SYMMETRICAL KEY ENCRYPTION SYSTEMS AND METHOD BASED ON HASH VALUE IN SMART DEVICE

摘要

The present invention relates to a symmetrical key encryption system and a method based on a hash value in a smart device and, more specifically, to a symmetrical key encryption system and a method based on a hash value in a smart device using unique identification information on the smart device as an encrypting and decrypting key of a symmetrical key method; searching and using the encrypting key to encrypt; generating a decryption key using the unique identification information on the smart device to decrypt.The system and method have a strong encryption advantage of the symmetrical key method and provide the key managing convenience of an asymmetrical key method.;COPYRIGHT KIPO 2014;[Reference numerals] (100) Encryption means; (101) Public hash key search unit; (102) Encoding unit; (200) Decoding means; (201) Hash key generator; (202) Hash key registering unit; (203) Decoding unit; (204) Public hash key validity determining unit; (300) Hash key public means; (301) Hash key management unit; (302) Hash key public unit; (AA,BB,CC) Wired/wireless Internet
