MD5(Message-Digest Algorithm 5,信息-摘要算法5):是一种信息摘要算法、哈希算法,不可逆; DES(Data Encryption Standard,数据加密标准):是一种对称加密算法,加解密需要同一个密钥; AES(Advanced Encryption Standard,高级加密标准), 也是一种对称加密算法,是DES的升级版。 目前来说,DES比较脆弱,所以推荐用AES。 核...
Here, We have successfully implemented the proposed methodology using DES (Data Encryption Standard)algorithm. The concept is enhanced by the transformation of meaningless to meaningful shares and the security is enhanced by encrypting the shares of the secret image by using DES. The tool that we ...
