Description
The cryptographic module (called Postal Security Device, PSD) supports
booking processes within postal meters as well as value loading processes
in order to increase the postage credits. The postage credits are kept as
CSPs within the PSD. In detail the use of cryptographic services, like the
production of cryptographic keys, the encoding, decoding or signature and
signature verification is part of PSD internal purposes to the booking
processes mentioned above. The PSD uses the following algorithms in the
approved mode of operation: Triple-DES; RSA; SHA-1; RNG acc. to FIPS
186-2.
