Abstract: Disclosed are an apparatus and method for communicating data in an in-vehicle network. The method, performed by apparatuses for communicating data on a transmission side and a reception side, includes determining, by the apparatus on the transmission side, whether data collected from the in-vehicle network is changed; creating, by the apparatus on the transmission side, an authentication value based on the determination as to whether the data is changed, creating a message including the data and the authentication value and transmitting the message to the apparatus on the reception side; receiving, by the apparatus on the reception side, the message; creating, by the apparatus on the reception side, a verification value using data extracted from the message; and verifying, by the apparatus on the reception side, the integrity of the apparatus on the transmission side by comparing the authentication value extracted from the message with the verification value.

Abstract: Disclosed herein are a method and apparatus for randomizing the address space layout of an embedded system based on hardware. The method is configured such that the hardware loader of the embedded system randomly arranges the respective address regions of multiple peripheral devices and memory using a random number each time a program is loaded, such that the respective random start addresses of the multiple peripheral devices and the memory, which are set based on the randomly arranged address regions, are recorded in an address table, and such that program code loaded into the memory is reengineered based on the address table so as to match the randomly arranged address regions.

Abstract: Disclosed herein are a Desktop As A Service (DaaS) manager and DaaS client for a DaaS system. The DaaS manager includes a connection broker module, a provisioning module, a management module, and a web server module. The connection broker module permits connections to a DaaS client and a DaaS server to a user who has performed user authentication. The provisioning module determines the operating status of the DaaS server, and assigns a virtual machine of an optimum DaaS server to the DaaS client. The management module monitors the operating status of the DaaS server and the virtual machine, and executes a control command of the DaaS server. The web server module provides a web-based management tool Graphic User Interface (GUI) to the user.

Abstract: Disclosed herein are an apparatus and method for autoscaling a service shared in a cloud. The apparatus may include memory in which at least one program is recorded and a processor for executing the program, and the program may perform autoscaling by which at least one second service for performing the same function as a first service is additionally generated or deleted depending on a load that is incurred when multiple clients call the first service in the cloud. The at least one second service may be set to one of two or more execution types having different response times depending on a response time required by each of the multiple clients.

Abstract: Disclosed herein are an apparatus and method for detecting violation of control flow integrity. The apparatus includes memory for storing a program and a processor for executing the program, wherein the processor multiple branch identifier registers to which identifiers of branch targets are written, a set branch identifier instruction configured to command an identifier of a branch target to be written to a branch identifier register at a predetermined sequence number, among the multiple branch identifier registers, and a check branch identifier instruction configured to command a signal indicating detection of a control flow hijacking attack to be issued based on whether a value written to the branch identifier register at the predetermined sequence number is identical to a value of an identifier of a branch target at the predetermined sequence number, wherein the program detects whether a control flow is hijacked based on the multiple branch identifier registers.
