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.

Electronic device using homomorphic encryption and encrypted data processing method thereof

An artificial intelligence calculation semiconductor device is provided. The artificial intelligence calculation semiconductor device comprising: a control unit; and a MAC (Multiply and Accumulator) calculator which executes a homomorphic encryption calculation through the control unit, wherein the MAC calculator includes an NTT (Numeric Theoretic Transform)/INTT (Inverse NTT) circuit which generates cipher texts by performing a homomorphic multiplication calculation through transformation or inverse transformation of data, a cipher text multiplier which executes a multiplication calculation between the cipher texts, a cipher text adder/subtractor which executes addition and/or subtraction calculations between the cipher texts, and a rotator which performs a cyclic shift of a slot of the cipher texts.

Artificial intelligence calculation semiconductor device and storage device comprising the same

Provided is a lighting apparatus including a memory configured to store wireless network information of the lighting apparatus, a detection circuit configured to detect an alternating current signal supplied to the lighting apparatus, and a processor configured to initialize wireless network information of the lighting apparatus, based on the detected alternating current signal.

Lighting apparatus that determines whether network information to connect to a network is effective and method of controlling the same

A lighting apparatus connected to a network includes a light source for emitting light. A controller controls operation of the light source in response to an external control signal. A non-contact sensor detects a non-contact signal and generates a reset signal in response to detecting the non-contact signal. A communication interface communicatively connects the lighting apparatus to a wireless network to receive the external control signal from a remote apparatus via the wireless network and disconnects the lighting apparatus from the wireless network in response to receiving the reset signal from the non-contact sensor.

Lighting apparatus, lighting control system, and method of controlling the lighting apparatus

A power saving mode is provided. A method for entering a power saving mode of a terminal includes a first operation for starting a first timer after transmitting an idle mode request message; a second operation for, when an idle mode approval message is not received until the first timer expires, checking whether a number of retransmissions of the idle mode request message exceeds a number of allowed retransmissions of the idle mode request message; a third operation for, when the number of the retransmissions of the idle mode request message exceeds the number of the allowed retransmissions of the idle mode request message, increasing a number of idle mode entry failures; and a fourth operation for, when the increased number of the idle mode entry failures is greater than N times, entering a power saving mode which powers off a modem.

Apparatus and method for entering idle mode in a broadband wireless access (BWA) system

An apparatus and method for supporting an Assisted Global Positioning System (AGPS) during emergency service in a communication system are provided. The system includes a client, an integration location server, and a dual mode Mobile Station (MS). The client requests MS location information for emergency service. The integration location server receives MS access information and sends a location information request. The dual mode MS receives the location request, activates a second communication modem, and performs an AGPS operation with the integration location server.
