摘要:

针对传统RSA算法在移动OA系统中签名效率较低的问题,研究了基于混合密钥数字签名技术,开发了一个完整的移动OA系统。使用RSA算法进行数字签名前,先对文档用Hash函数生成数字摘要,然后进行数字签名。实验证明,混合密钥数字签名技术在保证安全的情况下,大幅提高了数字签名的效率。

关键词: RSA, 混合密钥, 数字签名, 移动OA

Abstract:

Aiming at the poor efficiency of the traditional RSA algorithm in the mobile OA system,a complete mobile OA system is developed based on the hybrid key digital signature technology.Before using the RSA algorithm,the digital signature is generated by the Hash function,and then the digital signature is performed.Experiments prove that the mixed key digital signature technology greatly improves the efficiency of the digital signature while maintaining the security.

Key words: RSA;hybrid key;digital signature;mobile OA
