An apparatus includes: one or more memories configured to store an operation key comprising a re-linearization key and ciphertext comprising a plurality of modules; a controller configured to schedule a homomorphic encryption operation based on the ciphertext, based on at least one of the plurality of modules and a modulus of the ciphertext; and a plurality of operation devices configured to parallelly process respective parts of the homomorphic encryption operation according to a result of the scheduling.

Apparatus and method with homomorphic encryption

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.
