The techniques include receiving, by a session manager service, a request to connect a user device to a secure connection to a secure shell instance. The session manager service may authorize the user device to access the secure shell instance and may configure the secure shell instance, being described by a shell identifier of the secure shell instance. The techniques also include generating, by the session manager service, a nonce token and providing the shell identifier, and a router address of the secure shell router to the user device. The techniques also include generating, by the session manager service, a signed nonce token using the nonce token; and providing the signed nonce token and the shell identifier to a user device. | 2022-02-17 |
20220052850 | TURN AUTHENTICATION USING SIP CHANNEL DISCOVERY - In one embodiment, an endpoint in a network sends a Session Initiation Protocol (SIP) registration request to a device. The device generates a first key using information included in the SIP registration request. The device also writes the first key to a storage location accessible by a Traversal Using Relays around Network address translators (TURN) server. The endpoint generates a second key based on the information included in the SIP registration request. The endpoint sends an allocate request to the TURN server that includes the second key. The TURN server authenticates the endpoint based in part by comparing the second key to the first key. The endpoint receives an allocate response from the TURN server, after the TURN server authenticates the endpoint. | 2022-02-17 |
20220052851 | Methods for Optical Image Encryption and Decryption Based on Biological Information - Image encryption and decryption methods based on biological information. The encryption method includes: obtaining the biological information; using the chaotic mapping method to preprocess the biological information to construct the first chaotic biological phase plate and the second chaotic biological phase plate; obtaining the original image to be encrypted and use the first chaotic biological phase plate and the second chaotic biological phase plate to determine the reconstructed optical encrypted image based on the discrete cosine transform method, and Fresnel transform method; and inputting reference light that interferes with the encrypted image of the reproduction light to determine the encrypted image. The invention can reduce the information amount of the key, improve the efficiency of storage and transmission, and improve security. | 2022-02-17 |
20220052852 | SECURE BIOMETRIC AUTHENTICATION USING ELECTRONIC IDENTITY - Embodiments of the invention are directed to a method. The method may comprise receiving a second biometric template of a user, and providing an authentication request message comprising an electronic identity and a derivative of the second biometric template of the user to a resource provider computer to conduct an interaction. The authentication request may be forwarded to a processing server computer by the resource provider computer, and the user device may receive an authentication response message comprising an authentication result from the processing server computer. The authentication result may be determined by the processing server computer based on a comparison of the derivative of the second biometric template to a derivative of a first biometric template accessible to the processing server computer. The authentication result may also be based on the validity of the electronic identity. | 2022-02-17 |
