A method of translating an Internet protocol (IP) packet, the method including forming, by a first electronic device, a forwarding table by assigning a first IP address and a second IP address to a second electronic device, a tethering service being provided to the second electronic device through the first electronic device through an internal network, the first IP address and the second IP address having different formats and being associated in the forwarding table, and performing, by the first electronic device, an IP address translation on a first IP packet to be transmitted based on the forwarding table such that the first IP packet includes the first IP address or the second IP address, the first IP packet being included in a communication between the second electronic device and an external network through the internal network and the first electronic device.

Method of translating IP packet for tethering service, communication system and electronic device for performing the same

An electronic apparatus includes a first translation table that stores information of a first address and a second address; a second translation table that, in response to a condition being satisfied, stores the information of the first address and the second address based on the first translation table; at least one processor configured to translate the first address of a first packet to the second address based on the first translation table; and a forwarding manager that, in response to a second packet including the first address being received and the information of the first address and the second address being stored in the second translation table, translates the first address of the second packet to the second address based on the second translation table, prior to allocating the second packet to the at least one processor.

Electronic apparatus for providing fast packet forwarding with reference to additional network address translation table

An electronic device and method for providing vehicle information based on personal authentication and vehicle authentication are disclosed. According to various example embodiments, an electronic device includes a communication module comprising communication circuitry configured to communicate with a vehicle device and a first server and a processor electrically connected with the communication module, in which the processor is configured to receive an encrypted session key set including at least one session key from the first server, to transmit the encrypted session key set to the vehicle device, receive, from the vehicle device, second vehicle information in which first vehicle information of the vehicle device is encrypted using a first session key of the at least one session key and is signed using a secret key of the vehicle device, and to transmit, to the first server, third vehicle information in which the received second vehicle information is signed using a secret key of a user.
