Abstract
Cyber Security, over the last few years, has been a topic of great research given the number of cyber crimes have been increasing. To provide cyber security , constant efforts are being made to secure the communications and to protect user data using various cryptography techniques. With the increasing number of cryptography, the number of keys used to secure communications also sees a high. It is always difficult to manage these keys and their identity in a multi process communication environment. This paper brings into light an approach for the enhancement of data security and cryptographic key management using a policy based key management system. An on the device approach is proposed which uses the file system to create a secure storage with enhanced security for the storage of the data . The access to this storage is governed by policies to allow an application based access to the storage. This model will provide a highly scalable secure storage and management of keys.
Highlights
All the devices use many secrets and protected information, as well use cryptographic keys for secure communication
The secrets need to be stored in a consistent way across the system; and the storage mechanism must ensure that secrets on one device are locked for that particular device and are not transferrable unless authorized This is key for virtual platforms that run as virtual machines that can be cloned
All of the work reviewed does bring new insights into their application domains, none of the existing studies considers the problem of ensuring both storage security as well as policy and role based access mechanism to provide a comprehensive solution for the cryptographic key management
Summary
All the devices use many secrets and protected information, as well use cryptographic keys for secure communication. These information are all stored by different subsystems in different ways that results in an inconsistent security posture for the overall system. The vault is used to govern the policies for all the applications running on the device and the virtual TPM is the storage which stores the data by maintaining high security by using the security features of the Trusted Platform Module which is present on all devices.
