Wireless body area network (WBAN) consists of group of wearable devices placed inside or on the human body and wearable device controller. The devices are used to monitor and measure vital parameters, process them, transfer them to the wearable device controller. If an attacker tries to alter the information, the confidentiality of the data is lost and also it could prove fatal to the person to whom the data belongs to. The paper focuses on achieving confidentiality of the data by encrypting using the Modified Blowfish encryption algorithm. It is proved that the proposed method minimizes the encryption time by 50% as compared with Blowfish algorithm. The value calculated for avalanche of the Modified Blowfish is 48.5% and the Blowfish achieved 47.14%. Matlab is used in the research work for performing encryption of the data.
