The security services that public key cryptography enable are based on the fact that a message encrypted using the public key can only be decrypted by the corresponding private key, and vice versa.

公钥密码启用的安全性服务是基于这样的消息解密机制，即共有密钥只能通过相应的私有密钥才能解密，反之亦然。

This approach involving private and public key pairs is also known as public key cryptography.

这种涉及到私钥和公钥对的方式也被称作公钥密码术。

The transmitted data is encrypted using public key (asymmetric) cryptography so that only the holder of the corresponding private key can decrypt the data.

传递的数据使用公钥(非对称)加密算法加密，所以只有对应私钥的持有者才能解密数据。

It would use public key cryptography to generate and store thousands of public and private key pairs, one for every app or gadget the user needs to unlock.
