Abstract
The present invention contemplates a secure and auditable assembly process for security keyboards which comprises a first country-independent assembly process at the security keyboard manufacturer (SKM) side resulting in country-independent assembled parts, a second and final country-specific assembly process at the ATM manufacturer side resulting in a final assembly of the country-independent parts with their appropriate country-specific layout parts to a complete security keyboard, and a final authentication process at the ATM manufacturer side for activation of the security functions of the assembled security keyboard by the authorized ATM manufacturer.
Claims20
A method for secure final assembly of a security keyboard by an assembler, the security keyboard comprising a country-independent part including a security module with a user-authentication function and a country-specific layout part, the method comprising the steps of:
- receiving a country-independent part and a country-specific layout part from a provider, together with assigned data that is encrypted using a cryptographic algorithm;
- assembling the country-independent part with the country-specific layout part to complete a security keyboard;
- decrypting the assigned data using the cryptographic algorithm;
- comparing the decrypted data with data stored in the security module;
- and
- allowing activation of the user-authentication function in the security module only if the decrypted data matches the data stored in the security module.
