The time-memory trade-off algorithm is a method for quickly inverting a one-way function,using pre-computed tables.This paper combines time-memory trade-off algorithm with Word document decryption,based on rainbow table,gives a definition of a one-way function according to the encryption mechanism of Word document,a time-memory trade-off algorithm suitable for Word document is designed.Experimental result shows that the algorithm has high performance on attacking Word document.
