Summary:
|
According to ITU-T QSTR-SS7-DFS "SS7 vulnerabilities and mitigation measures for digital financial services transactions" unstructured supplementary service data (USSD) is a main medium in which financial fraud is being committed. Due to its clear text form and lack of authentication, fraudsters can gain unlawful access to victim's accounts and transfer money out. The purpose of this Technical Report is to examine new technologies for encryption of USSD in an end-to-end manner and estimate its applicability for integration into existing USSD technology, suggesting new recommendation and signalling requirements for the integration of such technology into the existing reference architecture. This Technical Report focuses both on the core-network end and on the user equipment (UE) end, to recommend the appropriate and most secure location for such encryption technology to be implemented. Another aspect of this Technical Report is to examine the encryption under quantum computing attacks, and to set the standard for quantum resistant encryption in telecom.
