Patent ID: 8156328

Claim:
An encryption system, comprising: generating a Vernam key via a symmetrical cipher by a hardware processor, the generating being aided by using a secret key and a variable parameter, the Vernam key having a length that is equal to a length of a message to be protected, the secret key having a defined key length, the variable parameter being a function of a random number and the defined key length; encrypting by an encryptor, via a Vernam key, the message using logic operations of a Vernam cipher; communicating, from a sending point to a receiving point, the secret key and the variable parameter via a secure channel separate from a message-transmission path; regenerating the Vernam key using the transmitted secret key and variable parameter; decrypting the message using the regenerated Vernam key; providing crypto-hardware including at least one of a chipcard and a multifunctional PC interface adapter with built-in special crypto-hardware, the crypto-hardware storing at least one generated Vernam key; utilizing the at least one generated Vernam key stored in the crypto-hardware by the encryptor; and wherein the encryptor being capable of coupling to the crypto-hardware, the encryptor includes at least one of a personal computer, software executable by a computer, and a terminal which implements a Vernam cipher for broad-band applications in software.
