Ohjelmistopohjainen etätodentaminen asioiden internetissä

When in the old days the Internet consisted mostly of workstations, servers, mainframes and networking devices, the rise of the Internet of Things has brought along smart embedded systems that are aware of their surroundings, make their own decisions and communicate with each other accordingly. These systems can be anything and anywhere from a lamp to a refrigerator. These systems require mutual trust and their integrity has to be monitored. One way to achieve this is to use attestation. Attestation is a process that is used for ensuring trust and integrity of a device. Another important factor in designing IoT devices is their cost-effectiveness. It is desirable for the devices to be cheap to manufacture so any extra hardware might become costly. One mechanism that helps to create attestation without extra hardware is to use software based attestation. The replacement of hardware attestation with software mechanisms enable faster provisioning of IoT devices to the network. One problem is that usually in IoT case the attestation traffic is communicated over insecure channels where an attacker might be listening. Another thing to be taken into consideration is the physical security, the theft of the device and its effects. One good thing of software-based attestation is the platform agnosticism
