    Abstract: In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device comprises a first subscriber identity module (SIM) and a second SIM, a first communication circuitry configured to perform wireless communication over a cellular network, a second communication circuitry configured to perform wireless communication over a Wi-Fi network, and at least one processor operatively connected with the first SIM, the second SIM, the first communication circuitry, and the second communication circuitry. The at least one processor is configured to perform a packet-based call associated with the first SIM using the first communication circuitry, and transmit a first re-registration message for internet protocol multimedia subsystem (IMS) re-registration for the second SIM to a network associated with the second SIM using the second communication circuitry, during the packet-based call associated with the first SIM.

    Abstract: Disclosed is a homomorphic encryption operation apparatus and method. The homomorphic encryption operation method is performed by a computing device that includes processing hardware and storage hardware, and the method includes: receiving, and storing in the storage hardware, a ciphertext including modules; receiving, and storing in the storage hardware, an operation key including a relinearization key corresponding to the ciphertext; and performing, by the processing hardware, a homomorphic encryption operation on the ciphertext, wherein a modulus of the ciphertext is determined by the processing hardware based on a dimension of the modules and a number of the modules.
