Cryptographically Secure PseudoRandom Bit Generator for Wearable Technology

Abstract

This paper presents a prototype wearable Cryptographically Secure PseudoRandom Bit Generator CSPRBG (wearable CSPRBG). A vest prototype has been fabricated to which an evaluation board with a ZYBO (ZYnq BOard) Zynq Z-7010 has been mounted using tailoring technology. In this system, a seed generator and block cryptographic algorithms responsible for the generation of pseudo-random values were implemented. A microphone and an accelerometer recorded sound and acceleration during the use of the prototype vest, and these recordings were passed to the seed generator and used as entropy sources. Hardware implementations were made for several selected Block Cryptographic algorithms such as Advanced Encryption Standard (AES), Twofish and 3DES. The random binary values generated by the wearable CSPRBG were analyzed by National Institute of Standards and Technology (NIST) statistical tests as well as ENT tests to evaluate their randomness, depending on the configuration of the entropy sources used. The idea of possible development of the wearable CSPRBG as a System on Chip (SoC) solution is also presented.

Aplikasi Arisan Marga Berbasis Web Menggunakan Metode Linear Congruential Generator

“…Pada penelitian terdahulu seperti Aplikasi Arisan Bangun Rumah Berbasis Web yaitu aplikasi web yang dirancang dan dibangun untuk dapat menyimpan data-data arisan untuk masyarakat Minahasa [5]. Ada beberapa algoritma pengacakan seperti Mersenne Twister dengan periode panjang namun kompleksitas tinggi, dan Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) lebih cocok untuk keamanan data [6]. Namun, untuk aplikasi arisan marga, LCG dipilih karena kecepatan, efisiensi, dan sederhana dalam implementasi, yang memadai untuk pengundian arisan dengan cara yang adil dan acak [6].…”
