Attribute-Based Encryption for the Internet of Things: A Review

The study attempts to do a thorough analysis of existing research papers, conference papers, and other pertinent publications related to Attribute-Based Encryption for IoT. Due to the variety and dynamism of connected devices and data, the Internet of Things (IoT) poses new security issues. With the aim of safeguarding IoT environments, the advanced cryptography technique Attribute-Based Encryption (ABE) facilitates fine-grained access control according to certain attributes. Traditional access control strategies frequently rely on user identities or roles, which in some circumstances can be rigid and difficult to manage. These restrictions are addressed by Attribute-Based Encryption (ABE), which allows access to data depending on certain attributes. In-depth analysis of ABE in the context of IoT is provided in this paper, starting with its foundational ideas. The review employs to locate, choose, and study the literature while providing insights into security challenges, importance of access control, ABE variants and applicability for IoT, ABE security models, ABE libraries or frameworks, and conclusion with potential future directions. This review is useful for researchers or academicians working in the field of IoT security using ABE scheme.
