Management of communication pipes in a telecommunication device coupled to an nfc circuit

Abstract

A method for detecting an attempt of diversion of a communication pipe between a port of a security module and a port of a near-field communication router present in a telecommunication device, wherein the router filters the messages addressed to said security module.

What is claimed is : 
     
         1 . A method for detecting an attempt of diversion of a communication pipe between a port of a security module and a port of a near-field communication router present in a telecommunication device, wherein the router filters the messages addressed to said security module. 
     
     
         2 . The method of  claim 1 , wherein the message comprises at least one channel identifier and one instruction code, the router comparing the instruction code with authorized codes that it contains. 
     
     
         3 . The method of  claim 2 , wherein the router compares the format of the data of the message with authorized formats that it contains. 
     
     
         4 . The method of any of  claim 1 , wherein the router comprises a table containing, for each type of control signal that may be received, an authorization or denial code. 
     
     
         5 . A method of secure transmission of data in a telecommunication device, implementing the method of any of  claims 1  to  4   claim 1 . 
     
     
         6 . A near-field communication router ( 18 ), comprising means capable of implementing the method of any of  claims 1  to  5   claim 1 . 
     
     
         7 . A telecommunication device equipped with the near-field communication router of  claim 6 .
