Aplikasi sertifikat pada E-Learning

Perkembangan sistem komputer melalui jaringan internet semakin meningkat baik individu maupun organisasi. Internet merupakan jaringan publik keberadaannya sangat diperlukan baik sebagai media informasi dan komunikasi yang dilakukan secara bebas, menjadikan isu sekuriti sebagai hal yang perlu mendapat perhatian. Salah pemanfaatan internet adalah pada sistem pembelajaran jarak jauh atau yang lebih dikenal dengan istilah e-learning. E-Learning sebagai sistem pembelajaran jarak jauh yang dewasa ini mulai berkembang di kalangan perguruan tinggi, walaupun diakui bahwa prospek e-learning dan pembelajaran khususnya pembelajaran terbuka dan jarak jauh atau open and distance learning (ODL) melalui Internet adalah prospektif, namun masih dijumpai adanya kendala dan tantangan yang perlu mendapatkan perhatian. Saat ini banyak program-program e-learning diselenggarakan oleh kalangan perguruan tinggi. Pada sistem e-learning seringkali terjadi pemalsuan dan sulit membedakannya yang bertujuan untuk mencemarkan nama baik seseorang atau penyelenggara program e-learning. E-learning hanya dapat digunakan oleh orang yang berhak, dan untuk menghindari pemalsuan digunakan sertifikat digital dengan memanfaatkan infrastruktur kunci publik. Dalam penggunaan e-learning dibutuhkan jaminan akan kerahasiaan informasi (confidentiality), keutuhan dan keaslian informasi (integrity), keabsahan pengiriman infromasi (authentication) dan pengakuan terhadap infromasi yang dikirim sehingga tdak data disangkal (non repudiation), hal ini merupakan syarat yang mutlak dalam sistem e-learning. Certification authority (CA) adalah sebuah lembaga atau badan yang bertanggung jawab terhadap pengoperasian infrastruktur kunci publik dan pengelolaan sertifikat digital. The development of computer systems and their interconnection via the Internet has increased the dependence of both individuals and organizations. The Internet is a public network whose existence is very necessary as an information and communication medium, which is free. This, in turn, has led to a heightened awareness of security issues. One of utilization of the Internet is long-distance learning or better known as e-learning . E-learning as a system for long-distance learning started developing and being utilized in higher educational institutions. Although it has been admitted that elearning specifically open and long-distance learning or Open and Distance Learning (ODL) via the Internet has good prospects, there are still many problems and challenges that need to be addressed. The explosive growth of software to support e-learning in many institutions has created the possibility of fraud that is difficult to distinguish. In order for elearning to be used only by authorized people to avoid fraud and to ensure the security of users and e-learning websites, a system needs to be developed which separates users and servers. One technology that can meet the requirement above is digital certificates that utilize Public Key Infrastructure by using a pair of keys, a public key and private key. In e-learning, the needed assurances are that only intended recipients are able to access the appropriate information (confidentiality), that the information was not altered during transmission (integrity), that the information came from the appropriate sender (authentication), and that the sender cannot deny that the information originated from him or her (non-repudiation). Certification Authority (CA) is the third party who ensure information exchange through the Public Key Infrastructure and signs digital certificates electronically.
