Tiempo Secure joins nuSIM Partnering Network

Deutsche Telekom has listed Tiempo TESIC Secure Element as a dedicated hardware enclave in it’s latest nuSIM Security specification. nuSIM is an integrated SIM solution for IoT developed by Deutsche Telekom in cooperation with industry partners for chipsets, modules and digital security.

The nuSIM security certification refers to Common Criteria security standards and reduces time-to-market and lowers entry barriers for NB-IoT.
Tiempo is a Secure Element IP partner for SoC (System-on-a-chip) developers. The company helps these customers to reduce time-to-market and to lower entry barriers by integrating its CC EAL5+ and EMVCo certification-ready TESIC Secure Element as IP macro directly into their IC-designs. This allows access to two market segments:

  • Low-cost NB-IoT devices, that are used in mobile IoT applications with a long life-span such as asset trackers, smart motion or temperature sensors and wearables
  • High-end IoT devices, requiring CC EAL5+ and/or EMVCo certifications. Such use-cases include automotive, industry 4.0, payment, etc.

For both markets Tiempo co-operates with major SIM software stack providers. For low-cost NB-IoT devices, Tiempo now supports Deutsche Telekom’s nuSIM specification. It optimizes the SIM function while keeping a high security level through a dedicated security certification, compatible with the cost-sensitive mobile IoT market.

nuSIM will simplify IoT devices as it eliminates the need for a separate SIM component. The solution provides a very low hardware and software footprint for cost-efficient implementations with minimal power consumption, but without compromising on security,

said Stefan Kaliner, Head of UICC Development at Deutsche Telekom.
In a nuSIM implementation, the Secure Environment can be realized on a dedicated hardware enclave integrated with the other components of the SoC on the same die. It contains a dedicated processor, crypto-processors, security sensors and memories for exclusive use within the secure enclave.

Especially for low-cost devices this brings simplicity as well as cost and time savings along the IoT value chain,

adds Serge Maginot, CEO of Tiempo Secure.

All our customers targeting security-critical device markets continue to go for CC EAL5+ and/or EMVCo certifications. Many see the nuSIM approach as a perfectly logical step and a chance for a first and faster entry to the NB-IoT market.
