Abstract: 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.

Abstract: Provided are an apparatus and a method for a low power AES cryptographic circuit for an embedded system. The apparatus and method allows each round operation to be performed in an order of an add round operation, a sub byte operation, a shift row operation, and a mix column operation in order to realize a small circuit area by making maximum reuse of designed element modules. When data is input, on the first place, operations are repeated in the above order from a first round to a round right before a last round. During a last round, only an add round key operation and a sub byte operation, and a shift row operation are performed, and then an add round key operation using a secret key is performed. At this point, each operation is performed on data by a 8-bit unit.

The network system includes a mobile node equipped with Mobile IPv6, an attendant which is accessed by the mobile node when the mobile node moves toward a new network, an AAA local server which supports AAA processes for the mobile node in a local network, an AAA home server which supports AAA processes for the mobile node in a home network, and supports initial settings during the bootstrapping of the mobile node, and a home agent which handles binding update (BU) and binding acknowledgement (BA) regarding the mobile node. The AAA home server can configure initial settings for the mobile node that is authenticated by the AAA local server so that the mobile node can be effectively bootstrapped.

Abstract: Provided are a data hashing method, a data processing method, and a data processing system using a similarity-based hashing (SBH) algorithm in which the same hash value is calculated for the same data and the more similar data, the smaller difference in the generated hash values. The data hashing method includes receiving computerized data, and generating a hash value of the computerized data using the SBH algorithm in which two data are the same if calculated hash values are the same and two data are similar if the difference of calculated hash values is small. Therefore, a search, comparison, and classification of data can be quickly processed within a time complexity of O(1) or O(n) since the similarity/closeness of data content are quantified by that of the corresponding hash values.
