Technologies for enhancing computer security

A system comprising:

• at least one processor;
• and
• at least one memory having stored thereon computer program instructions that, when executed by the at least one processor, control the at least one processor to:
• parse a bit stream into a plurality of first access words having a first length;
• parse the bit stream into a plurality of second access words having a second length,
• the plurality of first access words and the plurality of second access words being associated with respective time periods;
• select a current password from among the plurality of first access words and the plurality of second access words based on as current time and the respective time periods;
• authenticate access to the system based on the current password,
• repeatedly replace the current password with a new current password based on changes in the current time and the respective time periods.

A non-transitory computer readable medium having stored thereon instructions for performing a method comprising:

• parsing a bit stream into a plurality of first access words having a first length, the plurality of first access words being associated with a first mode, and each of the plurality of first access words having an associated time period based on a respective position in the bit stream;
• parsing the bit stream into a plurality of second access words having a second length, the plurality of second access words being associated with a second mode, and each of the plurality of second access words having an associated time period based on a respective position in the bit stream;
• selecting a current password from among the plurality of first access words and the plurality of second access words based on a current time and a current mode;
• authenticating access based on the current password, and
• repeatedly replacing the current password with a new current password based on changes in the current mode, the current time and the associated time periods.
