METHOD AND SYSTEM FOR PROVIDING SERVICE ENCRYPTION AND DECRYPTION USING VERNAM CIPHER

摘要

The present invention relates to an encryption key generation service, and more particularly, to an encryption key generation service in which a data size is the same as that of data to be transmitted so as to apply a One Time Pads (OTP) or a Vernam Cipher algorithm Generates a first encryption key using an initial value generated under a predetermined time information basis in a plurality of devices based on the same hardware RNG (Random Number Generator) to generate an encryption key of the first encryption key, Based on a hardware-based RNG (cryptographic key generation) problem, which is a constraint of the OTP or Bark cipher technique, which is considered to be the most secure encryption algorithm by dynamically generating at least one encryption key successively following the first encryption key from the first encryption key Random Number Generator). In addition, the same random number is generated between hardware-based RNGs generated in the same manner, and a random number generated at the time of analyzing the RNG is changed, so as to provide a technology capable of secure encryption communication.
