Cyber attacks, (e.g., DDoS), on computers connected to the Internet occur everyday. A DDoS attack in 2016 that used “Mirai botnet” generated over 600 Gbit/s traffic, which was twice as that of last year. In view of this situation, we can no longer adequately protect our computers using current end-point security solutions and must therefore introduce a new method of protection that uses distribute...Show More

Implementation of a User Account Provisioning System Based on NFC for Public Wi-Fi Services

Yusuke Nobu;Keiji Takeda;Hirofumi Yamaki

2015 International Conference on Computer Application Technologies

Year: 2015 | Conference Paper |

HTML

For secure usage of public Wi-Fi services, mutual authentication between service providers and users is required. However, because the cost of the user account provisioning to achieve mutual authentication is high, the level of authentication is suppressed low in many services. In this research, we aim to reduce this cost. One of the problems in user account provisioning is that theft or swap of a...Show More

Intrusion Detection Systems (IDSs) play an important role detecting various kinds of attacks and defend our computer systems from them. There are basically two main types of detection techniques: signature-based and anomaly-based. A signature-based IDS cannot detect unknown attacks because a signature has not been written. To overcome this shortcoming, many researchers have been developing anomaly...Show More

Making a truly useful massively multi-agent system is difficult since the actions of the full ensemble of agents cannot be controlled by designing just one agent. It is critical to control all the agents by using protocols that describe the interaction of agents and the environment in a top-down approach.
