Abstract
The present invention relates to a cyber security method, which includes: in a first device: randomly generating an ephemeral decryption key (EDK) in response to an input of an authentication information (AI); transmitting the EDK to a third device and retrieving a token index (TI) from the third device; encrypting an ID info to generate an electronic digital signature (EDS) based on a part of the EDK to generate an authentication token (AT) accordingly; and combining the AI, the ID info, the TI and the AT to form an ephemeral string and sending the ephemeral string to a second device; and in the second device: acquiring the AI, the ID info, the TI and the AT by parsing the ephemeral string and requesting to retrieve the EDK from the third device based on the TI; and decrypting the AT and verifying the EDS based on the EDK.
