Abstract: A device for supporting a homomorphic encryption operation includes a ciphertext conversion circuit configured to convert first ciphertexts corresponding to a first operation size to second ciphertexts corresponding to a second operation size, different from the first operation size, to convert the operated ciphertext having the second operation size to a third ciphertexts corresponding to the first operation size, and to perform a homomorphic encryption operation on the second ciphertexts.

Abstract: A redundant array of inexpensive disks (RAID) controller of a RAID storage system that includes one or more storage devices includes an error correction code (ECC) result manager configured to manage information of ECC result indicators when a data chunk that includes one or more ECC data units having an uncorrectable ECC error is read from among a plurality of data chunks dispersively stored in the one or more storage devices, each of the plurality of data chunks including a plurality of ECC data units, the ECC result indicators respectively indicating whether the plurality of ECC data units included in the plurality of data chunks has an uncorrectable ECC error; and an uncorrectable error counter configured to calculate a number of ECC result indicators indicating an uncorrectable ECC error among ECC result indicators corresponding to ECC data units having a same order in each of the plurality pluralit.y of data chunks.

Abstract: Encoding and decoding apparatuses and methods for implementing multi-mode coding are provided. The apparatus includes a transmitter and a receiver connected to a data bus. When data bursts are converted by the transmitter into codewords each including a plurality of symbols and/or a codeword received by the receiver is recovered as data bursts, maximum transition avoidance (MTA) codeword mappings in which no maximum transition (MT) event occurs between the plurality of symbols and minimum DC current (MDC) codeword mappings related to minimum power consumption of the plurality of symbols are used.

Abstract: A homomorphic encryption system includes a homomorphic encryption device encrypting original data into a first ciphertext using a homomorphic encryption algorithm, and a homomorphic encryption operation device receiving the first ciphertext from the homomorphic encryption device and performing an approximate arithmetic operation of a transcendental function with respect to the first ciphertext and a second ciphertext by performing a homomorphic multiplication operation in a binary tree structure.

Abstract: A method of transmitting data in a storage device includes encrypting original data based on a homomorphic encryption algorithm to generate encrypted data, generating a parameter for regeneration of a ciphertext higher than an operation level of the encrypted data by using the encrypted data and a key value, and transmitting the encrypted data and the parameter to an external host device.
