In the last few decades, information and communication technology (ICT) devices and services have become central to our lives, fundamentally changing areas such as health, communication, travel, business, and recreation. Traditional ICT systems share and store sensitive data in untrusted networks. Thus, these sensitive data must be encrypted before being uploaded to a cloud server and a fine-grained access control must be supported when sharing sensitive data.
Since the emphasis is on multi-user data sharing, and the data encryptor does not know the identities of the data users in advance, symmetric encryption, asymmetric encryption, and identity-based encryption are impractical. The attribute-based encryption (ABE) schemes are excellent for multi-user data-sharing scenarios in which the identity of the data users is unknown in advance. ABE employs an access structure based on attributes in either the ciphertext or the secret key, and it is able to provide fine-grained access control with the guarantee that a user can only decrypt a message if they satisfy the constraints imposed by the access structure.
While blockchain technology has just recently become associated with new means of managing financial assets, its possibilities are practically limitless. Blockchain is a particularly promising and revolutionary technology because it reduces risk, eliminates fraud, and provides scalable transparency for a wide range of applications. Therefore, ABE schemes based on blockchain can achieve immense number of advantages including transparency, accountability, and data immutability.
This book provides guidelines for the current research and future trends in various areas associated with ABE and its integration with blockchain applications in cloud environments so that researchers get ready reference. It is expected that researchers and readers will get adequate information on these subjects, and the book will be helpful in their research endeavors. We’ll look at the basic
