Abstract

The large keys required by one-time pad (OTP) ciphers occupy valuable drive or other memory space. This method erases key bytes as they are used, replacing them with encrypted or decrypted data depending upon the mode of operation of the cipher. By using this method, an OTP key is replaced with new data to be stored as the key is consumed in standard cipher operations. New communications devices can each include a unique OTP transport key. A copy of each transport key is kept at a central repository. When people using any two or more of these devices wish to communicate with each other securely, one copy of a new communications key is encrypted with the transport key for device A and sent to device A and a second copy is likewise sent to device B.
