An apparatus and method for collecting digital evidence from a target system to be analyzed at a remote location and then providing security in a remote digital forensic environment based on the collected digital evidence. The method of providing security includes making, by a security providing apparatus, an evidence collection request for collection of evidence of an evidence collection-target apparatus from an evidence collection agent in a remote digital forensic environment, collecting evidence data corresponding to the evidence collection request from the evidence collection agent, verifying the evidence data based on a signature value of the evidence data collected from the evidence collection agent, generating evidence analysis data based on the verified evidence data, verifying the evidence analysis data based on a signature value of the evidence analysis data, and providing security for the evidence collection-target apparatus based on results of the verification of the evidence analysis data.

In a method of selectively applying a data encryption function, a CoAP client and a CoAP server perform a DTLS handshake process. The CoAP client generates a CoAP message when the DTLS handshake process has been completed, and then indicates that encryption does not need to be applied to the CoAP message. The CoAP client generates only the authentication value of the CoAP message via a DTLS record layer protocol. The CoAP client sets the value of the specific field of a DTLS record layer protocol header to a specific value via the DTLS record layer protocol. The CoAP client sends the CoAP message and the authentication value to the CoAP server.

An apparatus and method for transferring network access information of smart household appliances are provided. The apparatus includes a detection unit for detecting whether a public IP address of an external interface of an indoor IP sharer has changed. An extraction unit is configured to, if the public IP address of the external interface has changed, extract network access information of a smart household appliance connected to an internal interface of the indoor IP sharer, the network access information being updated together with change in the public IP address. An encryption and generation unit encrypts the network access information using a pre-stored encryption key, and generates data to be transmitted to a smart grid service provider server using the encrypted information and an ID of a customer user. A transmission unit transmits the data generated by the encryption and generation unit to the smart grid service provider server.
