A computing device configured to check a software key of a user terminal device. The computing device includes: an ALU, a plurality of registers having a storage capacity of at least x bits, and a data memory. The computing device is configured to perform a multiplication of two y-bit numbers each formed by a plurality of x-bit digits, as follows: loading the x-bit digits of the y-bit numbers into the registers, and repeatedly calculating, using the ALU, for all x-bit digits of the result of the multiplication of the y-bit numbers, an x-bit digit of the result based on those registers that store the associated x-bit digits of the y-bit numbers, and storing the calculated x-bit digit of the result in the data memory. Y is an integer multiple of x.

Computing device for checking a software key

A method of operating a personal safety system including a vehicle includes automatically detecting that a smartphone is within a communication range using a wireless communication system of the vehicle, and starting an approach time period with a controller of the vehicle or the smartphone when the smartphone is detected. The method further includes sending checkup data from the vehicle to the smartphone using the wireless communication system when the smartphone fails to arrive at the vehicle prior to the approach time period elapsing, and triggering an emergency response by the vehicle and/or the smartphone when the vehicle fails to receive a response to the checkup data from the smartphone within a response time period.
