Abstract
In a method for encryption of sensitive data, an encrypted user private key is received in a Trusted Execution Environment (TEE) in a worker node in a container management system, the encrypted user private key being an encrypted version of a user private key for decrypting a message from a user in the container management system. The user private key is obtained in the TEE, and the encrypted user private key being decrypted into the user private key with a provider private key that is received from an encryption manager for managing the container management system. With these embodiments, the user private key may be transmitted to the worker node safely, such that the worker node may use the user private key to decrypt messages from the user. Therefore, the security level of the container management system may be increased.
