基于双表体制的RSA加密算法

摘要

RSA Encryption algorithm is a public key algorithm and also relatively perfect. Its security intensity is high and easily to use,so widely used. The choice of its safety depends on prime number. Because of choosing prime number difficulty and a lot of time overhead on power by computing .This paper presents a double table system of RSA encryption algorithm. Based on double table system of RSA encryption algorithm that uses before and after the nested encryption characters. This way can increased the complexity of the ciphertext,so on the choice of big prime number can decrease relatively large prime Number of digits,reduce the time of power by operation,to achieve the effect of rapid encryption . Combining with the integrated development environment of eclipse,the encryption tool uses the eclipse plug-in form to complete the encryption of web documents.%RSA加密算法是比较完善的公开的密钥算法，由于其安全强度高，使用方便，所以受到广泛的应用。其安全性依赖于大素数的选择，但大素数产生技术的限制和RSA幂乘运算的大时间开销，提出一种基于双表体制的RSA加密算法。基于双表体制的RSA加密算法是将前后字符嵌套加密，增加了密文的复杂程度，因此，在大素数的选择上可以相对减少大素数的位数，减少幂乘运算的时间，达到快速加密的效果。结合Eclipse集成开发环境，加密工具采用Eclipse插件形式完成对web文件的加密。
