Abstract: A user authentication method performed in an unmanned delivery system including a server, a buyer customer device, a deliveryman customer device, and an autonomous delivery vehicle includes: generating, by the server, a session key based on order information received from the buyer customer device, and transmitting the generated session key to the deliveryman customer device and the buyer customer device; generating, by the deliveryman customer device, a One-Time Password (OTP) based on the session key; applying, by the deliveryman customer device as a first application step, a hash function to the OTP a first predetermined number of times; additionally applying, by the deliveryman customer device as a second application step, the hash function to the OTP generated in the first application step a second predetermined number of times; and generating, by the deliveryman customer device, a first Quick Response (QR) code based on the OTP generated in the second application step.

Abstract: Provided is a jamming defense system. In the jamming defense system for wireless local area network communication between an access point (AP) and a user node, the AP that transmits and receives a message to and from the user node generates an AP secret key value by measuring a signal reception strength for the message, and the user node that transmits and receives a message to and from the AP generates a user node secret key value by measuring a signal reception strength for the message.

Abstract: A smart key authentication method for a vehicle remote key system that includes a smart key performing bi-directional communication with a vehicle to control the vehicle and a vehicle authentication module provided at the vehicle to authenticate the smart key is provided. The smart key authentication method includes generating, by the vehicle authentication module, a random number and sharing the random number with the smart key and performing a first authentication process based on the random number, and performing, by the vehicle authentication module, a second authentication process by comparing at least one location information value among an access point (AP) list, a satellite-based positioning sensor value, or a geomagnetic sensor value, which are respectively measured at the vehicle and at the smart key and determining whether or not to permit an authentication to the smart key.
