An electronic device according to various embodiments of the disclosure may include a housing including a first plate forming an outer face. The first plate may include a glass plate including a first surface outwardly facing the housing and a second surface inwardly facing the housing, a coating layer including an anti-reflection coating and/or an anti-finger coating above the first surface while forming the outer face, a first layer formed between the first surface of the first glass plate and the coating layer, having a first thickness, and including a first inorganic material, a second layer formed between the first layer and the coating layer, having a second thickness, and including a second inorganic material different from the first inorganic material, a third layer formed between the second layer and the coating layer, having a third thickness thicker than each of the first thickness and the second thickness, and including a third inorganic material, and an opaque layer formed on the second surface. Various other embodiments may also be possible.

Electronic device comprising high hardness color structure layer

An apparatus configured to transmit and receive a radio frequency (RF) signal is provided. The apparatus includes a digital-to-analog converter (DAC) configured to convert a digital signal into an analog signal, a power amplifier configured to amplify the analog signal, and an antenna configured to output, as the RF signal, the amplified analog signal to the outside. The DAC includes a current cell matrix including a plurality of current cells configured to generate the analog signal, a plurality of normal paths configured to control the plurality of current cells to be turned on or off, based on the digital signal, and a plurality of alternative paths configured to selectively consume power, based on a pattern of the digital signal.

Digital-to-analog converter and apparatus including the same

Disclosed is a vehicle information inquiry method including a logging step of acquiring an event ID for sharing anonymized vehicle information and vehicle travel information corresponding to the event ID from an external device, by a central server, a query step of receiving an inquiry about the event ID and the vehicle travel information corresponding to the event ID from an inquiry server, by the central server, and a responding step of transmitting the vehicle travel information corresponding to the event ID received from the inquiry server to the inquiry server, by the central server.

Vehicle information inquiry method

Disclosed is a vehicular update system including a communication device configured to communicate between a server and a controller included in a vehicle, a memory, and a controller configured to, (i) when a public key set including a root public key for verifying a root signature is stored in the memory, acquire the root signature from the server and verify root metadata based on the acquired root signature and the root public key of the public key set pre-stored in the memory, and configured to, (ii) when the public key set is not stored in the memory, acquire, from the server, root metadata including a public key set and a root signature obtained by performing a digital signature on a hash value of the public key set using a root private key, verify the root metadata based on the root public key of the acquired root metadata and the root signature, and store the public key set.

Vehicular update system and control method thereof

A vehicular firewall providing device includes a processor configured to match a data packet received from an external device and a plurality of rules at a set order, and to perform rule reordering defined to change the order based on a matching result. The processor is further configured to perform the rule reordering after the state, in which the vehicle autonomously travels, is terminated, upon detecting a hacking attack sign in a state in which a vehicle autonomously travels.
