All of these merits have made it the best public - key cryptosystem that is suitable for current use in future 因此,椭圆曲线密码系统被认为是最有希望成为下一代通用的公钥密码系统。
Rsa cryptosystem , a public - key cryptosystem being used widely today , seems to have difficulty in meeting the users ’ need of higher security 现在广泛使用rsa公钥密码系统已很难满足未来人们对信息高安全性的需求。
Public key cryptosystems , such as rsa , and symmetric algorithms , such as des - the most common ways to address the data confidentiality problem 公钥密码系统,譬如rsa ,对称演算法,譬如des这是解决资料机密性问题的最常用方法。
As we have explained , public key cryptosystems are usually used to encrypt a message using the receiver s public key , which the receiver then decrypts with the corresponding private key 正如我们所解释的,公钥密码系统经常使用接收方公钥来加密讯息,然后接收方使用相应的专用密钥解密。
In addition to its high security , ecc also has many other merits over other public - key cryptosystems such as less computation overheads , shorter key size , considerable bandwidth savings , and so on 与其他公钥密码系统相比,椭圆曲线密码除了安全性高外,还具有计算负载小,密码尺寸短,占用带宽少等优点。
