Abstract

A public key cryptography (PKI or other similar system) is used to sent partial or multiple of encryption or decryption algorithm (cipher or decipher) to the data sender or receiver to encrypt or decrypt the data to be sent or received and destroy itself after each or multiple use. Since the encryption algorithm is protected, it can be devised very small in size in compare to the data to be sent and the user can afford to use large key size in it'"'"'s transmission to increase protection without significant compact to the overall speed. Without knowing the encryption algorithm, which may also be changing from time to time, it will be impossible to use brut force to break the code provided that the algorithm scheme is designed properly. It is due to that there are unlimited numbers of new or old algorithms with countless variations and it takes years of supper fast computing time to break even few algorithms. Under this condition, many fast encryption algorithms can be easily devised for use, thus speed and safety can be greatly enhanced.

Claims

1. A method of encrypting and sending data from a sender to a receiver, comprising:

said sender uses an encrypting/decrypting device to encrypt a sender-selected decipher (E-decipher) by a public key (PKI) cipher with a public key and send said encrypted E-decipher to said receiver wherein said E-decipher is designed to decrypt data encrypted by a sender-selected cipher (E-cipher) of said sender and said E-cipher is designed to encrypt data to be sent by said sender;

said sender or said receiver applies said E-cipher or said E-decipher, respectively, to carry out a session of encrypted data transmission;

said sender or said receiver applies said E-cipher

or said E-decipher, respectively, to carry out the session of encrypted data transmission further comprising a step of using a random data in a code page as a scramble and unscramble template,

wherein said E-cipher and said E-decipher include only exclusive-or and bit scramble function using the random data in the code page as the scramble and unscramble template;

wherein said E-cipher and said E-decipher are devised small in size in compare to the data to be sent by said sender;

wherein said E-cipher and said E-decipher are arbitrarily selected, applied and changed from time to time; and

wherein said E-cipher and said E-decipher destroy themselves after arbitrary multiple uses.

2. A method encrypting a set of data from a sender to a receiver and decrypting said set of data received from said sender, comprising:

said sender uses an encrypting/decrypting device to encrypt a symmetric key (S-key) by a public key (PKI) cipher with a public key and send said encrypted S-key to said receiver;

said receiver uses a private key to decrypt said encrypted S-key to obtain said S-key;

said receiver uses said S-key to encrypt a receiver-selected-cipher (E-cipher) and send said encrypted E-cipher to said sender;

said sender uses said S-key to decrypt said encrypted E-cipher to obtain said E-cipher;

said receiver uses a receiver-selected-decipher (E-decipher) to decrypt data sent from said sender;

said sender or said receiver applies said E-cipher or said E-decipher, respectively, to carry out a session of encrypted data transmission;

said sender or said receiver applies said E-cipher

or said E-decipher, respectively, to carry out the session of encrypted data transmission further comprising a step of using a random data in a code page as a scramble and unscramble template,

wherein said E-cipher and said E-decipher include only exclusive-or and bit scramble function using the random data in the code page as the scramble and unscramble template;

wherein said E-cipher and said E-decipher are devised small in size in compare to the data to be sent by said sender;

wherein said E-cipher and said E-decipher are arbitrarily selected, applied and changed from time to time; and

wherein said E-cipher and said E-decipher destroy themselves after arbitrary multiple uses.

3. A method encrypting a set of data from a sender to a receiver and decrypting said set of data received from said sender, comprising:

said receiver uses an encrypting/decrypting device to encrypt a receiver-selected-cipher (E-cipher) by a public key (PKI) cipher with a public key and send said encrypted E-cipher to said sender;

said sender uses a private key to decrypt said encrypted E-cipher to obtain said E-cipher;

said receiver uses a receiver-selected-decipher (E-decipher) to decrypt data sent from said sender;

said sender or said receiver applies said E-cipher or said E-decipher, respectively, to carry out a session of encrypted data transmission;

said sender or said receiver applies said E-cipher

or said E-decipher, respectively, to carry out the session of encrypted data transmission further comprising a step of using a random data in a code page as a scramble and unscramble template,

wherein said E-cipher and said E-decipher include only exclusive-or and bit scramble function using the random data in the code page as the scramble and unscramble template;

wherein said E-cipher and said E-decipher are devised small in size in compare to the data to be sent by said sender;

wherein said E-cipher and said E-decipher are arbitrarily selected, applied and changed from time to time; and

wherein said E-cipher and said E-decipher destroy themselves after arbitrary multiple uses.
