A data input method and apparatus, and user equipment are provided. The method includes: when it is determined that an operation of a user on the user equipment UE is not performed in a preset display area, deliver an event corresponding to the operation to a first operating environment for processing, where the preset display area runs in a second operating environment of the UE, and the second operating environment has a higher security level than the first operating environment. This can better improve security of an event generated when the user operates a program that runs in a Normal World of the user equipment, and can directly operate an event that runs in the Normal World.

Data input method and apparatus and user equipment

An apparatus including a processor and a memory, where the processor and the memory are configured to provide a secure execution environment and the memory stores a hardware unique key and a class key. The processor is configured to recover, in the secure execution environment, a certificate signing key based on the class key, where the certificate signing key is associated with a certificate authority. The processor is further configured to derive a device key pair based on the hardware unique key, where the device key pair includes a device public key and a device private key, and generate a device certificate based on the device public key and the certificate signing key. The generated device certificate is configured to be validated based on a public key associated with the certificate authority.
