【摘要】 随着越来越多的使用电子邮件,它所传送的内容也越来越广泛.因此保证其中敏感数据及重要内容的安全成了当务之急.但使用传统的PKI方法太过复杂,阻碍了具体的实施计划.根据新兴的公钥密码算法IBE(基于身份的加密)的特点,通过使用IBE来代替传统的PKI,并结合数字签名提出了一种新型的保证电子邮件安全的方案.通过对该方案的理论评估,可以看出该方案能够实现电子邮件的安全传送,同时该方案具有成本低、易于实现和适用范围广的特点.更多还原

【Abstract】 As E-mail is being used more and more widely,the contents it carries are more and more various.It is essential to ensure the security of the important and sensitive data.The complexity of traditional PKI way impacts its use in practice.By using the combination of the rising Public-Key Cryptographic Algorithms IBE instead of PKI and digital signature,this paper presents a new solution to ensure the security of E-mails.Through theory evaluation,it can be seen that this solution can achieve the secure delivery of E-mails.And it has the characteristic of low cost,easy implementation,wide use.更多还原
