Abstract: Provided are an electronic payment method and an electronic device using identity-based public key cryptography. The electronic payment method includes receiving, from a key management service (KMS) server that stores personal information of a user, a private key of the user generated according to an Identity-based public key cryptography (IDPKC) protocol; encrypting payment information by using a public key of a payment device being generated according to the IDPKC protocol, and encrypting order information by using a public key of a seller device being generated according to the IDPKC protocol; producing, according to the IDPKC protocol, a dual signature of the encrypted payment information and the encrypted order information by using the private key; transmitting a transaction request including the dual-signed payment information and the dual-signed order information to the seller device; and receiving a response to the transaction request from the seller device.
