© 2019, International Society of Artificial Life and Robotics (ISAROB). Distributed denial of service attacks are a serious threat in the current information society, where the Internet plays an important role as infrastructure. We have been studying ways to mitigate these attacks using a method that distinguishes between legitimate users and attacks. Our previous method was not sufficient because it only analyzed access logs after the attack. In this study, we propose a new method that can distinguish between legitimate users and attacks while the services are running. When the IDS detects an attack, a quarantine server distinguishes legitimate users using access characteristics. The access characteristics are: (1) user follows links, (2) sender accessed a popular page, and (3) the sender’s current average transmission interval. Our experiments confirmed that the proposed method can distinguish between legitimate users and attacks.

© 2018 IEEE. According to the growth of troubles caused by malicious programs called bots, CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) comes to be an important role in the current information society. CAPTCHA identifies bots from legitimate human users by requiring some questions that are easy for humans to solve but difficult for bots. However, the progress of computing technology such as Optical Character Recognition (OCR) function. bots come to be able to solve present CAPTCHAs. In order to outcome such troublesome bots, more sophisticated CAPTCHA that requires the high cognitive ability of human beings is desired. In this paper, we propose a new CAPTCHA scheme that uses random dot patterns. Human beings can recognize a moving figure filled by a random dot pattern from a background that is filled by another random dot pattern; however, they lose the figure in the background when the figure pauses. Since image recognition by computer programs is usually carried out frame by frame, it is hard for bots to recognize such a moving figure filled by a random dot pattern from another random dot pattern background. The proposed CAPTCHA scheme exploits this characteristic of random dot patterns. This CAPTCHA requires users to answer a text filled by a random dot pattern that is moving on a background also filled by another random dot pattern. Several experiments were carried out to confirm that the proposed CAPTCHA scheme has enough resistance against bot attacks using representative image recognition methods. Results of the experiments showed that the image recognition methods cannot find out the answer text. Other experiments were also carried out to evaluate the usability of the proposed CAPTCHA scheme. The system usability scheme was adopted in the experiments. The obtained score was 89 that means this CAPTCHA scheme has high usability. These results showed that the CAPTCHA scheme is usable enough and has enough resistance against bot attacks.

© 2018 IEEE. With the advancement of wireless short-range technology, the number of mobile devices is also increasing. Consequently, devices often exchange information using wireless communications, but this communication has vulnerabilities, such as eavesdropping and man-in-the-middle attack. Therefore, it is necessary to perform secure pairing between devices before wireless communication begin. In this paper, we assume that devices are securely paired in limited space, such as a room using wireless communication. The method for secure pairing using Received signal strength (RSS) is simple, but RSS is easy to change due to environmental factors. Recently, pairing methods using camera and accelerometer are studied. However, these methods do not directly detect inclination of the device. We propose the one of secure device pairing method using camera and accelerometer. Our proposed method make the camera read a marker on the display of the device. The marker's inclination corresponds to the device's inclination, hence, we assume that the accuracy is higher than that of existing methods.
