Abstract

In this paper, we present an efficient, low-bandwidth cost and security-enhancing data encryption d-key protocol via dynamic re-keying during end-to-end communication. Unlike others, the secret d-key is generated using the previous data as the seed and as next packet encryption; therefore, only valid sender and receiver are able to decrypt the cipher text using the unique d-key in their possession, which prevents sensitive data from being access by unauthorized recipients. In addition, test results indicate d-key protocol can perform as efficiently as a non-security routing protocol while providing stronger data privacy with low computational overhead in data encryption and decryption.
