Possibly you would not think of your municipality as a wise town, however, every day more and more urban spaces have compatibility with the description. Smart villages have digitized processes, iotized knowledge flows, and a variety of interconnected networks. They have this. knowledge-based base to manage the functions of the city, percentage of data between agencies and with the public, and essential supply for citizens.
In particular, today’s cities rely on the generation, capture, and movement of knowledge to manage critical infrastructure. This includes the distribution of electric power and herbal fuel, water and wastewater management, lighting fixtures and traffic control, law enforcement and public safety, hospital operations, and public health. and the provision of social and fitness services. In other words, there is a lot of traffic on urban networks.
But how secure is knowledge in those networks?As city IT managers know, their virtual infrastructures are increasingly threatened by cyberattacks. Ransomware has hit cities harder than other government sectors. after the war in Ukraine.
The good news is that there is an effective way to protect critical municipal infrastructure, and that is with a small form element or lightweight data encryption. Powered through the open TDF (Trusted Data Format) standard, lightweight encryption can be incorporated into the systems and programs that agencies already use today, allowing a city to protect critical infrastructure data throughout its lifecycle, without disrupting existing workflows.
Encryption doesn’t have to replace the functioning of cities; it simply gives them more information that already enters and leaves their generation ecosystem, allowing data to be temporarily transmitted with more security and confidence.
Small-scale encryption for devices
Data encryption applies mathematical algorithms to encode knowledge so that it can only be read by someone who has the unique key to decrypt it. It provides a very effective form of knowledge when it is at rest on a device or in a knowledge base and when it is on the move, crossing a network.
The potential problem is that encryption can increase the size of records. This poses two problems for smart cities. The first is that the small sensors at the edge of the network have limited computing power. The other is that most remote wireless networking technologies used across municipalities have very limited bandwidth.
The answer to those disorders is lightweight encryption, which encrypts data packets without increasing their size too much. Effective lightweight encryption provides the full data coverage force of popular encryption, only suitable for the smallest data packets found in critical infrastructure networks.
The most productive way for cities to get lightweight encryption is to use an open, government-approved standard. the seller withdraws the support.
This is where TDF comes in. TDF is an open format for coverage of sensitive knowledge, supported by the Office of the Director of National Intelligence and widely used by the U. S. intelligence community. UU. La generation applies military-grade 256-bit encryption to wrap the knowledge elements in a layer of security and privacy.
Agencies can combine this encryption with attribute-based control. ABAC allows to know by evaluating the attributes or characteristics of the applicant. This is a next-generation authorization style because it’s more accurate than classic role-based control. ABAC can take into account a mix of attributes and can be dynamically adjusted to comply with conversion regulations.
Combining encryption with ABAC protects knowledge throughout its lifecycle. Agencies retain control over how knowledge is accessed, regardless of where it is shared, as long as knowledge exists.
Microfibering, macro benefits
Why is TDF ideal for smart cities? Because it is available in a lightweight binary variant that minimizes encryption and ABAC with a payload of only 42 bytes. This is well below the typical communication network limit of 250 bytes. Encrypted knowledge packets pass through the network with virtually no latency.
Lightweight encryption is suitable for any smart use case where knowledge wants to go from the edge to the core. The implementation of lightweight encryption means agencies no longer have to worry about security features built into edge devices, even if they were built with legacy. libraries that have known vulnerabilities. With encryption and ABAC implemented at the level of the knowledge object, it doesn’t matter if hackers enter the device or network as they still can’t read the knowledge.
As more municipalities adopt smart city technologies, it will become increasingly important to ensure knowledge of critical infrastructure. Lightweight and effective encryption can ensure that knowledge bodies collected on remote sensing are never altered, from the moment it is generated until it is stored on servers or shared with stakeholders, as long as knowledge exists.
