Abstract: A method for confidential computing is provided, which is performed by a security core including one or more processor, and includes storing first encrypted data associated with a first tenant in a first memory, in which the first encrypted data is obtained by performing encryption of the first plaintext data using a first encryption key associated with the first tenant, in response to receiving a request to access the first plaintext data, decrypting the first encrypted data using the first encryption key so as to generate the first plaintext data, and providing the first plaintext data to a main core that processes data stored in the first memory.

Abstract: A method for runtime integrity check, performed by a security core including one or more processors includes storing a first output value, which is generated by using a one-way encryption algorithm based on first data and a first encryption key managed by an encryption key manager accessible by the security core, in a main memory that is a volatile memory in association with the first data, generating a second output value for the first data based on the first data and the first encryption key by using the one-way encryption algorithm, and checking for possible tampering of the first data stored in the main memory by comparing the first output value with the generated second output value.
