Summary of Reported Research:
RSA Cryptography is cryptographic algorithms that involves robust encryption/decryption processes. RSA itself is the abbreviation of its founder, Rivest-Shamir-Adleman. RSA is one of the first practical public-key cryptosystems and is widely used for secure data transmission. The writer build an RSA machine using Arduino microcontroller in this journal. The machine consists of Arduino Mega2560R3 microcontroller, external memory and a screen touch LCD and double keypad and is using  C language programming to implement the proposed RSA coprocessor with 32 bits. It was found that the trade of between message size and the encryption time can be drawn as a liner relationship according to the block size of the encryption phase. The machine is very useful for wireless sensor network (WSN). Cryptographic engineering has contributed to such cases with several algorithms to provide different levels of security for the substantial information ranges from the classical cryptosystems.

Strength of Reported Invention:
·                     It has simple configuration, and cheap to make.
·                     The system provide a reliable cryptography to secure the wireless communication.
·                     Received data can be stored in external memory (SD card).
·           Several public and symmetric key cryptographic algorithms could be designed and verified using the design sets mentioned in this paper; such as: El-Gamal Cryptosystem, Diffie-Helman Key exchange system, Data Encryption Standard (DES), Advanced Encryption Standards (AES), and many others.
Weakness of Reported Invention:
·                     The system doesnot have any portable power supply, and backup battery.
·            The design has been built only in 32-bit encryption, it still can be stretched out to higher encryption and decryption bit-size by revising and modification of the utilized algorithms.
