Protecting your data in transit means that the privacy of your data is safeguarded all the way from the device to the cloud. The confidentially of your data needs to be ensured. Additionally, you need to be able to establish the integrity and authenticity of your data at all times. In IoT settings, which often involve thousands, if not millions, of devices, this requires highly efficient and scalable cryptographic methods.
The u‑blox end-to-end security package provides methods to encrypt and transfer every type of applicable data from the device to its own server/platform in the cloud with a few simple operations. This eliminates the need to implement a complex solution on the device microcontroller in order to establish secure communications.
u‑blox end-to-end symmetric key management system provisioning is a disruptive approach for secure key management that replaces the current public key infrastructure (PKI) approach or typical PSK systems.
The significant advantage of u‑blox E2E Symmetric KMS is that session unique keys are available out-of-the-box both in the module and in your cloud via REST API, which allows the generation of an infinite number of keys per device. Keys are uniquely tied to the hardware and can be triggered on the module side and on the server/cloud side. This entirely removes the need for creation, delivery, renewal, and revocation of certificates. Development and operations are simplified by delegating the complexity of key management to a proven scalable system.
E2E Symmetric KMS is well suited for LPWA constrained devices, optimizing secure communications to achieve up to 8x reduction in the data overhead and up to 2x the packet flights. These optimizations translate to reductions in data usage, power consumption and cost.
We believe that you should focus on your business without wasting time checking your bills. That is why we adopt a very simple pay-as-you-go approach: pay only for the services you need, for as long as you use them, without requiring long-term contracts, complex licensing or set-up fees.
An API call to u‑blox Thingstream platform is requested each time you derive a key or encrypt and transfer data to/from your device. Refer to the documentation in the "Document and resources" to learn how to use the API.
