Abstract

The invention provides a key management method and device, and relates to the technical field of encryption. The method comprises the following steps: after confirming that a user logs in a digital identity through a first identity authentication mode, obtaining a first authentication decryption key corresponding to the first identity authentication mode; an initial encryption first role decryption key is obtained from the server side, the initial encryption first role decryption key is decrypted by using the first authentication decryption key to obtain a first role decryption key, and the first role decryption key corresponds to a first role in the at least one role of the digital identity; based on the first role decryption key, the encrypted target key stored in the digital identity is decrypted to obtain the target key, and the target key is used for managing assets corresponding to the first role. According to the technical scheme provided by the invention, the user can log in the digital identity through the existing identity information, asset management can be realized without memorizing a tedious and complex key, and great convenience is provided for the user.
