(57) Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage me
" dia, for performing cryptographic operations subject to identity verification. One of the methods includes receiving, by a cryptography 
chip, a request to perform a requested cryptographic operation from a client including client identity information, wherein the cryptog
raphy chip includes a processing resource that performs cryptographic operations and a storage resource that stores key information used 
C in the cryptographic operations, and identity information associated with clients that are permitted to request cryptographic operations; 
determining, by the cryptography chip, that the client identity information is associated with one of the clients that are permitted to 
C request cryptographic operations; and performing, by the cryptography chip, the requested cryptographic operation based on the key 
information stored in the storage resource.
