Abstract: A method for performing a secure payment in an offline mode in an electronic device is provided. The method includes launching a secure application at the electronic device, obtaining a nonce token from an authentication unit of the electronic device, obtaining a nonce signature from a server via a network, entering an offline mode where the electronic device is disconnected from the network, encrypting, by the secure application, a user credential input by a user using the nonce token and the nonce signature, decrypting and validating, by the authentication unit, an encrypted user credential, generating a secure object based on the decrypted user credential and a random number generated by the authentication unit and performing a secure payment based on the secure object.
