摘要
Provided is a process including: encrypting each of a plurality of data encryption keys with a first public cryptographic key to form encrypted data encryption keys; obtaining a second public cryptographic key; generating a transformation key based on the first public-private cryptographic key pair and the second public cryptographic key; and transforming the encrypted data encryption keys with proxy re-encryption based on the transformation key; and obtaining the second private cryptographic key and the transformed encrypted data encryption keys.
