Abstract

Proof of Tunnel Signature (PoTS) is designed to avoid the main problems found in certificates based on Blockchain technology. In this case, it is so closely related to Cybersecurity. A lightweight protocol such as a Certificate Authenticated Key Agreement (CAKA) is needed to reduce the vulnerability of a system's operation, namely overcoming management overhead by using a decentralized system according to the characteristics of Blockchain Technology. PoTS is the second stage after determining the Key Agreement (KA) or certificate hash in authenticating a node, and this is also a significant step in minimizing computation costs. The nodes generated after the signing process remain anonymous and can be verified optimally. Smart contracts are also used as a support so that this research can ensure transparency and openness of transaction nodes to maintain and improve the efficiency of transaction security for a certificate based on Blockchain Technology.

Abstract

The process of making an exam card every semester change is to combine several components consisting of students, lecturers, space, time and payment. Making a test card requires time, effort and accuracy in making it and also a very long process which is around one week because it is still manual alias old school, to be able to produce an exam card from the RPU must first make an exam schedule the data is taken from OJRS + data. This research makes the broadcasting of online test cards using YII Framework. This can be a problem because there is still a risk of conflict. All of these problems can be solved by a system that can create schedules automatically or online. With this will discuss how to build an automatic scheduling application starting from needs analysis to how a scheduling problem can be solved. Keywords: Optimization, online, Test Card, bootstrap framework
