Wireless body area networks (𝑊𝐵𝐴𝑁) are essential components of intelligent healthcare monitoring techniques. Especially, when the number and datatype in 𝑊𝐵𝐴𝑁 increases. In 𝑊𝐵𝐴𝑁, secure multidimensional data aggregation received a lot of attention. However, the related schemes consume more computational and communication overhead to encrypt/decrypt the multidimensional health reports. In this paper, a blockchain-assisted scalable and secure multidimensional data aggregation scheme is introduced for fog-based 𝑊𝐵𝐴𝑁. The multidimensional health data are efficiently generated, encrypted, and decrypted by using the Paillier cryptosystem. Further, the batch verification method is used to achieve efficient authentication. The proposed system offers significant security attributes with less computation and communication overhead in comparison with competing systems. Further, it supports statistical analyses such as summation and variance to analyze the received health report.INDEX TERMS Wireless Body Area Networks (𝑊𝐵𝐴𝑁), Data Aggregation, Blockchain, Healthcare Monitoring, and Paillier Cryptosystem.
