Abstract

The invention discloses a method for preventing a phishing attack for a dynamic password. The method comprises the following steps of: obtaining a unique computer identifier (ID) according to the hardware information of a computer; and establishing an authentication strategy on an authentication server, transmitting the computer ID and the dynamic password together to the authentication server when the user performs dynamic password authentication, and authenticating correspondence between the computer ID and a dynamic token sequence number according to the authentication strategy by using the authentication server. By the method, the phishing attack of a hacker for the dynamic password can be effectively prevented, and the security of online trading can be greatly improved.

Description

technical field [0001] The invention relates to a network security technology, in particular to a method for preventing phishing attacks, in particular to a method for preventing anti-phishing attacks aimed at dynamic passwords. Background technique [0002] A dynamic password is a one-time password, and each password can only be used once. The dynamic password can change with time, frequency and challenge information. The dynamic password is combined with the original static password to form a two-factor authentication, which is widely applicable to various information systems.
