Traceability Acquisition Method for Network Security using Multiple Encryption and Decryption of the Tag in Packet

摘要

Multi-factor authentication is used to improves the existing vulnerability of traditional password authentication, such as biometric and one-time password token. However, these methods foist a burden on the user. We propose the traceability acquisition method in a network for the user authentication, which runs only on the routers; thereby it achieves secure and authenticated communication between a user and a server application without any burden on the users and applications. In this method, "tracer tags" is introduced for attaining packet traceability of a packet and the tags are encrypted with unique router's key. Recipient makes sure that packet has delivered through the expected routing path by decrypting a tracer tag. The Proposed method achieved secure and authorized communication using packet traceability without any additional effort to users The proposed method is evaluated in a virtual environment. By using the proposed method, routing throughput decreased only by 3% compared with normal routing.
