Abstract: PURPOSE: A method for converting or inversely converting characters by encoding/compressing functions is provided to make the order of encoded results the same as the order of sentences by using indexing algorithm. CONSTITUTION: The section of a specific real number length is divided into a plurality of sections. The slope per a section corresponding to the ratio of a reference value to the length of each section is calculated. The slope per a section is multiplied by a value belonging to each section. The multiplied result is divided by a specific real number to calculate a quotient. A character is allocated according to the slope and the quotient. The character is compressed and encoded in data. The data is received. A slope per a section of the data is multiplied by the data. The multiplied result is divided by a specific real number base to calculate a quotient. The quotient is converted into a character corresponding to the slope and the quotient.

Abstract: A P2P network multiple routing method is provided to perform routing for collecting the location information of the specific file irrespective of the abnormality at a node for constructing a routing path. A first node in an m-bit identifier circle space selects the second node for transmitting the routing message in one's own finger table(S101). When a second node is selected, the first node transmits the routing message for requesting the location information of the specific files to the second node(S102). Thereafter, the first node confirms whether the transmission of the routing message fails(S103). If the transmission of the routing message fails, another node for receiving the routing message is selected in the finger table and the routing message is transmitted(S104). At the second node selection process, a key value is obtained by hashing the specific file as an object. The first node selects a node ID having the same value as one's own key value at the own finger table. The successor node having the selected node ID is selected as the second node.

Abstract: An ID(IDdentifier) verification method in peer-to-peer networks is provided to prevent forgery of an ID by securing reliability of the ID between peers in P2P network environment. A plurality of peer nodes are connected through internet. An ID verification method includes a process for verifying reliability of an ID of a second peer node(10b) by using a first peer node(10a). In the ID verification method, an ID obtaining process is performed to obtain the ID of the second peer node(101,102). An ID verification request process is performed to inspect a pseudo attack to the ID of the second peer node through a third peer node as an arbitrarily selected node by using an encryption method when an ID verification request is received from a user(103,104). A reliability verification process is performed to verify reliability for the ID of the second peer node according to results of the ID verification request process(105).
