解密时间(建设机器每秒尝试255个密钥) 非对称算法 常见的非对称加密算法如下: RSA:由 RSA 公司发明,是一个支持变长密钥的公共密钥算法,需要加密的文件块的长度也是可变的; DSA(Digital Signature Algorithm):数字签名算法,是一种标准的 DSS(数字签名标准); ECC(Elliptic Curves Cryptography):椭圆曲线密码编码学。

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 ...
