摘要: |
变电站综合自动化系统的网络结构目前已广泛采用以太网,以太网良好的开放性带来的网络安全问题已引起人们的极大关注。通过网络的遥控操作,其安全性就更为重要,为了加强遥控的安全性,除规范操作流程、增加防护墙外,将遥控报文进行加密也是一种有效办法。提出了一种基于令牌的遥控加密实现方法,该方法采用改进的RSA-1公开密钥算法,结合一次一密的加密思想,由测控装置产生令牌密文,操作员计算出令牌明文并回传测控装置以检测操作员的合法性。这样合法操作员能进行正常遥控,且能有效防止非法操作员的非法遥控。 |

Abstract: |
At present,network configuration of transformer substation automation abroad widely adopts Ethernet,security matter of Ethernet’s opening arose people′s keen attention. Security of remote control across network become even more important. To enhance the security of remote control, there is a good method on remoting control message encryption except for regulating operation flow and enhancing protective wall. This paper brings forward a sort of remote control realization based on token.It adopts ameliorative RSA-1 publicity secret key arithmetic and combines method of encrypting on every operations. The measurement-control device brings up token, the operator calculates encrypted database and feedback measurement-control device to detecting the legitimacy of operator. In this way, legal operator can process normal remote control, and can effectively avoid any illegal remote control of any illegal operator. |
