The article considers some issues of criminal law protection of information relations. With the emergence of new types of threats to Ukraine's national security in the field of protection and defense of the state border, the issues of development and strengthening of information protection become especially important. Proper compliance with information legislation also depends on the established responsibility for its violation, which rests on certain provisions of the Criminal Code of Ukraine. It is stated that these norms are placed in different sections and do not have a proper systematization. The article singles out the subjects of information relations in the border area, which are subject to criminal law protection: persons who are not bound by stable relations with the SBGS (who cross the state border of Ukraine, etc.); persons who are members of the SBGS (servicemen and employees); SBGS as a public authority (official and secret information, information about the activities of the agency, its officials, etc.).

User web service is increasing by development of internet technology. Quantity of encrypted data that transmitted through the network are increasing by development of encipherment technology. We have many problems; it is caused by technical development and service increase of user requests. It is like that, we have reliability of contents and illegality copy problem of internet contents in web application system. It is contents protection skills in web that encipherment technology, authentication and digital signature. We need message encoding and secret key for solve vulnerability of encipherment in web application system. In this paper, we propose a distributed secure system that can data confidentiality and user authentication. It prevent performance degradation from bottle neck in encipherment server, and improve service quality.

This paper proposed a model supporting secure mechanism both group communication service and subgroup communication service of TETRA system that the standard developed by the technical committee Radio Equipment and Systems(RES) of the European Telecommunications Standards Institute(ETSI) provides a pure digital information technology for the transmission of speech and data. In each scheme, members in a subgroup maintains its subgroup key, which is not distributed, but computed by each member in the subgroup only with his own secret information and public values and secure subgroup members in a same subgroup can communication securely each other by using their subgroup key. Also, all members in group can share securely a group key. In communication services of TETRA system, this model supports mechanism for both group and subgroup communication are simultaneously needed.

In case certification between user and service provider is achieved, problem that user's identity is revealed is occurring by social issue, so it was presented identity escrow scheme to solve these problem. In identity escrow scheme, the issuer who have correct user's identity transmits securely anonymity authentication information to user, and user achieves authentication phase with service provider keeping oneself anonymity using this. In this paper, we present requirement for security and trusty of identity escrow scheme and propose new mechanism that can security this. Also, propose method that service provider can deliver securely contents to user and propose mechanism that improve that support ky recovery at encryption communication that using secret key that it was generated by key agreement between users.

Purpose : This study was done to examine the home care service provided by home care nurses and the level of client satisfaction in community. Method : Data were collected from 120 clients who received the home care service at the community home care service center in Pusan from 2th May. 2003 to 31th May 2003. The tool for measurement of satisfaction was composed of 16 items and was 4 score scale by Kim. Data were analyzed by using SPSS/WIN 10.5 program. Result: 1) 67.5% among 120 clients was over sixty years old and 30.6% of clients received home visits 20 times by home care nurse. 2) The total number of home care services was 15,783. And most of the clients received therapeutic nursing care. 3) The mean score of satisfaction on provided home care services was 3.31, among 16 items, "The home care nurses kept up the secret of patients and family" was the highest($3.67{\pm}0.48$). the total level of satisfaction of home care services was very high, with mean score $3.31{\pm}0.32$. Conclusion : The satisfaction level of home care services was very high. so we can expect that the prospect of home care services is very challengeable. Therefore we should try to expand the service recipients with promotional education to assure close ties with the public health centers for the continuous home care service linking and make more efforts to improve the quality of the service.

Currently, the departments related to security and secretary service exist in 18 universities and 30 colleges in Korea in order to raise professional security and secretary personnel. Among the 18 four-year colleges in Korea, only two of them have the ethics course include in their curriculum. Also, among the 31 two-year colleges, only three of them have the ethics course included in their curriculum. Besides, as some private security and guardian companies were recently utilized in illegal actions of the rich and ruling class, contradicting their original purpose of existence, many people point out their downfall as a ?forced private army.? As a professional job, if security secretaries take advantage of the knowledge and top-secret technologies and use them for non-ethical purposes, the effect of the damage is far more serious than other fields of jobs. Therefore, taking this event as a turning point, the contract contents and the task area between the client and the security and secretary company must become more transparent in order to prevent illegal actions, and also for the people working in the security and secretary service area, it is necessary to establish a firm ethical consciousness in order to behave appropriately in their working environment. Therefore, this study examines the proper direction of work ethics of the people working in the security and secretary service according to the professionalization of their field, and also aims to propose an appropriate work ethic system such that they will not become an unfortunate victim of various scandals anymore. To do so, the concept of work ethics in professional jobs was examined; and after the code of ethics that reflect the ethical value system of each professional job was reviewed, the study suggested a specific solution for establishing the codes of ethics for security and secretary service.

The interest in cyber counseling services has been increased recently by needs and merits of cyber counseling service found through various related studies. A cyber counseling service system has not only merits but also demerits such as anonymous one-off access and difficulties of forming relations. In this study, a cyber counseling service system using class homepage was developed and implemented in order to investigate counseling methods that can enhance merits and supplement demerits of cyber counseling services. As a result, it was found that the implementation of a cyber counseling service system using class homepage can fill counseling needs of students, teachers and parents by providing various counseling methods and inducing active interaction using the site-on function. Interesting menu on class homepage was effective to lead students and parents to visit the cyber counseling room, and they prefered the secret board and counseling cases to e-mail counseling. Prior acquisition of information about students and the environment allowing teachers to continuously observe students improved counseling effects and solved problems of existing counseling services.

This paper suggests a new security architecture for facilitating secure OSGi service platform environment. The security architecture includes 1) user authentication mechanism, 2) bundle authentication mechanism, 3) key sharing mechanism, and 4) authorization mechanism. The user authentication mechanism supplies SSO(single sign-on) functions which are useful for safe and easy user authentications. The bundle authentication mechanism utilizes both PKI-based and MAC-based digital signatures for efficiently authenticating service bundles. The key sharing mechanism, which is performed during bootstrapping phase of a service gateway, supplies a safe way for sharing secret keys that are required for authentication mechanisms. Finally, the authorization mechanism suggests distributed authorization among service providers and an operator by establishing their own security policies. The main contributions of the parer are twofold. First, we examine several security requirements of current OSGi specification when its security functions can be applied in real OSGi environments. Second, we describe the ways to resolve the problems by means of designing and implementing concrete security mechanisms.

This paper deals with essentially secure group management and key transfer methods in a wireless sensor network environment. To provide an efficient security service to a widespread network with a large number of sensor nodes, the network has to be made up by several security groups, and Group Key distribution and group management are needed. In this paper we propose a mechanism for efficiently constructing and managing a security node by constructing a group using an algorithm to construct a logical group. Previous Group Key Transport method has special condition. When Base Station transports Group Key, all sensor nodes must share Secret Key with Base Station before it is intended to be deployed. Hence, we also propose a Key transport mechanism without sharing Secret Key between Base Station and sensor node.
