Encryption Technology on Windows Workstation

This paper discusses the development of a new method for encrypting text of information in
Microsoft Windows environment. The purpose of this study is to develop a new type of
encryption methodbased on RSAtechnique. In addition, the objective is to tighten the security of
Windows platform by implementing a new way of encrypting users' information to prevent
access by unauthorized users. This is achieved by trying to combine several techniques of
securing and strengthening the RSA algorithm. One of the techniques that will be looked into is
'knocking', where the authorized users will have to perform a series of predetermined actions to
validate their requests for the information in addition of the public key they have. This study is
done because current encryption method in Windows environment is quite weak (e.g.: Windows
password) and easily breakable using program like LC4(@stake LC4, about). Windows NT, 2000
and XP use Security Accounts Manager (SAM) file to store encrypted users passwords using
RSA MD4 scheme(Windows NT SAM permission Vulnerability, bulletin), so if the RSA
technique is enhanced it will enable a stronger and harder to break workstations. The result of this
study will be an enhanced version of current encryption technology that is ready to be
implemented or applied by interested parties.
