An Efficient Two-Factor Authentication Scheme Based on the Merkle Tree
Sensors, 2020 The Time-based One-Time Password (TOTP) algorithm is commonly used for two-factor authentication. In this algorithm, a shared secret is used to derive a One-Time Password (OTP). However, in TOTP, the client and the server need to agree on a shared secret
