第3题：

2 An important part of management is understanding the style. of leadership.

Required:

(a) Explain what Blake and Mouton’s Managerial Grid measures. (5 marks)


正确答案：
2 Overview:
The accountant is frequently the manager or group leader. An understanding of leadership theory and practice is therefore an
important part of an accountant’s training.
Part (a):
Robert Blake and Jane Mouton in their Ohio State Leadership Studies, observed two basic leadership dimensions that were
apparent from their studies; concern for the task and concern for people.
They recognised that it was possible for concern for the task to be independent of concern for people. It was therefore possible for
a leader to be strong on one and weak on the other, strong on both, weak on both or any variation in between.
They devised a series of questions, the answers to which enabled them to plot these two basic leadership dimensions. These two
dimensions were placed as the axes on a grid structure now known as the Managerial Grid. A person who scores 7 on ‘concern
for production’ (the x axis) and 5 on ‘concern for people’ (the y axis) is known as a 7,5 leader.

第5题：

Which statement is true regarding a session key in the Diffie-Hellman key-exchange process?（）

  • A、A session key value is exchanged across the network.
  • B、A session key never passes across the network.
  • C、A session key is used as the key for asymmetric data encryption.
  • D、A session key is used as the key for symmetric data encryption.

正确答案:B

第6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。

第7题：

Where parties do not have a shared secret and large quantities of sensitive information must be passed, the most efficient means of transferring information is to use Hybrid Encryption Methods. What does this mean?双方没有共享的密钥以及大量的敏感信息需要传输，最有效的用于信息传输的的方式是使用混合传输信息加密算法。这是什么意思？（）

  • A、Use of software encryption assisted by a hardware encryption accelerator.使用由硬件加密加速器协助的软件加密
  • B、Use of the recipient’s public key for encryption and decryption based on the recipient’s private key.使用接受方的公钥进行加密以及使用接受者的私钥既你想那个解密
  • C、Use of public key encryption to secure a secret key，and message encryption using the secret key.使用公钥加密来加密秘密会话密钥，并且使用秘密会话密钥来加密信息
  • D、Use of elliptic curve encryption.使用椭圆曲线加密

正确答案:C

正确答案:C

第10题：

What is one reason that WPA encryption is preferred over WEP?（）

  • A、A WPA key is longer and requires more special characters than the WEP key.
  • B、The access point and the client are manually configured with different WPA key values.
  • C、WPA key values remain the same until the client configuration is changed.
  • D、The values of WPA keys can change dynamically while the system is used.

正确答案:D
