Abstract
To speed up an operation by a full adder that achieves full homomorphic encryption, a ciphertext processed by an encryption processing device has two values as a plaintext and is a ciphertext of fully homomorphic encryption that allows various operations to be performed by performing a logical operation without performing decryption. The encryption processing device includes an operation unit that performs a logical operation for a ciphertext received by a receiving unit and an output unit that outputs a result of the operation by the operation unit. The operation unit reduces the number of logical operations (homomorphic operations) by temporarily using a specific ciphertext that can have multiple values as a plaintext.
