LoRaWAN Secure Activation Using Dynamic Identifiers

The patent introduces a true random number generator (TRNG) as an intermediary component between the hardware and the software-based pseudo random number generator. The TRNG provides high-quality random entropy that seeds the pseudo random number generator, ensuring that while the device remains software-based (low complexity), the output maintains true randomness quality (high security). This mediator approach allows the system to benefit from both simplicity and cryptographic strength.

The patent combines two different random number generation approaches - hardware-based true random number generation and software-based pseudo random number generation - into a composite system. The hardware TRNG provides the random entropy source, while the software PRNG provides the algorithmic generation capability. This composite approach leverages the strengths of both methods to achieve security comparable to hardware-based solutions while maintaining device simplicity.

The patent implements preliminary anti-action by pre-seeding the pseudo random number generator with high-quality random entropy from a true random number generator before the device is deployed or before each session. This pre-established random foundation prevents external factors (such as freezing or magnetic shielding) from later compromising the randomness quality, as the seed already contains sufficient entropy that cannot be easily manipulated or reduced by external conditions.

The patent enables the device to self-generate high-quality random numbers through an internal true random number generator that does not rely on external environmental factors. The device serves itself by generating its own cryptographic-strength random entropy through hardware-based physical phenomena (such as thermal noise or quantum effects), making it immune to external manipulation while maintaining ease of operation.
