Secure and Efficient Data Communication Protocol for Wireless Body Area Networks
Abstract of Secure and Efficient Data Communication Protocol
and users, whilst addressing the prevalent security and privacy concerns.
In this paper, we propose a communication architecture for BANs, and design a scheme to secure the data communications between implanted/wearable sensors and the data sink/data consumers (doctors or nurse) by employing Ciphertext-Policy Attribute Based Encryption (CP_ABE)  and signature to store the data in ciphertext format at the data sink, hence ensuring data security. Our scheme achieves a role-based access control by employing an access control tree defined by the attributes of the data. We also design two protocols to securely retrieve the sensitive data from a BAN
and instruct the sensors in a BAN. We analyze the proposed scheme, and argue that it provides message authenticity and collusion resistance, and is efficient and feasible. We also evaluate its performance in terms of energy consumption and communication/computation overhead.
In this Secure and Efficient Data Communication Protocol for Wireless Body Area Networks paper, we propose an efﬁcient attribute-based encryption and signature scheme, which is a one-to-many encryption method.
In other words, the message is meant to be read by a group of users that satisfy certain access control rules in a BAN.
Meanwhile, we design a protocol to secure the data communications between implanted /wearable sensors and the data sink/data consumers.
Our future research lies in the following directions: design a more efﬁcient encryption approaches with less computation and storage requirement (CP_ABE with constant ciphertext length), which could be better suitable for practical situations (the multi-authority CP_ABE scheme) in BAN.
