Ciphertext Policy Attribute Based Encryption for Secured Data Retrieval in Military Networks Using Role Based Access Control Policy
Abstract— Mobile nodes are dynamic nodes that are moveable from one place to another. Mobile nodes in military environments are known as Military Networks. These networks are likely to suffer from intermittent network connectivity and frequent partitions. Military networks has to access the confidential information or command between the soldiers and commanders. Security has to be provided for accessing confidential information by implementing access control policies. An access control scheme was proposed which is based on the Ciphertext Policy Attributed-Based Encryption (CP-ABE) approach. A flexible fine-grained access control was approached such that the encrypted contents can only be accessed by authorized users. All user’s private key is associated with a set of attributes (describing the user) and an encrypted ciphertext will specify an access policy over attributes. A user will be able to decrypt if and only if his attributes satisfy the ciphertext’s policy. Ciphertext Policy Attribute-Based Encryption (CP-ABE) are used for high level security regard to attribute revocation, key escrow, and coordination of attributes from different authorities. CP-ABE along with role based access control policy will ensure secure data retrieval in military networks. CP-ABE Performs the access control and secures data retrieval issues by its scalable cryptographic solution and data are transferred with the use of attribute key. Military Networks introduces several security challenges such as attribute revocation, key escrow, and coordination of attributes due to the CP-ABE. The issues can be overcome by CP-ABE mechanism for securely and efficiently manage the confidential data.
