Abstract: A security character string disclosure preventing method by using a fake round which provides the authentication service of one time password is provided to reduce the probability about confirming a real password. A practice frequency N is initialized from a system(S10). A system increases the round practice frequency(S20). The second character string implied with the first character string consisting of a plurality of characters corresponding to each character is submitted(S30). The specification character is inputted among the second character string(S40). Passwords corresponding character string are compared system. Authentication is performed(S70).

Abstract: An anonymity service method of a source sensor in a wireless sensor network is provided to offer the anonymity of a sensor by preventing ID information exposure of a sensor node through traffic analysis of an attacker in the network, thereby protecting the location information of a source sensor node which transmits important information. Disguise sensor node IDs are randomly generated. Sensor nodes collect disguise sensor node IDs of neighbor sensor nodes and substantial sensor node IDs of the neighbor sensor nodes during a neighbor searching process(S30). Unique values for the respective neighbor sensors are generated by using the disguise sensor node IDs(S31-S34). Data communication is performed between the sensor nodes by using the unique values and the disguise sensor node IDs(S35,S36).

Abstract: A security character string disclosure preventing method by using a pair of meaning character and a pair of the meaningless character are provided to match a pair of characters through rotation of a circle plate. The fixed security string is presented in a system(S10). The rotation of the rotation character string is used. It matches with the first character and the second character which is in the rotation character string in the fixed string and the user presses the input button(S20). A system obtains the information of the character pair matched for the target point of time. All character pairs of the security character string are completely inputted.
