Toward Security of Consumer Electronic Devices: An Advanced Attribute-Based Encryption Approach for Multimodal Fog Computing

In order to overcome the constraints of security for consumer devices, authors put forward a specialized Attribute-Based Encryption (ABE) framework designed specifically for enhancing security in fog communications. The approach presented in this study incorporates attribute-based fine-grained access control, which facilitates the encryption and decryption of data according to specified attribute-based criteria. This system guarantees that just authorized entities, whose characteristics satisfy the access policy, are able to access the data. Bilinear pairings and Decisional Diffie-Hellman key exchange are used as a means to enforce access regulations, therefore guaranteeing the confidentiality and security of data. The inclusion of attribute revocation procedures enables the alteration of user characteristics while preserving the integrity of data security. In order to ensure the security of data during transmission, secure communication protocols are used, while also taking into account the dynamic characteristics of fog situations by considering scalability and performance optimization. At the end, the proposed approach has undergone thorough validation procedure to verify its durability and effectiveness, making it a significant asset within the realm of fog computing security solutions. The results shows that the key generation time, encryption and decryption time of the proposed scheme is better than the existing approaches. Moreover, a mathematical comparative analysis is also done to prove the effectiveness of the proposed approach.
