**A.1 Real-time applications of pipelined SMS4-BSKCryptosystem**

**Figure A1** shows the Inter-Vehicle Communication (IVC) implemented with the Pipelined SMS4-BSK cryptosystem. The communication between the vehicles is secured with the help of the proposed cryptosystem.

**Figure A2** explains a war field scenario: A short message transmission by a scout if an enemy intrusion is detected. The communication between the remote scout hub and the Army base camp is secured with the Pipelined SMS4-BSK cryptosystem.

**Figure A3** shows the secured data transmission from the Smart Glucose Bottle to a caretaker or a nurse. The data sensed by the intelligent system is transmitted with the help of Internet of Things (IoT) technology. The data is prone to hack and can make a severe threat to the life of any important persons. This worst situation can be avoided with the help of the Pipelined SMS4-BSK encryption transmission system.

**Figure A4** shows the implementation of an automatic Voice Prescription Generation and secured transmission to the patient using Pipelined SMS4-BSK cryptosystem.
