摘要： An authentication method for link protection between an OLT and an ONU newly connected thereto in an EPON, which is implemented in a data link layer to which cryptography is applied. First, an authentication key is distributed to both the OLT and an ONU. The OLT (or ONU) generates first and second random values, generates an authentication request frame containing the random values, and transmits it to the ONU (or OLT). The ONU generates a first hash value according to a hash function using the random values contained in the request frame, and transmits an authentication response frame containing the first hash value to the OLT. The OLT compares the first hash value with a second hash value calculated by it according to the has function using the two random values and an authentication key distributed to it, and transmits an authentication result frame to the ONU.

摘要： A system for providing image information while interworking with a plurality of photographing apparatuses converts each of at least one image transmitted from the plurality of photographing apparatuses into a frame, and inserts the coordinates of the intersection into the converted frame. Next, the system determines whether a vehicle enters the intersection based on the frame into which the coordinates of the intersection are inserted, the current travelling direction of the vehicle, and the current position coordinates of the vehicle. The system extracts image information of the road intersecting at the frame corresponding to each of at least one image, when the vehicle enters the vehicle, and provides the extracted image information to the user through a terminal in the vehicle.
