Zusammenfassung:	The present invention includes a communication module, a memory in which a data retrieval program is stored, and a processor for executing the program. At this time, the processor calculates an index corresponding to retrieval target data from the data stored in a server, based on a range and a key, upon the execution of the program, transmits the calculated index to the server, and receives the data corresponding to the calculated index from the server. In addition, the range is calculated based on permutation information received from the server and the key is set by corresponding to the data stored in the server. Accordingly, the present invention can secure stability of the data stored in the server and prevent a data leakage. 본 발명은 통신 모듈, 데이터 검색 프로그램이 저장된 메모리 및 프로그램을 실행하는 프로세서를 포함한다. 이때, 프로세서는 프로그램의 실행에 따라, 범위 및 키에 기초하여, 서버에 저장된 데이터 중 검색 대상 데이터에 대응하는 인덱스를 산출하며, 산출된 인덱스를 서버로 전송하고, 서버로부터 산출된 인덱스에 대응하는 데이터를 수신한다. 그리고 범위는 서버로부터 수신한 순열 정보에 기초하여 산출된 것이며, 키는 서버에 저장된 데이터에 대응하여 설정된다.
