发明名称 Security module and method for securing computerized postal registers against manipulation
摘要 In a data security and a security module, first and second data processing units are employed having non-volatile memories for postal register data. At a first point in time at least following letter insertion and following a check of the previously valid accounting data on the basis of an authorization code, the first data processing unit undertakes an advance calculation of the new postal register setting, which is made taking the previously set postage value into consideration, and forms a new authorization code. At a second point in time, the second data processing unit undertakes an accounting with calculation of the new postal register setting, which occurs taking the previously set postage value into consideration. A storage of the pre-calculated, new authorization code and of the new postal register set determined by the second data processing unit in the non-volatile memories subsequently ensue.
