Secure Authentication

To send data over the network, devices need to authenticate themselves within the network. After authentication, the device will be able to send the data in-network. After authentication, secure communication of devices is an important task that is done with an encryption method. IoT network devices have a very small circuit with low resources and low computation power. By considering low power, less memory, low computation, and all the aspect of IoT devices, an encryption technique is needed that is suitable for this type of device. As IoT networks are heterogeneous, each device has different hardware properties, and all the devices are not on one scale. To make IoT networks secure, this paper starts with the secure authentication mechanism to verify the device that wants to be a part of the network. After that, an encryption algorithm is presented that will make the communication secure. This encryption algorithm is designed by considering all the important aspects of IoT devices (low computation, low memory, and cost).

The security and confidentiality of information becomes an important factor in communication, the use of cryptography can be a powerful way of securing the information, IDEA (International Data Encryption Algorithm) and WAKE (Word Auto Key Encryption) are some modern symmetric cryptography algorithms with encryption and decryption function are much faster than the asymmetric cryptographic algorithm, with the combination experiment IDEA and WAKE it probable to produce highly secret ciphertext and it hopes to take a very long time for cryptanalyst to decrypt the information without knowing the key of the encryption process.

<p>ABSTRAK <br /> <br />Masalah keamanan dan kerahasiaan data merupakan hal yang sangat penting dalam suatu organisasi maupun pribadi. Apalagi kalau data tersebut berada dalam suatu jaringan komputer yang terhubung/terkoneksi dengan jaringan publik misalnya internet. Tentu saja data yang sangat penting tersebut dilihat atau dibajak oleh orang yang tidak berwenang. Sebab jika hal ini sampai terjadi kemungkinan data kita akan rusak bahkan bisa hilang yang akan menimbulkan kerugian material yang besar. Pada tulisan ini akan dibahas sistem keamanan pengiriman pesan/data dengan menggunakan penyandian yang bertujuan untuk menjaga karahasiaan suatu pesan dari akses orang-orang yang tidak berwenang/ berhak. Karena sistem keamanan pengiriman ini sangat luas cakupannya maka pada bagian ini dibatasi hanya menguraikan Kriptografi menggunakan Algoritma IDEA dan fungsi hash yang meliputi proses enkripsi, dekripsi. International Data Encryption Algorithm (IDEA) adalah metode enkripsi yang dapat diandalkan diantara metode-metode lain yang ada saat ini. Kriptografi IDEA menggunakan key 128-bit dan block plaintext 64-bit sehingga record yang dienkripsi cukup aman.Dengan menggabungkan metode enkripsi IDEA (International Data <br />Encryption Algorithm) untuk mengenkripsi isi pesan/data dan fungsi hash untuk mengetahui adanya perubahan terhadap isi pesan/data diharapkan tingkat keamanan menjadi lebih baik. Hasil dari penelitian ini berupa sebuah perangkat lunak yang mampu melakukan enkripsi dan dekripsi terhadap pesan/data, men-generate security key berdasarkan pesan/data yang dienkripsi.</p>
