Intent-Driven Attribute-Based Outsourcing Encryption Scheme

Abstract

With the development of the Internet, the communication between users is increasingly concerned about the protection of private information. As one of the important means to protect private data, attribute-based encryption takes attributes as the certificate of user decryption, which prevents private data from being leaked or tampered. However, the traditional attribute-based encryption has some problems, such as inflexible encryption process and heavy computing burden for users. We propose an intent-driven attribute-based outsourcing encryption scheme, which integrates user intent parameters into the encryption algorithm to improve the flexibility and reliability of the encryption process. Edge nodes have powerful computing and storage capabilities. We outsource some encryption and decryption operations from the users to the edge nodes, which is conducive to reducing the computing overhead of users or terminals. The hierarchical relationship of attributes can help users quickly match attributes. We construct the attributes as attribute trees, and determine the user's decryption permission according to the hierarchical relationship between user attributes. Finally, we give scheme analysis, including security proof, performance cost and functional comparison of the scheme.
