    摘要: A block cipher ARIA substitution apparatus, the apparatus includes a first Sbox operation unit for performing operations of a substitution box S1 and a substitution box S1−1; a second Sbox operation unit for performing operations of a substitution box S2 and a substitution box S2−1; and a control unit for determining modes of the first Sbox operation unit and the second Sbox operation unit. The first Sbox operation unit has a first inverse affine transformation unit for performing an inverse affine operation for obtaining S1−1; a finite field inverse element operation unit for computing an inverse element of GF(28) or a result value of the first inverse affine transformation unit; a first affine transformation unit for performing an affine operation for obtaining S1; and a first and a second multiplexer.

    摘要: A mobile terminal and a method for controlling operation of the mobile terminal are provided. In the method, a webpage that requires input of an authentication number for user authentication is displayed and a message including an authentication number is then received upon requesting an authentication number through the webpage. The authentication number is extracted from the message and the extracted authentication number is input to the webpage to allow the authentication process to be performed. Accordingly, it is possible to quickly and easily perform login authentication information input or the user authentication process using the mobile terminal.

    摘要: Provided are an apparatus and a method for data encryption using a secure memory, and more particularly, to an apparatus and a method for high-speed, large-volume data encryption using a security function included in the secure memory in response to an encryption/decryption request of a user application program. Conventional data encryption methods perform data encryption using software or hardware including a peripheral component interconnect (PCI) bus. However, the conventional data encryption methods do not satisfy speed-sensitive applications. To improve this problem, the present invention provides an apparatus and a method for high-speed, large-volume data encryption using a security function of a memory.

    摘要: Provided are an apparatus and a method for securing internet server, including: a conformance determiner which determines whether or not packets received from a network are normal, and outputs a determination result; a rate limiter which classifies packets according to predetermined rates, and limits bandwidth; and a server global information base which contains basic information including user information and site information, and is used to determine whether or not a packet is normal, and provides basic information to the conformance determiner and the rate limiter. The apparatus and the method for securing the internet server, that are applied to a main server that provides internet service, by preventing external attacks, intrusion, or vulnerability before the internet server fails, and continuously providing normal internet service through prompt recovery when the internet server fails, in order to guarantee reliable internet service.
