Prof, Dept. of ECE, Siliguri Institute of Technology, Sukna, Siliguri, West Bengal, India 1 Network Engineer, Network Dept, Ericsson Global India Ltd, India2 Abstract:-. The Secure Internet Live Conferencing (SILC) protocol, a new generation chat protocol provides full featured conferencing services, compared to any other chat protocol. Its main interesting point is security which has been described all through the paper. We have studied how encryption and authentication of the messages in the network achieves security. The security has been the primary goal of the SILC protocol and the protocol has been designed from the day one security in mind. In this paper we have studied about different keys which have been used to achieve security in the SILC protocol. The main function of SILC is to achieve SECURITY which is most important in any chat protocol. We also have studied different command for communication in chat protocols. Keywords: SILC protocol, IM, MIME, security I.INTRODUCTION SILC stands for “SECURE INTERNET LIVE CONFERENCING”. SILC is a secure communication platform, looks similar to IRC, first protocol & quickly gained the status of being the most popular chat on the net. The security is important feature in applications & protocols in contemporary network environment. It is not anymore enough to just provide services; they need to be secure services.

International Journal of Business and Management Review Vol.6, No.7, pp.47-57, August 2018 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) RELATIONSHIP BETWEEN FILE TRANSFER PROTOCOLS ASSISTED KNOWLEDGE-SHARING AND ORGANIZATIONAL EFFECTIVENESS Dr. (Mrs.) A. E. Bestman and Mr. H. Wogboroma Department of Office and Information Management, Faculty of Management Sciences, Rivers State University ABSTRACT: The study investigated relationship between File Transfer Protocols assisted knowledge-sharing and organizational effectiveness. Two research questions and a hypothesis were designed to guide the study. The population comprised all the medical personnel in the University of PortHarcourt Teaching Hospital, Rivers State. The sample of the study consisted of 80 medical personnel of whom 30 were medical doctors and 50, randomly drawn from the population. The instrument for data collection was a questionnaire code-named Relationship between File-Transfer-Protocol Assisted Knowledge Sharing and Time Wastage Prevention Assessment Questionnaire (RFTPAKSTWPQ). The fool test for the internal consistency of the instrument was conducted using Cronbach aphc statistical. Mean and standard deviation were used to analyzed the results with the aid of z-test. Results revealed that file transfer-protocol- assisted knowledge sharing relates to prevention of time wastage in treating the in-patients in Federal Government-owned hospital in PortHarcourt, Rivers State and no relationship exists between knowledge sharing -
