Method of generating a password

摘要

For access authorisation to a processing unit, a password is usually stored in it, and compared to a password which is entered by an operator, and if the result of the comparison is positive, the processing unit is released. According to the invention, the password (PW) is generated using a criterion which changes according to a fixed scheme, e.g. the current date or day of the week, and this criterion can be linked to a calculation. Testing access authorisation to data processing systems or personal computers.
