The illegal copying and redistribution of digitally-stored information is a crucial problem to distributors who electronically sell digital data. Fingerprinting scheme is a techniques which supports copyright protection to track redistributors of electronic information using cryptographic techniques. Anonymous fingerprinting schemes, differ from symmetric fingerprinting, prevent the merchant from framing a buyer by making the fingerprinted version known to the buyer only. And the scheme, differ from asymmetric fingerprinting, allows the buyer to purchase goods without revealing her identity to the merchant. In this paper, a new anonymous fingerprinting scheme based on secret sharing is introduced. The merchant finds a sold version that has been distributed, and then he is able to retrieve a buyer's identity and take her to court. And Schnorr's digital signature prevents the buyer from denying the fact he redistributed. The buyer's anonymity relies on the security of discrete logarithm and secure two-party computations.

산업화와 도시화는 엄청나게 빠른 경제 성장과 기술의 진보를 동시에 이끌어냈다. 일상생활에서도 과학적인 사실과 지식을 근거로 한 친환경적인 웰빙(well-being)형 삶이 추구되고 있다. 특히 우리가 매일 마시는 물에 대한 관심도 날로 높아지고 있는데, 문득 수돗물의 안전성을 담보하는 것이 무엇일까 생각해 보게 된다. 특히 여름철마다 댐이나 강가의 표면을 남색으로 변하게 하는 조류를 보면서...

TCP/IPv4정보보호를 위하여 본 논문에서는 사용자 인증, 전송 데이터의 기밀성 및 데이터의 무결성을 보장해 줄 수 있는 프로토콜 스택과 안전한 IP데이터그램을 제안하였다. 또한 look-up형태의 액세스 테이블을 이용해 정보보호 모듈이 있는 사용자는 물론 정보보호 모듈이 없는 사용자와도 자유롭게 정보를 교환할 수 있도록 하는 방법을 제시하였다.

과거 단순한 이동 수단이 목적이었던 자동차는 더욱 안전하고 편리한 자동차, 서비스 지향 자동차로 거듭나고 있다. 점차 편리와 안전 서비스를 제공하기 위한 전자제어 장치의 장착이 확대되고 전자제어 장치간의 연동을 통한 서비스 개발이 늘고 있으며, 이로 인해 신뢰성 빛 안전성 이슈가 최근에 많이 대두되고 있다. 본 고에서는 자동차 응용 서비스의 개발에서 IT 기술들의 집합체라고 할 수 있는 전자장치용 소프트웨어의 표준 플랫폼인 AUTOSAR의 동향과 차량 전자제어 장치의 안전성 보장을 위한 ISO 26262 표준 동향 및 이슈를 살펴본다.

In the existing air traffic management (ATM) system, various types of safety alert features are provided based on trajectory data to ensure the safety of aircraft operations, along with aircraft position and detailed flight information. The urban air traffic management (UATM) system for urban air mobility (UAM) should also provide safety alert features to ensure the safety of UAM operations. Considering the operational environment of UAM, it is necessary that the safety alert features provided at least match or exceed those available in the existing ATM system. This study aims to present the safety alert features of the new UATM system that differ from those provided by the existing ATM system before introduction and commercialization of UAM. The study was conducted focusing on the safety alert features that should be provided in the event of a deviation from the UAM's path, and the establishment of the safety alert features was carried out in two parts: approach path monitor (APM), which is applied during the approach phase, and route adherence monitoring (RAM), which is applied during the cruise phase.

Forward secrecy in an e-mail system means that the compromising of the long-term secret keys of the mail users and mail servers does not affect the confidentiality of the previous e-mail messages. Previous forward-secure e-mail protocols used the certified public keys of the users and thus needed PKI(Public Key Infrastructure). In this paper, we propose a password-based authenticated e-mail protocol providing forward secrecy. The proposed protocol does not require certified public keys and is sufficiently efficient to be executed on resource-restricted mobile devices.
