The approach adopted for this system is based on decentralised access control. This is guaranteed by the use of an attribute based cryptographic system, represented by the MA-ABE approach (Multi-Authority Attribute Based Encryption). The result is a platform that enables an organisation’s authorities to control user access to IenIoTABEMA-ABEAccess controlDecentralised access controlThesis
