j'aimerais bien que vous m'aider dans la traduction de "challenge response"
en fait j'hésite entre réponse à une demande d'accès" "réponse à un défi" ....



contexte "Many electronic devices including mobile devices have at least one challenge based locking mechanism for improving the security of the device and any data stored on the device. A challenge, such as a password prompt, can be used to authenticate a user who is attempting to access or use a device or system. One challenge based locking mechanism is the locking feature on a mobile device. A challenge based locking mechanism can allow a device to be put into a locked state, in which user access to some or all of the functionality of the device is temporarily disabled. The device may be switched into an unlocked state upon the successful completion of a challenge, meaning that user access to some or all of the functionality of the device is enabled.

"If the challenge response is accepted by the device, the device enters an unlocked state. In the present embodiment, the challenge response is in the form of a password. If a temporary lock time value has been appended to the password, the device will enter an unlocked state as usual. However, the automatic lock timer will be started with the inputted automatic lock time value rather than the default automatic lock time value. The device can use this temporary automatic lock time value until the next time the device enters a locked state. The next time the device is unlocked, the automatic lock time value is typically set to the default value unless another temporary automatic lock time is inputted to the device. In this embodiment, the temporary automatic lock time value has a one-time use lifespan."
