摘要： A system and method for identifying a compromised controller using an intentional error are provided. The method, performed by an electronic device in a controller area network (CAN), for identifying a compromised electronic control unit (ECU) that transmits an attack message on a CAN bus in a periodic transmission cycle. The method includes, in response to detecting the attack message, transitioning a first ECU among a plurality of ECUs connected to the CAN bus to a bus-off state intentionally, and determining whether the first ECU is the compromised ECU based at least in part on a time, which is predicted from recovery parameters related to the first ECU, for when the first ECU resumes transmission of a CAN message and a time when the attack message is redetected on the CAN bus.

摘要： A public encryption method based on user ID includes: setting, by a key generation server, at least one public parameter and master key used for generating a private key; receiving, by the key generation server, an inherent ID of a user from a receiving terminal, generating a private key based on the public parameter, the master key and the ID, and transmitting the generated private key to the receiving terminal; receiving, by a transmitting terminal, the public parameter and the ID from the key generation server, encrypting a message to generate a ciphertext, and transmitting the generated ciphertext to the receiving terminal; and receiving, by the receiving terminal, the ciphertext and the private key, and decrypting the ciphertext based on the received private key to obtain a message.
