Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

Abstract: An identity authentication method is disclosed in embodiments of the present application. When a requester and an authentication access controller perform identity authentication using an authentication mechanism of a pre-shared key, the identity information of entities is transmitted in the form of ciphertext, thereby preventing the identity information of the entities from being exposed during the transmission, so that attackers cannot obtain private or sensitive information. The mutual or unilateral identity authentication between the authentication access controller and the requester is achieved while ensuring the confidentiality of the entity identity and related information, thereby laying a foundation for ensuring that the user accessing the network is legitimate and/or the network accessed by the user is legitimate.

Abstract: Disclosed is an identity authentication method. When a request device and an authentication access controller perform identity verification on the basis of an authentication mechanism of a pre-shared key, identity information of a verified party is transmitted in the form of a ciphertext, thereby preventing the identity information of the verified party from being directly exposed during transmission, and ensuring that an attacker cannot obtain private and sensitive information. Two-way or one-way identity authentication between the authentication access controller and the request device is realized, while the confidentiality of entity identity related information is ensured, thereby laying the foundation for ensuring that a user accessing a network is legitimate and/or the network accessed by the user is legitimate.
