We have long become accustomed to devices communicating with each other. With a smartphone, we turn on the heating and the printer orders new toner on its own. This makes security solutions for data traffic in the IoT all the more important. Predictive maintenance, constant networking, all devices automatically connected: a beautiful new world? In any case – if it is secure and nobody has to fear for their data. The more “things” are networked in the Internet of Things (IoT), the more important end-to-end security solutions become. The cycle in which data is collected, processed and passed on is already difficult to keep track of today.
Not least through digital assistance systems such as Alexa, Siri and Google Home, networking is penetrating deep into the privacy of users. The IoT also involves risks for companies, which can ultimately be much more serious than in the private sector. Sensitive data must be shared with service providers and suppliers – how do you keep control? Operational processes must not be interrupted, otherwise it not only costs a lot of money but also trust. It is very important to install a VPN on all your devices, xbox (VPNXBOX.COM), iphone (IPHONEVPN.NET), and so on.
In order to send data securely in the IoT and to minimize security risks for all users, universally applicable security solutions for data traffic must be developed that guarantee a sufficiently high level of security, can be used together with all partners in the “value chain”, but can also be implemented technically and economically with justifiable effort. But this is precisely what is currently lacking: standards.
At the same time, the market is booming, for example in the area of Smart Living: the Smart Living office of the Federal Ministry of Economics and Energy (BMWi) estimates that a global market volume of up to 30 billion euros can be expected for 2021. A volume of 4.14 billion euros is forecast for Germany. Numerous communication concepts, many of which are still proprietary, are in competition with each other.
In this dynamic environment, it is currently also the start-ups that offer solutions for secure data traffic in the IoT. Like PHYSEC, a young company based in Bochum that has already received several awards for its innovative solutions. They have specialised in applied cryptography at the IoT and are working successfully on innovative security and connectivity concepts.
The participants of the CIO Soirée were unanimous: “Without a cloud it is not possible today and in the rarest cases it is done with a single cloud. Find out how CIOs are shaping the multi-cloud.
The founders know that reliable IT security will have the greatest impact on the acceptance and further growth of the IoT market. So they developed the IoTree platform, which enables manufacturers to digitize items and connect them to the Internet. The platform also provides easy-to-use tools for truly secure encryption of this communication. The security solution focuses on creating an authentic and secure connection between the objects involved using individual cryptographic keys that are renewed regularly.
More innovation needed
For the digitization of products, processes and production, the integrity and security of data is the decisive success factor. Users – both private and commercial – rightly want complete sovereignty over their data. New business models can only be successful in the IoT if these requirements are met. In order to promote secure innovations, especially for private users, the “Founder’s Competition – Digital Innovations” of the BMWi – in which the founders of PHYSEC were also successful – has launched a special Smart Living prize.
The IoT of the future will be based even more strongly on sensors than on the fact that we ourselves monitor and control the processes in our personal environment on our smartphones. In the Smart Living area, this can be well illustrated by the simple example that the heating automatically adjusts itself when all residents have left the house.
- But the less we know that things are communicating with each other, the more we depend on it to happen safely.
- Increasingly powerful methods of artificial intelligence are available to delegate decisions from humans to machines.
- These will find their way into applications for everyone. Therefore, solutions must be found that are not only functional, but also reliably safe.
