Abstract :
As the innovative products of Office, Office2007 and Office2010 use Open XML language to describe and ZIP to pack, and choose the SHA1-AES encryption mechanism. The paper started from the document structure, extracted the encryption information flow, and then cracked respectively the password on CPU computing computer and GPU computing platform by password brute-force method, analyzed the security of Office at last.
