Provided are a storage device and an operating method thereof. The storage device includes: a memory storing parameter data that is used as an input in a neural network; and a storage controller configured to receive a request signal from a host, encode log data for contexts of a plurality of components in the neural network, based on the parameter data, and transmit the encoded log data to the host.

Storage device for reducing or preventing successful attacks by malicious users and operating method thereof

An electronic device includes a memory storing data from an external source, an application processing unit (APU) transmitting a secret key and public key generation command, an isolated execution environment (IEE) generating a secret key in response to the secret key generation command, generating a public key based on the secret key in response to the public key generation command, and storing the secret key, and a non-volatile memory performing write and read operations depending on a request of the APU. When the data are stored in the memory, the APU transmits a public key request to the IEE and in response the IEE transfers the public key to the APU through a mailbox protocol. The APU generates a ciphertext by performing homomorphic encryption on the data based on an encryption key in the public key, and classifies and stores the public key and the ciphertext in the non-volatile memory.
