Existing education systems are facing a threat of question paper leaking (QPL) in the exam which jeopardizes the quality of education. Therefore, it is high time to think about a more secure and flexible question sharing system which can prevent QPL issue in the future education system. Blockchain enables a way of creating and storing transactions, contracts or anything that requires protection against tampering, accessing etc. This paper presents a new scheme for smart education, by utilizing the concept of blockchain, for question sharing. A two-phase encryption technique for encrypting question paper (QSP) is proposed. In the first phase, QSPs are encrypted using timestamp and in the second phase, previous encrypted QSPs are encrypted again using a timestamp, salt hash and hashes from previous QSPs. These encrypted QSPs are stored in the blockchain along with a smart contract which helps the user to unlock the selected QSP. An algorithm is also proposed for selecting a QSP for the exam which picks a QSP randomly. Moreover, a timestamp based lock is imposed on the scheme so that no one can decrypt the QSP before the allowed time. Finally, security is analyzed by proving different propositions and the superiority of the proposed scheme over existing schemes is proven through a comparative study based on the different features.

This paper describes the online dynamic examination application plugin named "ODES", developed according to the open source software philosophy, where the CMS Wordpress is used as programmers/coders are given the potential to develop applications from scratch with safety and ease. In ODES application there exists two types of users: admin/teacher and student. The admin/teacher can create/edit/delete/view questions, categories of questions and examination papers. The questions are divided in two types, multiple choice questions (including true/false) and long answer questions (essays). The teacher can create exams choosing the number of questions and the types of questions that exist in the pool of questions that are previously created. The selection is done randomly by the application and the teacher just determines the total number of both multiple choice or long answer questions as well as the importance (weight) of each one of them (including negative grades also). The student takes the random generated exam and receives his/hers grades. The grades of the multiple choice questions are done automatically, whereas for the long answer questions the teacher is responsible to put grades on. After the completion of the exam the teacher can view the student's final score via the control panel or a report.

“…Data security is a very urgent matter and should be guaranteed in online systems that utilize public networks. Therefore, there is a need to think of a security system that can be simple for the user but on the other hand becomes hard or even impenetrable for unauthorized persons [7].…”

Nowadays the rapid development of technology can be observed in every aspect of human life, with no exception to the educational world. In particular, implementation of secure online examination system is a hot topic. Issues that should be addressed in the secure online examination system are computer and network security issues of the system and prevention of cheatings by examinees. In our paper, we provide a website application and a secure network design which can prevent cheatings by examinees, and examine both of them in aspects of security and cheating prevention.
