Hybrid Encryption Algorithm in Wireless Body Area Networks (WBAN)

A survey on healthcare data security in wireless body area networks

“…WBAN is part of wireless sensor network in which small sensors are used to collect human’s health data and forward it towards the hospital community (Farooq 2018 ). There is need to encrypt this data before transmitting it towards medical server to achieve security.…”

“…Another approach is used in the article is to secure physical layer (PHY) transmission (Farooq 2018 ). This method secure data encryption without need of the keys.…”

“…This method secure data encryption without need of the keys. Physical Layer Security In multi hop WBAN (Farooq 2018 ) MTFG (Multi Hop Topology formation Game) algorithm is used by the sensor nodes which coordinate with each other to make a tree topology for multi hop transmission in the uplink of the WBAN. This algorithm can be deployed in the distributed way and each sensor know about the existence of its neighbors to select the best path.…”

“…We have observed that key size 128 bits is used in He ( 2017 ), Hussein ( 2016 ), Roy ( 2017 ) and Shayokh ( 2016 ) as shown in Table 4 . In Alshamsi ( 2017 ), Farooq ( 2018 ), Khan ( 2017 ), Mukhtar ( 2016 ) and Zhang ( 2018 ), key sizes large than 128 bits are also used to further strengthen the security level but it also increases the computation cost. It is also noticed that AES technique (Anwar et al 2018 ; Prameela and Ponmuthuramalingam 2016 ; Chowdhury 2018 ) and RSSI (Salehi 2016 ; Li 2017 ) used 128 bits of sizes for data and keys avoided same types of attacks which are data eavesdropping and impairments attacks but implementation of both schemes are complex and have high memory usage.…”

“…ECDH make more complex exponentiation operation (Salehi 2016 ) TEOSCC and ECDH-IBT (Mukhtar 2016 ) – TEOSCC and ECDH-IBT – Selection of cluster head is complex task and ECDH-IBT complex exponentiation operation (Mukhtar 2016 ; Salehi 2016 ) SDN (Shayokh, 2016 ; Hasan 2020 ) – Software defined Authentication (Shayokh 2016 ) Security vulnerabilities, inconsistency (Niksaz 2015 ). Network Complexity increases flow requests from SDESW (Hasan 2020 ) RMDS (Li 2016 ) – BAN-Trust Malicious node attack Trusted server can be a single point (Niksaz 2015 ) ECC (Al-Janabi 2016 ) – ECC Authentication Replay attack, insecure data communication (Anwar et al 2018 ) CCPP (Zhang 2018 ) 128–512 bits Channel aware security mechanism tempering, malevolent node attack Authentication of each node is time consuming (Zhang 2018 ) Survey (Tariq 2017 ) – 802.15.4./ZigBee – ZIGBEE technology is commonly used with low speed (Ren 2019 ) STA (Vishwakarma and Mohapatra 2017 ) – ECC – Asymmetric cryptography takes more processing time (Farooq 2...…”
