Abstract: A storage device includes a non-volatile memory including a plurality of namespaces including a plurality of logical blocks; and a storage controller configured to, for each of the plurality of namespaces, check a capacity that is a number of allocable logical blocks, among the plurality of logical blocks, and a size that is a sum of a number of currently allocated logical blocks, among the plurality of logical blocks, and the number of allocable logical blocks, detect a first namespace, among the plurality of namespaces, by using the capacity and the size, and provide at least a portion of the allocable logical blocks of a second namespace, among the plurality of namespaces, to the first namespace.

Abstract: An electronic device includes a host device and a plurality of storage devices. The host device includes a processor and a baseboard management controller (BMC). Each of the plurality of storage devices includes a storage controller and a micro controller unit (MCU). The processor and the storage controller support in-band communication, and the BMC and the MCU support out-of-band communication. The BMC receives monitoring data from the MCU of each of the plurality of storage devices based on the out-of-band communication. The processor allocates a first workload among one or more workloads to a first storage device among the plurality of storage devices, based on a monitoring data set including the monitoring data. The first storage device executes the first workload based on the in-band communication.

Abstract: An authentication method including, at an apparatus—generating a master secret key and a master public key, generating a secret key and a public key using enrollment target personal information, the master secret key and the master public key, and generating first information using the enrollment target personal information. Communicating the secret key and the first information from the apparatus to the authentication server, storing the secret key and the first information in a secure area of the authentication server, generating at the apparatus, a ciphertext encrypted using authentication target personal information and the public key, second information using the authentication target personal information and communicating the ciphertext and the second information from the apparatus to the authentication server. At the authentication server, performing an authentication of the authentication target personal information using the secret key, the first information, the ciphertext and the second information, wherein the performing of the authentication of the authentication target personal information includes calculating a similarity between the enrollment target personal information and the authentication target personal information by computing an Euclidean distance of the enrollment target personal information and the authentication target personal information, and the performing of the authentication of the authentication target personal information is performed in relation to the similarity.

Abstract: An operating method for a storage device including a storage controller and a non-volatile memory may include; receiving a command including data and a field related to the data from a host, determining an operation mode based on the command, selectively encrypting the data based on the operation mode to generate selectively encrypted data, and storing the selectively encrypted data in the non-volatile memory, wherein the selectively encrypting of the data includes encrypting the data based on a first encryption algorithm when the operation mode is a first operation mode, and encrypting the data based on a second encryption algorithm different from the first encryption algorithm when the operation mode is a second operation mode.
