The disclosure discloses a computing task allocation method, an updating method for computing task allocation, a terminal and a network device. When a computing task of a terminal is generated, computing task allocation is performed using at least one of a centralized mode, a distributed mode, or a hybrid mode; the computing task allocation includes communication resource allocation, computing resource allocation, and a task offloading decision; the above computing task allocation method subjected to dynamically updating according to a terminal state, a network state or a task state. Therefore, the compromise problem between overall system performance optimization and device fairness in a cloud-edge collaborative IoT system is solved.

Methods, terminals and network devices for computing task allocation and updating

The present disclosure provides methods and apparatuses for improving user security of satellite-ground integrated network systems. On the basis of the satellite-ground integrated network pipeline only authenticates a terminal in a satellite-ground integrated network, a two-stage authentication based on CA digital certificates and user characteristic information is put forward for users and services using the terminal. The two-stage authentication includes: firstly, when a first spatio-temporal information ciphertext digest obtained from spatio-temporal information ciphertext in a service request by using a digest algorithm is consistent with a second spatio-temporal information ciphertext digest obtained by decrypting a digital signature in the service request using a user public key, the user is legal; furthermore, when spatio-temporal information characteristics obtained by decrypting the spatio-temporal information ciphertext using a private key of the satellite-ground integrated core network are consistent with spatio-temporal characteristics in the digital certificate, the verification succeeds.
