Abstract
A system is described for communicating with a mobile telecommunications device (201) in a telecommunications network (207). The mobile telecommunications device (201) comprises first and second security applications. The second security application (209) is comprised in a smart card (204), typically the UICC of the mobile device (201). There is a secure logical channel between the first and second security applications which stops any malicious software resident on the device from interfering with communication between the first and second security applications. The telecommunications network (207) produces data and signals it to the mobile telecommunications device (201) which stores the data in the second security application (209) for access by the first security application (208). Typically either the second security application (209) notifies the first security application (208) when the data is stored, or, the second security application (209) sets a flag when data is stored and the first security application (208) periodically checks for the presence of the flag.
