Authentication method adopting complex cryptographic technique

Abstract

The invention provides a method for utilizing the duplex type cryptographic technique to authenticate. The method comprises the following steps that: a plurality of subcodes are appointed for a user using a password, different subcodes correspond to different sequence numbers, and all the subcodes and the sequence numbers form a duplex type password; when the authentication process is performed, the sequence of all the sequence numbers is disrupted, the disrupted sequence numbers are indicated to the user; according to the indicated sequence numbers, the user inputs the subcodes corresponding to the sequence numbers in sequence to finish the input of the password; according to the passwords inputted by the user, the identity of the user is authenticated. In the process of authenticating the password of the user, the method can realize simple operation of the user and high security.

Description

technical field [0001] The invention belongs to the technical field of cipher security, and in particular relates to a method for authentication by adopting a double cipher technique. Background technique [0002] With the rapid development of computer technology and the Internet in today's society, passwords (the passwords referred to in this article include the characteristic information extracted by numbers, fingerprints, retina, voice and other various recognition technologies, as well as the hybrids of these characteristic information.) are widely used. applied in our life. It is of great significance to protect personal privacy and corporate secrets as well as public and private property. Especially in some information that is only exchanged and released within a certain range, as well as securities and property that flow between designated individuals, etc., passwords play an irreplaceable role. [0003] At present, the scheme of password authentication widely used ...

AI Technical Summary

Problems solved by technology

[0005] 1. When the password setting is simple, it is easy to be deciphered and guessed, resulting in low security;

[0006] 2. It is easy to be forgotten when the password setting is complex and lengthy

In order to prevent the password from being deciphered, some users set the password to be complicated and lengthy, but it is difficult to remember, and there are many things that the user forgets or remembers the password incorrectly;

[0007] 3. Due to the fixedness of the password in this password scheme, the user is easily peeped and leaked during the use

Chinese patent application CN02112960.6 provides a good anti-peeping scheme, but this scheme cannot solve other drawbacks of existing encryption schemes, and also increases the complexity of operations;

[0008] 4. In this kind of password scheme, the service agency can only judge the authenticity of the password, but cannot judge the identity of the password user

If criminals use violence or other means to obtain the real password of the password user, the user's property may be lost

Chinese patent application CN01108566.5 proposes a warning scheme for this drawback, but in this scheme the victim is required to provide an emergency password when being victimized

Because this emergency password is not used at ordinary times, and the situation is very tense when being victimized, it is not easy for the victim to remember the emergency password and tell the criminals accurately, so the anti-riot effect is not very good. it is good

And this scheme also cannot solve other drawbacks of existing schemes
