ELECTRONIC SIGNATURE IDENTIFICATION TRNASFER METHOD THAT USES CELLULAR PHONE CHANNEL(SMS) IN P2P NETWORK

摘要

A method for transferring electronic signature certification using an SMS(Short Message Service) in the P2P(Peer-to-Peer) network is provided to prevent leakage of a key and promote the P2P by simply distributing the key through a mobile terminal and providing dual security to the distributed key. Electronic signature is performed by introducing a PKI(Public Key Infrastructure) based IBC(Identifier Based Cryptography) mode in combination of a centralized and distributed mode, and a personal certificate is issued by using WoT(Web-of-Trust) for email security of a PGP(Pretty Good Privacy) type. A private key and a public key are generated by using the electronic signature. The public key is transmitted to the mobile terminal of a receiver through the SMS. The receiver performs decryption by using the public key obtained through the SMS.
