Study on random unoptional graphic password scheme in computer network security protection design
In order to improve the security of computer network graphics password,the research process selects 88 password disk,sets 8 fixed unoptional position and 1 random unoptional position,establishes the corresponding password setting rules,set-ting process and unlocking process,and forms the random unoptional graphics password technical scheme.When verifying the ac-tual application effect of the password scheme,the conventional password setting mode is used as a control group to collect the pass-word setting and cracking data of network users,and compare and analyze the security and lattice probability distribution of the two password schemes.The conclusion is as follows:the scheme changes the password setting habits;compared with the conventional password scheme,the password scheme is more difficult and the security is stronger.
