| 摘 要： | 现代物流信息公用平台涉及到金融、政府、企业、商家和个人等各方面的利益,必须采取行之有效的安全服务措施,包括鉴别服务、访问控制服务、机密性服务、不可否认服务等。RSA算法是一种最重要的公钥密码算法,在业界应用20多年来一直未发现任何缺陷。RSA体制基于大数的因子分解,大数的因子分解在数学上是个难题,至今还没有有效的算法。因此,RSA算法的安全性很高,但算法工作量大。现代技术要求的安全位数是1024位(相当于308位十进制数),要保证20年的安全就要选择1280位长度,必须对RSA算法在现代物流信息公用平台中数字签名和身份认证进行严格的安全设计。 |
| 关 键 词： | 现代物流 信息公用平台 RSA算法 公钥密码 安全设计 |

| Abstract: | It is necessary that so me effective safety precautions would be adopted in logistics information publi c palt-form,such as user identification,access control,secret setting,noden y setting,etc.Because this paltform involves such ad-vantages as finance,gov ernment ,enterprise,commerce and individual.The factor analysis of a high num ber is a difficult problem in mathematic,no any effectual arithmetic has been g iven yet.Based on it,as the foremost arithmetic of open key code,RSA is very safe,and have been faultness for20years,but the workload is very huge too. The safety digit which the modern technonoly request is1024,it will be12 80if20years safety is requested,so a strict safety design by RSA is necessa ry to the digital sign and identity validate of logistics information public pal tform. |
| Keywords: | logistics information public platform RSA arithmetic open key code safety design |
