Dynamic Multi-path and Multi-protocol Encrypted Communication Mechanism

Traditional network encryption mechanisms have many drawbacks, such as low encryption efficiency. In order to solve these problems, the paper proposes a new dynamic multi-path and multi-protocol encryption communication mechanism, which improves the universality of encryption algorithms and encryption efficiency while ensuring the security and privacy of user information. At the same time, the trade-off between information security and resource consumption is considered. The whole system is implemented by SDN, and the data plane adopts P4 technology. It is verified that the proposed method has a shorter encryption and decryption time than AES and RSA, and reduces the resource overhead of the system, and has stronger practicability.
