Embodiment Construction
[0039] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0040] refer to figure 1 , shows the flow of the first embodiment of the distributed password recovery method of the present application, the execution subject is a distributed computer system, and the distributed computer system includes 1 service node and n computing nodes (n≧1), each The computer nodes are connected through a computer network; the computing power of the i-th node in unit time is v i ; Among them, 1≦i≦n, v i Indicates the number of passwords processed by the i-th computer node per unit time; for example, when the unit time is minutes, if v 10 =10000, indicating that the computing capability of the tenth computing node is to process 10000 passwords per minute. This preferred method e...

The invention provides a distributed password recovery method and system. The method comprises the following steps: calculating a password space according to password rule information of a password to be recovered; distributing task blocks of corresponding sizes to each calculation node in a password space range according to the password processing capability of various calculation nodes in a unit time, and triggering various calculation nodes to perform corresponding password traversal according to information of the task blocks; and distributing the task blocks of corresponding sizes to the calculation nodes completing password traversal tasks again till traversal of the password space is completed. According to the preferred embodiment, the task blocks of corresponding sizes are distributed to the calculation nodes according to the password processing capability of various calculation nodes in the unit time, such that password traversal is carried out; therefore, load balancing of different calculation nodes in a distributed environment can be ensured; furthermore, the fault-tolerant capability of the system is high; when one or more calculation nodes are abnormal, the fault recovery cost is small; and the whole performance is optimal.
Description
technical field [0001] The present application relates to the technical field of password recovery, in particular, to a distributed password recovery method and system. Background technique [0002] Brute force traversal and dictionary traversal are the two most commonly used traversal methods in password recovery. Brute force traversal is to traverse all the passwords in the rules specified by the user, and dictionary traversal is to traverse the passwords in the dictionary file. The brute force method often requires more rules to cover as large a password space as possible to improve the success rate of password recovery, but too large a password space will double the traversal time, or even take hundreds of thousands of years, making password recovery meaningless. The success rate of the dictionary traversal method is often limited by the number of passwords in the dictionary. Since the number of passwords in the dictionary is generally not too many, the password travers...
