Secure encryption of data packets for transmission over unsecured networks

A one-time pad, comprising:

• a memory device;
• a nonrepeating, randomly ordered sequence of N numbers within the range of 1 to N within the memory device;
• and
• a plurality of arrays of random numbers within said memory device, each array within said plurality of arrays associated with a number within said sequence of numbers.

An electronic checkbook, comprising:

• a memory containing a plurality of encryption sheets, each encryption sheet within the plurality of encryption sheets including:
• a string of N numbers within the range of 1 to N arranged in a nonrepeating, randomly ordered sequence;
• and
• a plurality of random number arrays, each array within said plurality of arrays associated with a different number within said string of numbers;
• and
• a plurality of identifiers associating each encryption sheet within the plurality of encryption sheets with an electronic check.

A method of processing an electronic check, comprising:

• receiving an electronic check encrypted using a one-time pad at a business;
• transmitting a first copy of said electronic check to a payor's bank and a second copy of said electronic check to a payee's bank;
• and
• decoding said first copy of said electronic check at said payor's bank using a copy of said one-time pad.

A method of securing transmission of a global transponder location, comprising:

• receiving a request packet via a cellular communications link to said global transponder;
• encrypting a data packet containing a latitude and a longitude for a location of said global transponder using a one-time pad containing within said global transponder;
• and
• transmitting said encrypted data packet to a central computer over said cellular communications link.

A global transponder, comprising:

• a processor connected to a memory containing a one-time pad;
• a cellular modem connected to said processor and an antenna;
• a GPS chip set connected to said processor and said antenna, said GPS chip set providing GPS fix data to said processor,
• wherein said processor, responsive to receiving a call through said cellular modem, encrypts said GPS fix data using said one-time pad for transmission via said cellular modem.

A method of encrypting data packets using a one-time pad, comprising:

• selecting a character within a source data packet;
• reading a position number within a randomly ordered, nonrepeating sequence of N numbers within the range of 1 to N, wherein said position number is at a location within said sequence corresponding to a location of said selected character within said source data packet;
• reading a random number within a nonrepeating array of random numbers associated with said position number, wherein said random number corresponds within said array to said selected character;
• and
• placing said random number in a position within an encrypted data packet corresponding to said position number.

A method of decoding data packets encrypted using a one-time pad, comprising:

• reading a position number within a randomly ordered, nonrepeating sequence of N numbers within the range of 1 to N;
• reading a random number located within an encrypted data packet at a position corresponding to said position number;
• determining a character corresponding to said random number within a nonrepeating array of random numbers associated with said position number;
• and
• placing said character in a next available position within a decoded data packet.

A computer program product for use with a data processing system, comprising:

• a computer usable medium;
• first instructions on said computer usable medium for selecting a character within a source data packet;
• second instructions on said computer usable medium for reading a position number within a randomly ordered, nonrepeating sequence of N numbers within the range of 1 to N, wherein said position number is at a location within said sequence corresponding to a location of said selected character within said source data packet;
• third instructions on said computer usable medium for reading a random number within a nonrepeating array of random numbers associated with said position number, wherein said random number corresponds within said array to said selected character;
• and
• fourth instructions on said computer usable medium for placing said random number in a position within an encrypted data packet corresponding to said position number.
