Technologies for enhancing computer security

A method of enhancing computer security by encoding at a first computer and decoding at a second computer, comprising the steps of:

• receiving a message having multiple characters from the first computer;
• transforming the message into an encrypted bit stream using a first clock having a predetermined frequency, further using a predetermined variable A, a predetermined variable B, and a predetermined variable C, wherein variable A and variable B are different from each other and are both less than variable C, and an A/B switch that automatically flips back-and-forth between a first and a second mode, the transforming including:
• converting the message into a stream of decimal digits by sequentially looking up the characters in the message within the look-up table and retrieving corresponding decimal digits for each character;
• creating an initial bit stream by converting the stream of decimal digits into binary;
• parsing the initial bit stream into subsequences that alternate between being of bit length specified by variable A, and of bit length specified by variable B, said alternating controlled by the A/B switch and the first clock and occurring according to the first clock frequency;
• padding the subsequences by inserting a quantity of preselected binary bits to the subsequences until they are each of bit length indicated by variable C;
• and
• creating a final bit stream comprising the encrypted bit stream by combining the subsequences;
• transmitting the final bit stream to the second computer;
• receiving the final bit stream at the second computer as a received bit stream and authenticating and controlling access to the second computer by:
• dividing the received bit stream into words of bit length determined by variable C,
• removing the padding from the words by removing the quantity of preselected binary bits by alternatively removing added binary bits from a word until the word is of bit length determined by variable A, and then removing binary bits from a next word until said next word is a bit length determined by variable B, said alternating occurring under the control of a second clock operating at the predetermined frequency of the first clock,
• combining the words with removed padding into an interim bit stream,
• dividing the interim bit stream into a stream of bytes,
• converting the stream of bytes into a stream of decimal digits, and
• converting the stream of decimal digits into an output message using the look-up table.
