Abstract: A processor device includes a scheduler and a performance counter. The scheduler schedules commands of a first command set and commands of a second command set for a functional unit. A performance counter counts numbers of times where events of interest respectively occur while the functional unit processes first operations directed by the first command set and second operations directed by the second command set. The commands of the first command set are repeatedly scheduled such that the numbers of times for all the events of interest are counted with regard to the first operations. The commands of the second command set are scheduled after the numbers of times for all the events of interest are counted with regard to the first operations.

Abstract: An encryption key generating method and apparatus based on homomorphic encryption, and a ciphertext operation method and apparatus using the generated encrypt key are disclosed. The method of generating an encryption key for performing encryption based on homomorphic encryption includes receiving data, generating a first encryption key and a second encryption key used for encrypting the data based on a secret key, and transmitting the first and second encryption keys.

Abstract: Disclosed are apparatuses and methods with crypto processing. Computing devices may be interconnected to each other. Each computing device may be configured to perform polynomial operations based on homomorphic encryption. Memories may be configured to store instructions. Controllers may be configured to transfer instructions from the memories to the computing devices. One or more of the computing devices may each be configured to individually process, in parallel, at least a portion of the polynomial operations based on the homomorphic encryption according to an instruction transferred from a corresponding memory.
