The coding device (ZA) comprises a data processing unit (1,1`) for performing cryptographic operations. A disconnecting unit (2) disengages an external data interface (IO) from an internal data interface (IB). Another interface (SV) supplies power to the coding device (ZA). A main clock signal (CLK1) is generated by a program oscillator (3) and a current profile (SP2) by another generator (4). The current profile generator (4), which switches a number of loads, comprises a further program oscillator (7) for generating an auxiliary clock signal (CLK2). |
