Abstract
The ‘things’ layer in Internet of Things (IoT) consists of a massive number of devices, many of which are power and resource constrained. Decentralized Attribute-based Encryption (DABE) provides a one-to-many scheme that fits the distributed nature of IoT, however requires extensive computation power which makes its adoption difficult. In this work, we proposed an encryption model in DABE utilizing a single node, without revealing the secrets to the outsider node. The results showed that our model significantly improved the DABE.
