One-Time Password Authentication Scheme to Solve Stolen Verifier Problem
One-Time Password Authentication Scheme to Solve Stolen Verifier Problem
◎伊沢亮一・森井昌克（神戸大）
One-time password schemes are simple and efficient authentication schemes, but most schemes are vulnerable to Hybrid Theft attack. In the Hybrid Theft attack, an adversary can steal the secret data from the server or can obtain the communication data. The adversary tries to impersonate a valid user using the stolen data. In this paper, we propose a new one-time password scheme against the Hybrid Theft attack.
