A study on the implementation of a system providing reliable malware information service

Malware can be diagnosed through several ways or can even pass under the radar at times. This can cause confusion among the users, who do not welcome a flood of unorganized information in general. This paper proposes an extraction method that can provide reliable and established results in order to tackle the issue from the users’ point of view. To guarantee the reliability of Anti-virus Software (AVS) and AVS against the malware, this paper tested malware that can actually be found in use. Such processes allow this paper to extract and provide the most reliable information to users. In addition, this paper can help students, who study security, to establish the concept of malicious code. And research subjects are enough to prepare malicious code countermeasures for security graduate students.

System Design for the Safe store and Issue Service Assurance of the E-Document

Certified e-Document Authority keep it with protection legal as a system a guarantee and identifies originality of an e-Record, It presume to be authenticity e-Records and contents of an e-Record prove what was not changed. But, e-Records has high medium degree of dependence and loss danger of information has very high problems. In addition, Because correction(attachment and deletion) and a revision of information are easy, a problem for integrity and the originality of an e-Record is caused. Existing system show the following inefficient. For the originality guarantee, an existing e-Documents encryption method accomplishes a encrypted process of a whole document with a symmetric key, if the information revised midway, the whole documents content must accomplish re-scanning and re-encryption process again. To get over such inefficient, this paper maximize efficiency which occurred at the time of partial information revision request by encryption and managing using the link information based on the linkage characteristics of the each page on the registered requested e-Documents, It was able to increase security configuration by minimizing problems on an information exposure through increasing complicated of the key management.

It also increases the competitive power of the nation. With all these merits of electronic documents, there exist threats to the security such as illegal outflow, destroying, loss, distortion, etc. Currently, the techniques to protect the electronic documents against illegal forgery, alteration or removal are not enough. Until now, various security technologies have been developed for electronic documents. However, most of them are limited to prevention of forgery or repudiation. Cryptography for electronic documents is quite heavy that direct cryptography is not in progress. Additionally, key management for encryption/decryption has many difficulties that security has many weak points. Security has inversely proportional to efficiency. It is strongly requested to adopt various cryptography technologies into the electronic document system to offer more efficient and safer services. Therefore, this paper presents some problems in cryptography technologies currently used in the existing electronic document systems, and offer efficient methods to adopt cryptography algorithms to improve and secure the electronic document systems. To validate performance of proposed method compare with the existing cryptographies, critical elements have been compared, and it has been proved that the proposed method gives better results both in security and efficiency.

텔레매틱스 무선접속기술은 텔레매틱스 단말기와 텔레매틱스 서비스 사업자간 정보를 전달하기 위한 무선채널을 제공하는, CDMA 기반으로 활용되고 있다. 또한 다양한 텔레매틱스 서비스를 제공 하기 위해 DSRC, WLAN, DMB 기술이 활용되고 있다. 본 논문에서는 텔레매틱스 서비스를 제공 받 기를 원할 때 그 서비스를 제공할 서버를 발견할 수 있고 서비스 위치탐색 기능을 제공할 수 있는 MANET 이라는 환경에서 다양한 텔레매틱스 서비스를 할 수 있는 릴레이 홉 방식을 적용해서 효율 적인 텔레매틱스 서비스 전송 방식을 제안하고자 한다.

지능형 홈 네트워크 기술에 대한 도입으로 인해 인간뿐만 아니라 사물들도 컴퓨팅 및 커뮤니케이션 능력을 가지고 주변 상황을 인식하고 판단하여 인간에게 유용한 서비스를 제공하게 될 것이다. 그러나 현 실정에 있어 홈 네트워크 서비스는 단순한 가전기기 제어 관련 서비스만을 제공하고 있다. 다양하 게 변화하는 상황에 맞는 상황 적응적 서비스를 제공해야 하는 본 취지에 맞는 서비스를 제공하지 못 하고 있다. 따라서 본 논문에서는 사용자의 행위에 규칙성에 기반을 두며, 사용자 행위를 예측하여 지 능적으로 동작할 수 있는 근거를 마련할 수 있는 능동적인 서비스를 제공할 수 있는 지능형 제어 모 델을 제안하고자 한다.
