Security authentication method and information security authentication equipment

Abstract

The invention discloses a security authentication method. The method comprises the following steps: randomly selecting a preset number of characters from a stored character set to form batch character sequences by information security authentication equipment according to user commands which are input in the information security authentication equipment in batches by a user through a random character sequence triggering unit, and storing the character sequences; looking up characters corresponding to PIN codes from the character sequences displayed in batches on a random character sequence display unit set in the information security authentication equipment by the user according to a preset PIN order; using position sequence numbers of the batch character sequences of the characters corresponding to the PIN codes as authentication conversion codes and transmitting the authentication conversion codes to the information security authentication equipment through a computer; and carryingout inverse operation by the information security authentication equipment so as to acquire the characters corresponding to the authentication conversion codes and carry out authentication. The invention also discloses the information security authentication equipment. By applying the invention, under the condition of not increasing a complicated input keyboard on the information security authentication equipment, the security of the authentication is guaranteed.

Description

technical field [0001] The invention relates to information security technology, in particular to a security authentication method and information security authentication equipment. Background technique [0002] Emerging e-commerce connects e-commerce operators on the network side and clients on the wireless side through the Internet, changing the operation mode of traditional commerce, greatly improving business efficiency and reducing transaction costs, but at the same time, due to the inherent Security issues, the e-commerce model is also facing more and more network security threats, once the e-commerce operation network has security problems, it will cause immeasurable losses to users and e-commerce operators. Therefore, in e-commerce applications, network security has always been considered as the most important issue. [0003] At present, e-commerce operators on the network side generally have high security due to their relatively strong material and technical streng...
