Ubirch uses Blockchain technology to secure data directly from the source of data creation, the IoT sensor. A private key located on the SIM card seals the IoT data. In the backend, these micro certificates are then stored in a so-called Merkle tree and anchored in public blockchains. This creates an unchangeable and irrefutable data set for each individual sensor. Since the protocol is bidirectional, an IoT sensor can also check incoming data packets for authenticity and integrity. This provides efficient protection against unauthorized commands or unknown sources, because IoT data can be verified whenever it is processed, and only verifiable packets are processed.
The new security package uses the proven SIGNiT solution from G+D Mobile Security, which creates the link between a proven SIM environment, a secure operating system and the block chain.
