AI Technical Summary
Technical Problem
Existing technologies struggle to effectively manage and update encrypted public keys in storage-constrained systems, resulting in high storage space requirements and high update costs.
Method used
By generating and characterizing the encrypted public and private keys as associated first and second encrypted components, a relation matrix is created and stored in the vehicle's electronic control unit. The public key is then regenerated from partial information of the encrypted private key using the relation matrix.
Benefits of technology
It significantly reduces the storage space required to store encrypted public and private keys, and lowers the cost of updating public keys from time to time.
