Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing cryptographic keys based on user identity information. One of the methods includes receiving a request to store identity information and a user key pair to a memory on a chip, the request being digitally signed with a digital signature, the identity information uniquely identifying the user, and the user key pair being assigned to the user; determining that the digital signature is authentic based on a public key pre-stored in the memory; encrypting the identity information and the user key pair; and storing the identity information and the user key pair to the memory.
