Conversely,(71)encrypted with the private key can be decrypted only with the public key. Users can make their public keys(73)available or place them at a key distribution center or others to access. However, the private key must be(74)safe. In public-key systems there's no(75)to find a safe channel for communicating a shared secret key.A．binarytextB．hypertextC．plaintextD．supertext

3.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

  • 第3题：

    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 sender's private key to encrypt some portion of the message. When the message is received, the receiver uses the sender's （） key tp decipher the digital signature to verify the sender's identity.横线处应选（ ）。


    A. interpretation
    B.signatures
    C. encryption
    D.decryption

    答案：B
    解析：
    对称加密或私钥加密的基础是通信双方共享同一密钥。发送方使用一个密钥作为数学运算的一部分把明文加密成密文。接收方使用同一密钥把密文解密变成明文。在非对称或公钥加密方法中，每个用户使用两种不同的密钥:一个是只有这个用户知道的私钥;另一个是与其对应的任何人都知道的公钥。根据加密算法，私钥和公钥是数学上相关的。一个密钥用于加密，而另一个用于解密，依赖于实现的通信服务的特点而用法有所不同。此外，公钥加密技术也可以用于报文的数字签名。数字签名时使用发送方的私钥来加密一部分报文。当接收方收到报文时，就用发送方的公钥来解密数字签名，以便对发送方的标识进行验证。
