The present invention discloses an application attestation server and an application attestation method. Specially, there is provided an application attestation server that attests a certain application in a smart device, the application attestation server comprising: an executable code generation unit configured to generate executable codes for attestation with respect to the application; a transceiver configured to transmit an executable code randomly selected from the generated executable codes to the smart device, and receive a result of execution of the selected executable code with respect to the application from the smart device; a malicious application analysis unit configured to analyze whether the application is a malicious application based on the received result; and an analysis result providing unit configured to provide an analysis result of the malicious application analysis unit to a user. Herein, the executable code generation unit configures to generate the executable codes by randomly combining information relevant to the application.

Server and method for attesting application in smart device using random executable code

A router is provided. The router includes a packet marking unit that inserts marking information generated based on an address of the router into a packet received by the router, according to a packet marking probability that is dynamically set, and a marking probability determination unit that calculates filtering efficiency of the router, and determines the packet marking probability based on the filtering efficiency. The marking information is used to obtain the address of the router by a device that has received the packet containing the marking information.
