  • Publication number: 20250038998
    Abstract: The present invention relates to a cyber security authentication method. The method includes the following steps: in a user device: randomly generating an ephemeral decryption key, transmitting the ephemeral decryption key to a security server, and retrieving a key index from the security server; encrypting an identity information based on a part of the ephemeral decryption key to generate an electronic digital signature and an authentication token; and combining the key index, the electronic digital signature, and the authentication token to form an ephemeral certificate and transmitting the ephemeral certificate to a non-Internet electronic device; and in the non-Internet electronic device: parsing the ephemeral certificate to obtain the key index; and forwarding the key index to the security server via a transport connection including the user device to retrieve the ephemeral decryption key from the security server based on the key index.

  • Publication number: 20020079700
    Abstract: A fast rotation joint is disclosed. The fast rotation joint is engaged between a machine body and a joint of the transferring flexible tube. The fast rotation joint includes mainly a first main body, a second main body, and a third main body. A drain-preventing pad is illustrated between the first main body and the second main body. The drain-preventing pad is used to prevent air from drainage so that the pressure will be insufficient. A plurality of rollers are mounted between the second main body and the - :third main body for preventing the deformation from the engagement of the machine body with the transferring flexible tube so as to increase the lifetime of the transferring flexible tube and the joint.
