abstract = {The IoT-as-a-Service (IoTaaS) business model has already been identi ed by some people from
both industry and academia, but has not been formally de ned. IoTaaS offers IoT devices on demand, with
considerable cost savings and resource optimization. In addition, it enables different applications to reuse
the existing devices. However, this business model is associated with different technological challenges that
need to be addressed, one of which is the identity problem. Focusing on this, self-sovereign identity (SSI)
schemes have proven to provide better privacy and scalability than traditional identity paradigms, which
is especially important in the IoT owing to its characteristics. In this paper, we formally analyze an IoTaaS
business model, identifying and detailing its main technological challenges. In addition, we tackle the identity
problem of this business model and propose an SSI-based identity management system, which is compliant
with the existing standards from the W3C, and include a performance evaluation.},
