Background. With the outbreak of COVID-19, large-scale telemedicine applications can play an important role in the epidemic areas or less developed areas. However, the transmission of hundreds of megabytes of Sectional Medical Images (SMIs) from hospital’s Intranet to the Internet has the problems of efficiency, cost, and security. This article proposes a novel lightweight sharing scheme for permitting Internet users to quickly and safely access the SMIs from a hospital using an Internet computer anywhere but without relying on a virtual private network or another complex deployment. Methods. A four-level endpoint network penetration scheme based on the existing hospital network facilities and information security rules was proposed to realize the secure and lightweight sharing of SMIs over the Internet. A “Master-Slave” interaction to the interactive characteristics of multiplanar reconstruction and maximum/minimum/average intensity projection was designed to enhance the user experience. Finally, a prototype system was established. Results. When accessing SMIs with a data size ranging from 251.6 to 307.04 MB with 200 kBps client bandwidth (extreme test), the network response time to each interactive request remained at approximately 1 s, the original SMIs were kept in the hospital, and the deployment did not require a complex process; the imaging quality and interactive experience were recognized by radiologists. Conclusions. This solution could serve Internet medicine at a low cost and may promote the diversified development of mobile medical technology. Under the current COVID-19 epidemic situation, we expect that it could play a low-cost and high-efficiency role in remote emergency support.

With the rapid development of Internet technology, network and information security has become increasingly important. After studying the principle of IPSEC(IP Security) and VPN (Virtual Private Network) technology, this paper designs a network architecture which is called S1 in the TD-LTE communication system. The specific packet is securely encrypted by using IPSEC technology between the base station and security gateway. After a lot of tests, the technical solution to achieve IPSEC is proved to be realized and to have a highly efficient and stable characteristic.

The use of information technology and its use in collecting and processing data into information that is useful in decision making will play a role in determining the success of an organization or company in the future. This happened to PT. Jasa Cendekia Indonesia, the computer network that is owned has not met the needs of its employees. A good computer network is one that can serve sharing resources, data security, resources more efficiently and up-to-date information. Basically if a company can hold a computer network that serves the above for employees, of course it will make it easier for employees to do the work and improve the standards of the company itself. The proposed network built by the author for PT. Indonesian Scholar Services is a computer network built with Virtual Private Network technology. Because companies that have communication between the head office and branches that are good and safe, will be the capital for their companies in facing challenges in the era of globalization. Communication that is connected to a fast and secure computer network will make it easier for a company to supervise the activities of its company.

VoIP (Voice over Internet) dikenal juga dengan sebutan IP (Internet Protocol) Telephony saat ini semakin banyak digunakan karena memiliki beberapa keunggulan, salah satu diantaranya yaitu tarif yang jauh lebih murah daripada tarif telepon tradisional sehinggapengguna telepon dapat memilih layanan tersebut sesuai dengan kebutuhannya. VoIP dapat mereduksi biaya percakapan sampai 70%. Selain memiliki beberapa keunggulan di atas,VoIP juga memiliki kelemahan yang sangat vital yaitu dari segi keamanan transfer suarakarena berbasis IP, sehingga siapapun bisa melakukan penyadapan dan perekaman terhadap data VoIP. Ganguan yang terjadi pada sistem VoIP ada berbagai macam diantaranya, transferdata yang lewat pada suatu jaringan seperti misalnya dapat disalahgunakan (abuse), dapatdibajak isi data tersebut (sniffing), dan tidak dapat mengakses server dikarenakan server yang kelebihan muatan (Denial of Services).Ada beberapa cara untuk mengamankan komunikasi data VoIP, antara lain, dengan mengamankan jalur yang digunakan pengguna untuk melakukan komunikasi VoIP denganmenggunakan metode VPN (Virtual Private Network) dan juga dapat dilakukan suatu metode kriptografi pada aplikasi VoIP tersebut sehingga data yang dikirimkan dapat dilindungidengan baik. VPN adalah teknik pengaman jaringan yang bekerja dengan cara membuat suatu tunnel sehingga jaringan yang dipercaya dapat menghubungkan jaringan yang ada diluar melalui internet. Titik akhir dari VPN adalah tersambungnya Virtual Channels (VCs)dengan cara pemisahan. Kenyataannya koneksi sebuah end-to-end VPN tergantung dari sebuah nilai dari hubungan daripada titik-titiknya. VPN mempunyai dua metode dalampengamanan yakni IPSec dan Crypto IP Encapsulation (CIPE). Selain itu dapat dipergunakan teknik Kriptografi (cryptography) yang merupakan ilmu dan seni penyimpanan pesan, data,atau informasi secara aman.Sistem VoIP menggunakan VPN ini diharapkan dapat memberikan keamanan transfer data pada jaringan internet maupun intranet.
