A vessel location validation method and apparatus are provided. The vessel location validation method includes receiving a wireless signal from a vessel, acquiring location information of the vessel from the received wireless signal, and determining whether the acquired location information is valid based on the acquired location information and a signal strength of the received wireless signal.

Method and apparatus for validating location of vessel

There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.

Anonymous authentication service method for providing local linkability

An anonymous authentication-based private information management (PIM) system and method are provided. The PIM method includes receiving an anonymous certificate not including user information from an anonymous certification authority; generating an anonymous document including the anonymous certificate and some of the user information; and providing the anonymous document to a web service provider so as to be authenticated and thus provided with a web service by the web service provider. Thus, only a minimum of user information may be provided to the web service provider. In addition, it is possible to strengthen a user's right to self-determination and control over the exposure and use of his or her personal information by allowing a user to manage his or her own personal information or entrusting the PIM server to manage user information. Moreover, it is possible to protect the privacy of a user by preventing the exposure of user information.

Anonymous authentication-based private information management system and method

An intrusion detection system and method of a wireless network providing wireless communication to one or more wireless terminal, and an intrusion detection sensor capable of detecting attacks against wireless network are provided. The intrusion detection system of a wireless network includes: an access point providing wireless communication to a wireless terminal; and an intrusion detection sensor examining packets transmitted and received between the access point and a wireless terminal according to a predetermined detection rule. The access point transmits confirmation information on whether or not an event packet, including critical information on whether or not a wireless line connection between the access point and the wireless terminal is established, is transmitted, to the intrusion detection sensor, and the intrusion detection sensor examines an event packet by using the confirmation information. According to the system and method, a variety of attacks occurring on a wireless network can be effectively detected and systematically controlled.

A server certificate verification method in a terminal during. Extensible Authentication Protocol authentication for Internet access is provided, the method including (a) receiving a server certificate from a wireless LAN authentication server, and transmitting a server certificate verification request message of the server certificate to a wireless LAN authentication server via a wireless LAN access server; (b) transmitting by the wireless LAN authentication server an On-line Certificate Status Protocol request message to an On-line Certificate Status Protocol server to verify the server certificate; (c) receiving a result of the server certificate verification performed by the OCSP server using an Extensible Authentication Protocol packet from the wireless LAN authentication server; and (d) determining whether the result of the server certificate verification is valid.
