参考解析
解析：证书是一种数字文档，用于表明把一个公钥绑定到一个人或其他实体。用它可以验证一个给定的公钥确实属于某一个人。证书可以防止某些人使用假冒的密钥去冒充别人。最简单的证书包含一个公钥和一个名字。通常使用的证书也包含超时日期、发行证书的CA的名字、一个序列号，以及其他信息。最重要的是，它包含了证书发行者的数字签名。最广泛接受的证书格式是X.509，这样的证书可以被任何服从X.509标准的应用读或写。

Public Key Infrastructure(PKI) service providers offer organizations fully integrated PKI-managed services designed to secure Intranet, Extranet, Virtual Private Network(VPN), and e-commerce applications. PKI solutions can enable a number of security services, including strong authentication and non-repudiation of transactions.eToken enables the users of PKI systems to generate and store(101)and digital certificates inside the token, creating a secure environment and allowing full portability and maximum ease of use. eToken Pro can also perform. sensitive on-chip(102)operations, ensuring that users' keys axe never exposed to the PC environment, eToken eliminates the need to store(103)and keys on a hard disk or browser file, or to transmit them across the Internet/Extranet; assuring peace-of-mind and confidence during online communications.A digital signature is created using the private key of an individual to ensure the Validity of his request. This technology can be used to guarantee(104)of various transactions. The strength of either the authentication level or the digital signature relies on the level of protection offered to the private key. eToken Pro offers the maximum level of security, since it enables the use of the private key for signing and authenticating inside the eToken.The most secure use of authentication involves enclosing at least one certificate with every signed message. The message(105)verifies the certificate using the CA's public key. If the sender's public key is legitimate, the recipient verifies the message's signature. Digital signatures created with a private key are verified with the digital certificate containing the public key.A．private keysB．public keysC．authentication codesD．message digests

Symmetric, or private-key, encryption is based on a secret key that is shared by both communcating parties. The （ ） party uses the secret key as part of the mathematical operation to encrypt （ ） text to cipher text. The receiving party uses the same secret key to decrypt the cipher text to plain text. Asymmetric, or public-key, encryption uses two different keys for each user: one is a （ ） key known only to this one user; the other is a corresponding public key, which is accessible to anyone. The private and public keys are mathematically related by the encryption algorithm. One key ia used for encyption and the other for decryption, depending on the nature of the communication service being implemented. In addition, public key encryption technoligies allow digital （ ） to be placed on messages. A digital signature uses the senders private key to encrypt some portion of the message.
