| 摘 要： | 提出一种基于ECC签密的消息交换方案.方案中对交换的消息进行数字签名和加密处理,其认证和保密的基础都是建立在ECC之上,利用有限域上椭圆曲线的点群中的离散对数问题难解性来增强方案的安全性.通信的各方产生自己的私钥和公钥对,用户的证书由CA(Certification Authority)签发后交给用户保存,交换的消息和其签名等信息采用压缩加密传输,避免了消息在传输的过程中被第三者窃取或篡改,保证了数据的机密性、完整性和不可否认性.

| Abstract: | A scheme of message interchange based on ECC is proposed.The digital signature and symmetric key exchange in the scheme are both established based on ECC.The computational intractability of the elliptic curve discrete logarithm problem (ECDLP) over a finite field enhances the security of the scheme.Each end user in a network generates its own private key and public key.Users' certificates are signed by CA and then respectively sent to each user to keep.The message and its digital signature are encrypted to ... |
