of encrypted disk data. Conventional disk encryption software use encryption cryptography based on symmetric key, and unable to protect the secret key due to design and implementation weaknesses. Hence, a disk encryption scheme is proposed here which uses asymmetric key cryptography to ensure stronger data security by utilizing the advantage of having two keys over one keyed symmetric key cryptography. The conceptual model includes entangling asymmetric key cryptography with tree structure to provide multiple encrypted layers embedded within the nodes from leaf to root.
