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.
