Abstract: Provided are an apparatus and method for performing remote attestation by taking into account mobility. The method includes obtaining, by each node constituting a network, a remote attestation result value by performing self-remote attestation, obtaining, by each of the nodes, remote attestation result values from the other nodes by broadcasting the obtained remote attestation result value to at least one neighboring node, and monitoring, by each of the nodes, remote attestation of each of the nodes on the basis of the obtained remote attestation result values of the nodes.

Abstract: Disclosed are an apparatus and a method for Internet of Things (IoT) device security. The method includes unifying a port in a first IoT device for communication, receiving, by the first IoT device, a packet from a second IoT device through the port, identifying whether the packet in the first IoT device is in a preset packet form, verifying content of the packet in the first IoT device when the packet is in the preset packet form, and opening the port for providing a service in the first IoT device when the verifying of the packet content is successful.

Abstract: A method and an apparatus for device security verification utilizing a virtual trusted computing base are provided. The validity of a key for decryption is verified by a secure memory loader running on a processor of a device after booting of the device which is a computing device, and if the key is valid, encrypted firmware stored in a memory of the device is decrypted using the key to verify the confidentiality of the firmware. Then, the security memory loader verifies the authentication and integrity of the firmware by comparing a signature value generated for the decrypted firmware with an existing signature value.

Abstract: Provided is an apparatus and method for security control that is capable of preventing a security threat from spreading on the basis of a security control policy established for each device (or a device group) in a network infrastructure environment, such as IoT. In a network infrastructure including a service server, a gateway, and a device, the apparatus and method for security control, in response to detecting a security threat, such as distributed denial of service (DDoS) attacks, malicious code propagation, or the like, perform a security control and a security control release on a device in which the security threat has occurred and/or a device group having an identical or similar property to the device to prevent the security threat from spreading and block the security threat in an early stage.

Abstract: A method for security of an Internet of things (IoT) device includes transmitting, by a server, a key value determined based on a reliability level of a user device and a key identification (ID) of the key value to the user device, encrypting, by the user device, a command representing a service requested by a user by using the key value and transmitting the encrypted command and the key ID to the IoT device, and extracting, by the IoT device, the key value corresponding to the key ID received from the user device from pre-stored key list information, decrypting the encrypted command by using the extracted key value, executing the decrypted command to generate information requested by the user, encrypting the generated information by using the extracted key value, and transmitting the encrypted information to the user device.
