A method of modulating data, which is represented by two data types of 'high' and 'low', and demodulating the modulated data, is disclosed. In a method of data modulation and demodulation for a communication system which has a transmitting end modulating a data and a receiving end demodulating the transmitted data from the transmitting end, the data is represented by two types including &#x2018;high&#x2019; and &#x2018;low&#x2019;, and the receiving end receives at least one data which consists of at least one code-word spread by a unique orthogonal code. The receiving end adds up the received data in the unit of code-word, and subtracts the length of the orthogonal code from a value which is obtained by doubling the sum of the code-word, when the code-word of the orthogonal code is &#x2018;0&#x2019;. The receiving end then averages the result after the subtraction in the unit of orthogonal code length and extracts the result, and therefore, obtains the data from the transmitting end.

Provided is a data security method and apparatus using a characteristic preserving encryption. The data security apparatus includes an interface communicating with a user terminal or a database server, an input unit receiving information, an output unit outputting information, an encryption unit encrypting data in the data security method, a storage unit storing information, and a control unit controlling functions of the interface, the input unit, the output unit, the encryption unit or the storing unit.

Data security method and apparatus using a characteristic preserving encryption

A switching device of NoC (Networks on Chip) system and a scheduling method thereof. The switching device has a switching part having a plurality of input ports and a plurality of output ports, and a scheduler for setting a transmission route between the input ports and the output ports, determining the length of code based on the number of input ports having the data among the plurality of input ports, and assigning a predetermined code of the determined code length to the input port and the output port corresponding to the set transmission route. Because the code length is adjustably varied according to the number of transmission packets, switch performance improves.

Switching device of networks-on-chip system and scheduling method thereof

An apparatus and a method for setting a routing path in System-on-a-Chip (SoC) having an n&#xd7;n net topology-based structure comprising a plurality of intellectual properties (IPs), each with a unique address, and a plurality of switches forming one-to-one correspondence to the IPs, to transmit and receive data between the IPs by using at least one of the switches. Accordingly, an orthogonal code having orthogonality is assigned according to the direction of transmission of each data (that is, output port). Then, an output port where the data is transmitted is determined, and the data is spread based on an orthogonal code assigned to the output ports of the at least one of the switches.

Apparatus and method for setting routing path between routers in chip

A method of establishing a path between routers in a system-on-chip (SoC) of n&#xd7;n mesh topology structure having a plurality of intellectual properties (IPs) each with a unique address and routers corresponding to each of the IPs respectively, including: receiving a routing packet including a hop counter, and updating address information and information of a stored routing table; establishing a path to at least one neighboring router using the updated routing table upon a request to establish the path; and delivering data by using the established path.
