Abstract

The invention provides a setting method of a graphical password of a communication terminal. The method comprises the steps of setting a group of loading pictures, establishing an ID (identifier) of each loading picture, generating a grid interface with multi-character input when the communication terminal receives a graphical password setting instruction and judges that no password is set previously, randomly filling the grid interface with characters, performing encryption operation on the input characters, allowing an encryption result to correspond to the IDs of the loading pictures, converting a character password into the IDs of the loading pictures, and performing storage to complete password setting. According to the method, the pictures serve as the password, so that a user is provided with convenience, complicated character input is avoided, and the user is not required to memorize many character passwords, but only selects the more visual pictures.

Description

A kind of communication terminal graphical passwords method to set up
Technical field
The present invention relates to a kind of communication terminal cipher application technology, particularly a kind of communication terminal graphical passwords method to set up.
Background technology
For a long time, in the middle of cipher authentication system, the most popular cryptogram form of people is letter, numerical ciphers, namely by the combination of one group of letter and number as password, by submitting to this password to reach the object proving oneself identity to system or other people.
But, just as this method bring conveniently simultaneously, it also faces a lot of problem.Usually for the consideration of security, system requirements user uses the password being difficult to be cracked, but user is in order to easy to use, and tendency shortens Password Length or uses the password be familiar with.This brings fatal problem with regard to giving the security of password, and the various methods of assailants usually by comprising Brute Force, dictionary attack etc. crack the password of user, steal other people various information.D.Klein points out, uses one and comprises 3,000, and namely the dictionary of 000 word can crack in the middle of 14000 passwords 1/4.And E.Spafford also points out, only use the online dictionary of 1988UNIX to add 432 words again as dictionary, the password of 50% website can be cracked.The computing chip computer speed of now is accelerated again and again, makes more complicated attack dictionary to be applied in password cracking easily, cracks speed and but can shorten again and again.
Based on above various reasons, graphical passwords arises at the historic moment.It is a kind of brand-new cryptographic system, and use figure etc. are as medium, and user, when authentication, needs to carry out certain operation to these figures.Because the password space of graphical passwords is comparatively large, application mode is flexible, does not use the features such as word, and make it to Brute Force and dictionary attack immunity, in addition, some graphical passwords systems can prevent shoulder from peeping completely.
Summary of the invention
The object of the present invention is to provide a kind of method and device of communication terminal graphical passwords, the lower problem of conventional characters cipher safety can be solved better.
A kind of communication terminal graphical passwords method to set up, comprising:
Arrange one group Load Image and set up each ID that Loads Image;
Communication terminal receives and arranges graphical passwords instruction, and when not arranging password before judging, generates the grid interface with the input of multiple character, and be filled in grid interface by random for character;
Computing is encrypted to institute's input character and encrypted result is corresponding with the ID that Loads Image, character password is converted to the ID storing of Loading Image, completes password and arrange.
Adopt said method, graphical passwords instruction is set when communication terminal receives, and before judging when character password is set, to institute's input character be encrypted calculate and by encrypted result and each ID that Loads Image corresponding, character password is converted to the ID storing of Loading Image, completes password and arrange.
Adopt said method, when communication terminal receives, graphical passwords instruction is set, and when before judging, gesture password is set, character corresponding to each node of gesture password is set and stores the node of gesture process, the character corresponding to the node of gesture process is encrypted and calculates and the ID that encrypted result and each to be Loaded Image is corresponding, character password is converted to the ID storing of Loading Image, completes password and arrange.
The present invention compared with prior art, has the following advantages: (1) compares character arrangements memory, and figure exists a large amount of memory points, is more prone to memory; (2) character password quantity is few, easily cracks, and a graphical passwords takies multiple grid in communication terminal, can form the password of magnanimity between different figures, decodes suffering.
Below in conjunction with Figure of description, the present invention is described further.
