The notion Internet of Things (IoT) describes the ever increasing interconnection between “intelligent” or “smart” real world objects. That is, everyday objects and machines are equipped with embedded processors, sensors and an IP-interface, which enables them to jointly perform tasks in a more efficient and convenient manner than if each device acted independently. For instance, smart home appliances can coordinate their activity periods to avoid power-consumption surges.
These efficiency gains have a flip side, namely that such smart objects might become susceptible to remote attacks by hackers or malware, if no appropriate countermeasures are employed. Thus cryptographic solutions fit for this context are needed, that on one hand side provide security but on the other are efficient enough to be deployed on such devices. This seminar will cover cryptographic techniques that were developed for this scenario such as
hierarchical identity-based encryption
cryptographic primitives with low power requirements
The seminar will cover both constructions and use-cases.
