A security system for a programmable electronic device of a vehicle, the electronic device including an interface that can be used for accessing and/or programming the electronic device by means of an external access. The security system includes a sensor configured to detect a position and/or orientation of the electronic device with respect to the vehicle, and a security module. The security module is configured to determine coincidence based on of the position and/or orientation of the electronic device with respect to the vehicle detected by the sensor and an expected position and/or orientation of the electronic device with respect to the vehicle, and in the event of a detected coincidence prevent access and/or programming of the electronic device.

A method for securing data packets to be transmitted via an interface includes determining a check number over at least a portion of a first data packet and at least one portion of a second data packet. For this purpose, the first data packet is arranged according to a transfer protocol in a first data frame and the second data packet is arranged according to the transfer protocol in a second data frame.

Method and device for securing data packets to be transmitted via an interface

A method for monitoring a frequency signal provided within a unit is disclosed. The method comprises a step of receiving one or more binary signal levels of a cycle signal (CLK) or a control signal (CS) from a communication interface (CLK, CS, MOSI, MISO), wherein the communication interface (CLK, CS, MOSI, MISO) is designed to transfer information according to a communication protocol. The method further comprises a step of providing the frequency signal in the unit and comparing the frequency signal to a temporal sequence of signal levels of the cycle signal (CLK) received by the communication interface (CLK, CS, MOSI, MISO) in order to obtain a comparison result or controlling a counter by the control signal (CS) and the frequency signal in order to obtain a counter status. Finally, the method according to the disclosure comprises a step of recognizing a predetermined quality of the frequency signal if the comparison result fulfills a predetermined criterion or if the counter status lies within a predetermined value range in order to monitor by the recognized quality of the frequency signal.
