METHOD FOR MANIPULATION PROTECTION

摘要

A method and a device for manipulation protection, including receiving a first data packet sent from a first device by a second device, the first data packet including a first time-variant parameter; signing a concatenation of a first hash value with the first time-variant parameter and an identification of the second device with the aid of a private key of an asymmetric encryption method which is assigned to the second device, program instructions or data, which are stored on the second device and provided to be carried out during the operation of the second device, being used to determine the hash value; generating a second data packet including the signature and the concatenation; and sending the second data packet from the second device to the first device.

1. A method for manipulation protection, comprising:
receiving a first data packet sent from a first device by a second device, the first data packet including a first time-variant parameter; signing a concatenation of a first hash value with the first time-variant parameter and an identification of the second device with the aid of a private key, assigned to the second device, of an asymmetric encryption method, program instructions or data, which are stored on the second device and provided to be carried out during operation of the second device, being used to determine the hash value; generating a second data packet including the signature and the concatenation; and sending the second data packet from the second device to the first device.
