Recently a number of software and hardware Results in the emergence of a new field, LightweightĬryptography. RAM size, ROM size, register width, different operatingĮnvironment and etc. Number of new factors like limited computational power, The communication must be secured in IoT withĬonfidentiality, integrity and authentication services.

Technologies make it possible to identify physical objects andĬonnect everything to communicate and share information. It is playing a vital role inĮveryone's life by bringing physical objects and living things Now-a-days Internet of Things is a novel paradigm shift in The results show that thealgorithms Nihilist Cipher and MD5can be implemented properly so that data security can be increased because before decrypting the message, the message has to be verified first.

Furthermore, to get the original message back bydecryption Nihilist Cipher, the file verification process is first done to ensure that the file receivedhas not changed or is still original. Then the MD5 algorithm is used to get the hash value from the encrypted message. Messages or files textthat will be sent are firstencrypted using thealgorithm Nihilist Cipher. In this study, cryptographic algorithms and hash functions used are Nihilist Cipher and MD5. In cryptography the term hash one-wayfunction is widely used to test the integrity of a file. Cryptography is the science or art of maintaining data security by scrambling data or messages. The application of cryptographic techniques is one solution that can be done to overcome these security problems. On the other hand, there are problems with data security which can be disrupted by irresponsible parties such as wiretapping, destruction, data theft or other misuse. The development of information technology that is increasingly racing today makes it easy for anyone to exchange data or information.
