Implementation of advanced encryption standard algorithm using Raspberry pi platform

The four main goals of the security services are authentication, data integrity, confidentiality, and access control. But traditionally, the algorithms of cryptographic are considered slow, requiring high computational resources and inefficiently implemented in traditional general purpose processors. The present study focused on designing and realizing the algorithm of Advanced Encryption Standard (AES) and the Security Hash algorithm (SHA-2) using LabVIEW to achieve integrity and authentication tasks. The completed hybrid cryptosystem is consisted of the combination of AES having 128,192 and 256 bits and SHA-2 having 224,256,384 and 512 bits algorithms where the SHA-2 hash code has been used as a key for AES. The algorithm was extended to the implementation of SHA-2 with AES to realize a block cipher encryption scheme appearing in the twelve output cases resulted from this security hybrid cryptosystem. In this study, the proposed hybrid cryptosystem improved the security of data to a largest and greatest extent because it provided a higher security by increasing of complexity of hardware components, which achieved by increasing the size of the hash codes of SHA-2. The largest and greatest complex design was achieved by the combination of AES-256 bit and SHA-512 bit, which produced an encrypted message of 16 bytes with encrypted hash code of 64 bytes. Finally, a mini, cheap security computer system was obtained, which produce special functions such encryption, decryption and hashing. This mini device was designed by using LabVIEW toolkit and Raspberry Pi3 minicomputer
