Abstract: An electronic device and a control method thereof are provided. The electronic device includes an Internet protocol (IP) address corresponding to a domain name of a web page when a user command inputting the domain name is received, identifies a number of hops included in a network path connecting a server corresponding to the obtained IP address and the electronic device to each other, and determines that a man-in-the-middle attack exists in a network when a communication connection with the server is established on the basis of a smaller number of hops than the identified number of hops.

Abstract: A method of a first electronic device which is connected to a fabric network supporting end-to-end encryption (E2EE) in a wireless communication system is provided. The method includes generating a fabric key based on a pre-stored first device key and a second member key received from a second electronic device, transmitting the fabric key to the second electronic device through a fabric server, which manages the fabric network, and a service server, which manages service data, encrypting service data based on the fabric key, and transmitting the encrypted data to the second electronic device through the service server, wherein the fabric key is shared with the fabric server, which is a member entity of the fabric network, and the second electronic device, wherein the encrypted data is decryptable at a member entity of the fabric network that shares the fabric key.

Abstract: A method of identifying a malicious access point (AP) by a terminal apparatus includes obtaining first performance information related to hardware of a first AP based on a first beacon signal received from the first AP, comparing the first performance information with previously stored second performance information of a second AP, and determining whether the first AP is a malicious AP, based on a result of the comparing.
