Method for Control of Confrontation with multiple Patterns

摘要

The aim of this is to compare patterns with a Security Module with one or several Main apparatus in an environment in which the main Module has no link with a Management Center.This objective is achieved by means of a control method of pattern matching between a First device, such as a removable Security Module, and a Second device, and a Main Appliance, this confrontation with Patterns consisting of protect the exchange of Data. A Key pattern matching UniqueSaid method consisting in: verify the confrontation between both devices use patterns and patterns of Confrontation with the key only, provided that they are effected laconfrontaciu00f3n patterns previouslyIn the opposite Case; find a free position between the positions Reserved Data pattern matching in the first device and if so; to initiate a procedure deconfrontaciu00f3n patterns conveying a message contained in the second device, and C Contains an own id to this device.The Cipher is encrypted by a SECRET KEY to decrypt all the common primerosdispositivos; with the first Device this Cipher and extract the identifier of the second device; generating a Key identifier based pattern matching in this set; The First Device deconfrontaciu00f3n patterns with data with the second device.
