Document Type and Number:
WIPO Patent Application WO/2010/070959
Kind Code:
A1
Abstract:
An information processing device stores: a plurality of types of security functions which define the protection attribute for each of the arguments relating to input and output of data to be protected; a program list; function argument protection attributes; and dependent relationship defined by a decision term and a dependent term which satisfy a predetermined condition.  The information processing device includes: a step of detecting a combination of a first security function in which completeness of a variable contained in the decision term of one dependent relationship is verified by a second security function and the second security function among security functions used in the process; a step of generating a third security function which gives a protection attribute for guaranteeing the completeness of the variable contained in the dependent term of the dependent relationship in the first security function if the second security function is verified successfully, without changing the action of the process; and a step of updating the function argument protection attribute and the dependent relationship accompanying the addition of the third security function.
