Abstract: PURPOSE: An access control system and method is provided to secure a secrecy irrespective of an openness of a system OS, and to maintain a security against a system hacking by using a daemon determining an access authority and a security kernel performing a communication with the daemon via a character process device. CONSTITUTION: The method comprises steps of generating a packet to be requested via a system call module within a security kernel(S411), inserting the packet into a request list(S412), waking up a process sleeping at a read queue of a character process queue(S413), making the process sleep at a write process queue(S414), enabling a daemon, having an access authority and sleeping at the write queue of the character process device, to receive a request from a corresponding character process device and bring a corresponding packet from the request list(S421), checking if the corresponding packet exists at the request list(S422), if the corresponding packet exists at the request list, copying the brought packet at a user mode space(S423), if it does not, sleeping at the read queue(S424), if the security kernel wakes up a process sleeping at the read queue, instantly processing the request transmitted to the packet(S425), copying a response packet from the user space to a kernel space(S426), waking up the process sleeping at the write queue, and then executing the security kernel for receiving the result(S427), and giving back an execution result to a kernel module requesting an access control approval(S415).

Abstract: A sub security device for biometric authentication is provided to raise a security management level of a biometric authentication terminal by providing the secondary sub security device independent of the biometric authentication terminal and connected to the biometric authentication terminal. An input unit(210) receives a character string corresponding to at least one of user ID information and a command for controlling a biometric authentication terminal from the user. A processor(220) sets a communication channel for the biometric authentication terminal and transfers the command to the biometric authentication terminal. The processor includes a communication channel setter(221) setting the communication channel through mutual authentication with the biometric authentication terminal, and a command processor(222) transferring the command to the biometric authentication terminal when an instruction included in the command is within a user authority. A display driver(230) displays the character string and/or a communication state with the biometric authentication terminal. A communication port controller(240) controls a communication port for communicating with the biometric terminal.
