  1. 10.00 - 10:30 Oscar Koeroo (KPN information security office). “Security for Remote SIM Provisioning for e-SIM”

    Abstract: Traditionally phones use SIM cards to authenticate subscribers to the mobile network. The SIM cards contain information about the home network and several authentication keys of the mobile network and the subscriber. Manufacturers are miniaturising the SIM cards to reduce costs and aid applicability in Phones and accessories. The step beyond the nano-SIM card form-factor is the complete removal of the SIM card itself and replacing it with an e-SIM, or embedded SIM. With this embedded SIM mobile network operators can load the same SIM card information dynamically into a phone. This opens up a new attack surface, by virtue of new components in mobile devices, new provisioning protocol as alternative to the physical SIM card. It also has geo-political implications, depending upon the trust model. And depending upon the architecture and assuming we also include IoT with e-SIMs it could also introduce a new business continuity risk to 60B devices globally, as per prospect of the adoption of this technology in the foreseeable future.
