混合加密的宋词载体文本信息隐藏技术
Text Information Hiding Technique by Carrier of Song Poetry Based on Hybrid Encryption
摘要
Abstract
To further improve the security of information hiding system,we put forward a secure text information hiding scheme with Song Poetry based on mixed encryption in this paper. It encrypts the original information with the advanced encryption standard ( AES) ,and then uses elliptic curve cryptography ( ECC) to encrypt AES keys. Finally,it uses the Song-Steg to hide the encrypted cipher text and keys,and then generates some Song Poetries with a randomly selected or a specified Ci-Pai template. The average encryption and decryption time for 100 Chinese characters are 79. 6 ms and 33. 3 ms,and the embedding rate is up to 28. 13％. Compared with the existing scheme,it has more advantage in the embedding rate and the concealment. Thus the encryption operation is equivalent to the original information itself joined the random noise. Even if the information hiding system be cracked,attackers are hard to decrypt reduction. For generated steganography Song Poetry is identical with the original one,it is difficult for an attacker to steganalyses and get the embedded information extremely,and the se-curity has been substantially improved.关键词
