A key agreement system, method, and apparatus are provided. The method includes: generating, by a first device, a private-public key pair, sending a public key in the private-public key pair to a second device, and receiving a ciphertext and a commitment value; obtaining, by the first device, a first result, obtaining an original key based on a private key in the private-public key pair and the ciphertext, determining a second bit string based on some bits in the original key, calculating a second result based on the second bit string and the first result, and sending the second result to the second device; and receiving, by the first device, an opening value, performing authentication on the second device based on the opening value and the commitment value to obtain an authentication result, and generating a session key used to communicate with the second device.

Key agreement system, method, and apparatus

In a control system comprising control device adapted for, on the one hand, receiving signal indicating a first biometric datum (W), and, on the other hand, obtaining a second biometric datum captured (w'), at the level of the control device, the first and second biometric date are compared. Next, it is decided whether the first and second biometric data correspond on the basis of the comparison. Thereafter, at least a secret cryptographic key part (H(w)) is generated by applying cryptographic function to the first biometric datum.
