Abstract
A method and a device for data encryption in programming of control units is described. In this method, the data to be transmitted is encrypted byte by byte with a first key in a programming unit and then transmitted to a control unit via a data line. Then the data is decrypted in the control unit by using a second key which is provided in the control unit.
Claims16
A method of data encryption in programming of a control unit comprising:
- encrypting data to be transmitted in a programming unit using a first key;
- transmitting the encrypted data to the control unit via a data line;
- and
- decrypting the encrypted data in the control unit using a second key provided in the control unit.
A data encryption system, comprising:
- a programming unit in which a first key is provided;
- a control unit in which a second key is provided;
- and
- a data line coupled to the programming unit and the control unit for transmitting encrypted data.
A computer program for execution on a computing unit, the computer program comprising:
- a program code arrangement for performing an encryption in accordance with a table and a hash function.
A computer program for execution on a company unit, the computer program comprising:
- a program code arrangement for performing a decryption in accordance with a table and a hash function.
A computer-readable medium, comprising:
- a program code arrangement for performing an encryption in accordance with a table and a hash function.
A computer-readable medium, comprising:
- a program code arrangement for performing a decryption in accordance with a table and a hash function.
