隨著電網智能電表規范的大規模應用，國網標準的智能電表已成為電表行業推廣應用的主流,各地方電力和表廠希望只換不同密鑰的ESAM，電表不做任何改動就可以應用到不是電網管轄的電網領域。

一、整體(ti)框架設計

根據客(ke)戶需求，可以提(ti)供一(yi)級密(mi)鑰(yao)體系(xi)（縣(xian)市一(yi)級）和兩(liang)級密(mi)鑰(yao)體系(xi)（地區、縣(xian)市兩(liang)級）。

整體框架

二、密鑰系統

遵循用(yong)(yong)戶(hu)需(xu)求(qiu)及(ji)和(he)行(xing)(xing)業的(de)(de)(de)(de)相應(ying)規(gui)范。密鑰(yao)(yao)管理系(xi)統(tong)采(cai)用(yong)(yong)開放(fang)性設計，密鑰(yao)(yao)進行(xing)(xing)統(tong)一管理，保(bao)證(zheng)全(quan)(quan)系(xi)統(tong)IC卡(ka)技術(shu)和(he)產品的(de)(de)(de)(de)應(ying)用(yong)(yong)。加強(qiang)密鑰(yao)(yao)應(ying)用(yong)(yong)管理系(xi)統(tong)的(de)(de)(de)(de)通(tong)用(yong)(yong)性和(he)靈活性；在充分(fen)保(bao)證(zheng)密鑰(yao)(yao)系(xi)統(tong)安(an)全(quan)(quan)性的(de)(de)(de)(de)基礎上，支持(chi)應(ying)用(yong)(yong)密鑰(yao)(yao)的(de)(de)(de)(de)生成(cheng)、注入、導出、備份、恢復(fu)、更新、服務(wu)、銷毀(hui)等功能，實現(xian)密鑰(yao)(yao)的(de)(de)(de)(de)安(an)全(quan)(quan)管理。在整(zheng)個密鑰(yao)(yao)系(xi)統(tong)中，為保(bao)證(zheng)系(xi)統(tong)的(de)(de)(de)(de)安(an)全(quan)(quan)性，密鑰(yao)(yao)在密鑰(yao)(yao)系(xi)統(tong)中的(de)(de)(de)(de)傳(chuan)遞均(jun)要(yao)采(cai)用(yong)(yong)安(an)全(quan)(quan)報文(wen)的(de)(de)(de)(de)傳(chuan)輸方式，即(ji)密文(wen)+MAC的(de)(de)(de)(de)方式。密鑰(yao)(yao)的(de)(de)(de)(de)操(cao)作要(yao)受到嚴格的(de)(de)(de)(de)權限(xian)控制。同時必(bi)須要(yao)有(you)強(qiang)有(you)力的(de)(de)(de)(de)行(xing)(xing)政管理手段加以(yi)配合。

三、發卡系統

發卡系統主要是將應用密鑰由母卡導入到CPU卡中，各母卡中保存了相應的應用密鑰，也就是由PSAM卡母卡發行PSAM卡、密鑰下裝卡母卡發行密鑰下裝卡和密鑰恢復卡、現場參數設置卡母卡發行現場參數設置卡、數據回抄卡母卡發行數據回抄卡、加密機密鑰下裝卡母卡發行加密機模擬卡、用戶卡發卡母卡發行用戶卡。

發卡系統

PSAM卡完成本地售電(dian)(dian)(dian)的(de)(de)認證(zheng)功能；密鑰下裝卡完成電(dian)(dian)(dian)表(biao)上私(si)鑰的(de)(de)替(ti)(ti)換(huan)；密鑰恢復卡完成電(dian)(dian)(dian)表(biao)上公鑰的(de)(de)替(ti)(ti)換(huan)；現場參數(shu)設(she)置(zhi)卡完成私(si)鑰狀態下的(de)(de)一些參數(shu)修改；數(shu)據回抄(chao)卡完成對(dui)電(dian)(dian)(dian)表(biao)中ESAM里的(de)(de)數(shu)據回抄(chao)；加密機(ji)模(mo)擬卡完成遠程的(de)(de)一些功能操作；用戶(hu)卡用于(yu)用戶(hu)買電(dian)(dian)(dian)。

四、售電系統

針對(dui)國網(wang)自管(guan)戶(hu)新規范的(de)智能(neng)費控電(dian)(dian)(dian)(dian)能(neng)表(biao)，以(yi)及(ji)兼容現有預(yu)(yu)付費電(dian)(dian)(dian)(dian)能(neng)表(biao)售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)業務，預(yu)(yu)付費售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)系統主要功(gong)能(neng)應(ying)包括：讀寫卡售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)、電(dian)(dian)(dian)(dian)能(neng)表(biao)參數(shu)下發、購電(dian)(dian)(dian)(dian)信(xin)息下發、電(dian)(dian)(dian)(dian)量/電(dian)(dian)(dian)(dian)費抄收、階(jie)梯電(dian)(dian)(dian)(dian)價、銀(yin)電(dian)(dian)(dian)(dian)聯網(wang)、自助(zhu)售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)、與(yu)營銷系統中(zhong)的(de)客(ke)戶(hu)信(xin)息同步、結算、對(dui)賬(zhang)、統計分析(xi)等(deng)，具有與(yu)用電(dian)(dian)(dian)(dian)信(xin)息采集系統的(de)接口。全網(wang)統一的(de)預(yu)(yu)付費售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)系統應(ying)該(gai)可以(yi)實現異(yi)地售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)，但可以(yi)設置(zhi)一定的(de)權(quan)限(xian)開放或(huo)者關閉異(yi)地售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)的(de)功(gong)能(neng)。交易記錄、金(jin)額等(deng)賬(zhang)務信(xin)息集中(zhong)于(yu)電(dian)(dian)(dian)(dian)網(wang)售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)軟件，CPU卡、讀卡器、現金(jin)收取等(deng)營銷業務分布于(yu)各地市級售(shou)(shou)(shou)電(dian)(dian)(dian)(dian)終端。
