As part of the Java Card Forum’s 25 year celebrations, we asked ETSI SET why collaboration with the JCF has been so important over the years and what topics the 2 organisations will be working on together in the future.
By Denis Praca, Chairman of ETSI SET group
Java Card is the de-facto standard referenced by ETSI in TS 102 241 since 2004, for the support of interoperable applications on the UICC platform. Java Card is currently implemented by billions of UICCs, aka SIM cards, probably making this one of the most successful standards in the IT industry. Close collaboration between ETSI SCP, now ETSI SET, has been a key factor for this success.
With the fast growth of the eSIM market, interoperability is becoming more stringent, because of the split between the eUICC platform on one side, issued under OEMs or eUICC manufacturer control, and the Profile issued under the MNO control on the other. Java Card is playing a crucial role in providing this interoperability, allowing the MNOs to continue to deploy their favorite applications in the eSIM ecosystem.
UICC standards are still under constant evolution, in order to adapt to new use cases. ETSI SET has recently issued a new release of its specifications supporting Multiple Logical interfaces allowing the UICC to host several virtual Secure Elements coexisting logically separated and addressed independently through the same physical interface. This offers the means to embed independent identity (e.g. eIDAS), payment or transport applications in the same physical secure element as the eSIM. These new use cases require evolutions of Java Card, especially isolation and management of the different logical SEs and support of new APIs.
Beside the UICC, another technology is emerging in TC SET: the SSP platform. SSP offers more flexibility for its integration in devices with the support of various physical and logical interfaces, as well as for the deployment of secure applications no longer relying on the APDU protocol. Support from the Java Card runtime environment is the next step, for which ETSI SET expect to collaborate with the Java Card Forum.
