Radio Frequency IDentification (RFID) will soon become an important technology in various industries. Therefore, security mechanisms for Rm systems are emerging crucial problems in RFID systems. In order to guarantee privacy and security, it is desirable to encrypt the transferred data with a strong crypto algorithm. In this paper, we present the ultra-light weight Advanced Encryption Standard (AES) processor which is suitable for RFID tags. The AES processor requires only 3,992 logic gates and is capable of both 128-bit encryption and decryption. The processor takes 446 clock cycles for encryption of a 128-bit data and 607 clock cycles for decryption. Therefore, it shows 55% improved result in encryption and 40% in decryption from previous cases.

In this paper, we present a security tool which called Digital Legal Seal. The Digital Legal Seal scans a barcode on a paper and print it with the tag generated by Hash-based Message Authentication Code(HMAC) in text format on a display device. The result of HMAC can be used for user authentication or secure message transmission on both online and offline. We examine not only how the Digital Legal Seal can make up the weak points of security card and OTP (One Time Password), but also the possibility of reducing the forgery of promissory note on offline.

The concept of u-Vehicle is a technological model that people try to build the ubiquitous world in the car which moves, by using the RFID technology as well as the telematics service based on the location. RFID is weak on the point of information security because RFID has possibility for being abused such as chasing, counterfeiting, and invading personal privacy. RFID's tags use a weak cryptographic algorithm. This paper presents the vulnerabilities of information security under u-Vehicle environments. To solve that, we propose a mechanism enhancing RFID tag's security but with low cost by reducing the number of mutual authentication stages and using the hash function.

RFID(Radio Frequency Identification) will be used for recognizing things and offering distinctive information in Ubiquitous environment. But we are not ready to provide security service to RFID. Therefore we propose the approach of safe RFID system which provides the solution for eavesdrop, forgery, and modification based on Pre-Distribution protocol and RC5 security algorithm. First We distributes the secret key to the Tag with the Reader that is major subject on RFID system using Pre-Distribution protocol. Then we will provide to various security services and privacy protection using RC5 security algorithm. The proposed safe RFID system simulated on ATmega128 evaluate environment.

정보화 사회의 발전에 따라 컴퓨터끼리의 커뮤니케이션을 넘어 물리공간을 융합하는 유비쿼터스 기술이 발전하고 있다. 유비쿼터스를 위한 기술인 RFID는 RFID TAG가 모든 물체에 부착되어 리더와 정보를 주고받을 수 있게 된다. 하지만 RFID의 제한적인 환경으로 인해 현재 보편적으로 쓰이는 보안 기술을 사용하는 것이 어렵게 되어 유비쿼터스 시대에 맞는 새로운 보안 방법의 연구가 필요하다. 본 논문에서는 유비쿼터스 시대에 맞는 암호화 인증 기술에 방법에 대하여 연구하였다.

Smishing, Phishing personal privacy caused by Incident accidents such as Phishing information security has become a hot topic. Such incidents have privacy in personal information management occurs due to a lack of user awareness. This paper is based on the existing structure of the XML Tag question bank used a different Key-Value Structure-based JSON. JSON is an advantage that does not depend on the language in the text-based interchange format. The proposed system is divided into information security sector High, Middle and Low grade. and Provides service to the user through the free space and the smart device and the PC to the constraints of time. The use of open source Apache Load Balancing technology for reliable service. It also handles the user's web page without any training sessions Require server verification result of the training(training server). The result is sent to the training server using jQuery Ajax. and The resulting data are stored in the database based on the user ID. Also to be used as a training statistical indicators. In this paper, we design a level training system to enhance the user's information security awareness.

The essential factor of ubiquitous is security technology to properly prepare making possible network access, economic and convenient information exchange. This paper proposes an authentication protocol for RFID as one technology to realize such an ubiquitous. The proposed protocol used only the EXOR and the hash function operations reduces operations at RFID tag, which improves stability compared to existing protocols.

RFID(Radio Frequency IDentification) 기술은 리더(reader)가 RF 신호를 사용하여 물품에 부착된 전자 태그(tag)를 식별하는 비접촉 자동인식 기술이다. 그런데 여기에는 RFID 사용자의 프라이버시 보호라는 큰 문제가 존재한다. 이 문제를 해결하기 위하여 현재까지 제안되었던 보안 기법들은 태그와 리더 사이에 암호학적 기법에 중점을 두었다. 하지만, 본 논문에서는 복잡한 암호학적 기법이 아닌 개인 모바일 기기(mobile device)를 제안한다. 이것은 보호되고 있는 태그를 리더가 읽으려 할 때 태그 인식 과정에 관여하여 정당한 리더만이 태그들을 읽을 수 있도록 한다.
