Abstract
A method for generating a key includes: obtaining key parameters indicated by a network side, the key parameters at least comprising a next hop chaining counter (NCC) and frequency point information for generating a key, the frequency information being a frequency of one Synchronization Signal Block (SSB) of a target cell; and generating an AS key based on the key parameters.
Claims20
A method for generating a key, applied to a piece of User Equipment (UE), the method comprising:
- obtaining key parameters indicated by a network side, wherein the key parameters comprise at least a Next Hop Chaining Counter (NCC), and frequency information for generating the key, the frequency information being a frequency of one Synchronization Signal Block (SSB) of a target cell;
- and
- generating an Access Stratum (AS) key based on the key parameters.
A method for generating a key, applied to a network device, the method comprising:
- indicating key parameters to a piece of User Equipment (UE), wherein the key parameters comprise at least a Next Hop Chaining Counter (NCC) and frequency information for generating the key, the frequency information being a frequency of one Synchronization Signal Block (SSB) of a target cell, and the key parameters being used by the UE for generating an Access Stratum (AS) key.
A piece of User Equipment (UE), comprising:
- a memory storing processor-executable instructions;
- and
- a processor configured to execute the stored processor-executable instructions to perform operations of:
- obtaining key parameters indicated by a network side, wherein the key parameters comprise at least a Next Hop Chaining Counter (NCC) and frequency information for generating a key, the frequency information being a frequency of one Synchronization Signal Block (SSB) of a target cell;
- and
- generating an Access Stratum (AS) key based on the key parameters.
A network device, comprising:
- a memory storing processor-executable instructions;
- and
- a processor configured to execute the stored processor-executable instructions to perform an operation of:
- indicating key parameters to User Equipment (UE), wherein the key parameters comprise at least a Next Hop Chaining Counter (NCC) and frequency information for generating the key, the frequency information being a frequency of one Synchronization Signal Block (SSB) of a target cell, and the key parameters being used by the UE for generating an Access Stratum (AS) key.
