Abstract—In mobile networks, information security is of importance to most if not all applications. In this paper, we propose rank and geographic location based security mechanism in a mobile network scenario. Both sender and receiver are highly mobile and their public keys are known by all nodes. We extend the scheme of encryption/decryption on the basis of geo-encryption algorithm in [1]-[3] by adding information rank and person rank into consideration. The receiving nodes must be physically present in a designed decryption region and with correct security clearance rank to decrypt ciphertext within allowed time period. We also present algorithms to predict and update the decryption region in high mobility mode. The proposed method evaluated by simulations is efficient and secure.
