Abstract: Disclosed herein are an apparatus and method for authenticating an IoT device. The method, performed by the IoT device authentication apparatus, includes transmitting, by the IoT device authentication apparatus, a random number to the IoT device and encrypting, by the IoT device authentication apparatus, the random number using a previously registered first white-box cryptography value through a white-box cryptography method; generating, by the IoT device, a first device response value from a previously registered first device challenge value using a Physical Unclonable Function (PUF) and encrypting, by the IoT device, the random number, received from the IoT device authentication apparatus, using the first device response value; and performing, by the IoT device authentication apparatus, authentication of the IoT device by checking whether the random number encrypted using the white-box cryptography method matches the random number encrypted using the PUF, which is received from the IoT device.

Abstract: Disclosed herein are an apparatus and method for device authentication. The method for device authentication based on a certificate using a PUF, performed by an apparatus for device authentication based on a certificate using a PUF, includes acquiring previously stored first Challenge-Response-Pair (CRP) information corresponding to identification information received from a device that requests authentication and generating a certificate including a public key generated using the first CRP information; transmitting a message in which the certificate encrypted using the first response value of the first CRP information as a server secret key and the first challenge value of the first CRP information are included to the device; and authenticating the device by verifying an encrypted signature message received from the device through a secure channel.

Abstract: Disclosed herein are a hardware security module, a device having the hardware security module, and a method for operating the device. The method for verifying integrity of executable code in a device includes dividing, by a Micro-Control Unit (MCU), executable code into multiple blocks, generating, by the MCU, hash values corresponding to the blocks resulting from the division, storing, by a Hardware Security Module (HSM), the generated hash values, calculating, by the MCU, at least one hash value, among hash values of the multiple blocks when the executable code boots, and comparing, by the HSM, the calculated hash value with a hash value corresponding to the calculated hash value, among the hash values stored in the HSM.

Abstract: Disclosed herein is a device equipped with flash memory, which includes memory in which at least one program is recorded and a processor for executing the program. The memory includes flash memory including a data area and a backup area, and the program divides data into two or more segments depending on whether the data can be stored in a single page and stores the same in the data area. The first segment is stored in a page along with a segment number, indicating the sequential position of the divided data, a segment offset, indicating the number of pages between the pages in which the current segment and the next segment are stored, the size of a data file name, the size of the data, and the file name. At least one additional segment may be stored in another page along with the segment number and segment offset thereof.

Abstract: Exemplary embodiments of the present invention relate to a method for generating a route between nodes in a network environment using TVWS (TV White Space). The network route generating method by PAN (Personal Area Networks) coordinator which can transmit/receive message with node existing in TMCTP (TVWS Multichannel Cluster Tree Personal area networks) through a plurality of channels belong to TVWS (TV white space), the method comprises: receiving a route search message from a SPC (Super PAN Coordinator) or an upper PAN coordinator, through a channel among the plurality of channels; and broadcasting the route search message, through the plurality of channels. According to exemplary embodiments of the present invention, a network route between nodes can be easily set using TVWS.
Abstract translation: 本发明的示例性实施例涉及一种使用TVWS（TV White Space）在网络环境中的节点之间生成路由的方法。 通过多个信道可以在TMCTP（TVWS多信道簇树个人区域网络）中存在的节点发送/接收消息的PAN（个人区域网络）协调器的网络路由生成方法属于TVWS（TV空白），该方法包括： ：通过多个信道中的信道从SPC（超级PAN协调器）或上层PAN协调器接收路由搜索消息; 并通过多个频道广播路线搜索消息。 根据本发明的示例性实施例，可以使用TVWS容易地设置节点之间的网络路由。
