Perhaps you should try some spelling variations:
information authentication » authorization authentication, information communication, information application
code multidimensional » model multidimensional, choice multidimensional, modern multidimensional
authentication code » authentication codes, authentication scheme, authentication based
array string » array strong, arrays strings, array sharing
array using » arrays using

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "information authentication code multidimensional ((array using) OR (array string))~".
• Adding a wildcard symbol may retrieve word variants: information authentication code multidimensional ((array using) OR (array string))*.
