您正在開發(fā)一個方法，以使用數據加密標準(DES) 算法對敏感數據進行加密。您的方法接受下列參數：
·名為message 的待加密的字節(jié)數組
·名為key 的加密密鑰
·名為iv 的初始化向量
您需要對數據加密。您還需要將加密數據寫入MemoryStream對象。
您應該使用哪個代碼段？
A.
DES des = new DESCryptoServiceProvider();
des.BlockSize = message.Length;
ICryptoTransform crypto = des.CreateEncryptor(key, iv);
MemoryStream cipherStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(cipherStream, crypto, CryptoStreamMode.Write);
cryptoStream.Write(message, 0, message.Length);
B.
DES des = new DESCryptoServiceProvider();
ICryptoTransform crypto = des.CreateDecryptor(key, iv);
MemoryStream cipherStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(cipherStream, crypto, CryptoStreamMode.Write);
cryptoStream.Write(message, 0, message.Length);
C.
DES des = new DESCryptoServiceProvider();
ICryptoTransform crypto = des.CreateEncryptor();
MemoryStream cipherStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(cipherStream, crypto, CryptoStreamMode.Write);
cryptoStream.Write(message, 0, message.Length);
D.
DES des = new DESCryptoServiceProvider();
ICryptoTransform crypto = des.CreateEncryptor(key, iv);
MemoryStream cipherStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(cipherStream, crypto, CryptoStreamMode.Write);
cryptoStream.Write(message, 0, message.Length);

ApplicationTrustCollection trusts;
trusts = ApplicationSecurityManager.UserApplicationTrusts;
foreach (ApplicationTrust trust in trusts)
{
Console.WriteLine(trust.ToString());
}
B.
ApplicationTrustCollection trusts;
trusts = ApplicationSecurityManager.UserApplicationTrusts;
foreach (ApplicationTrust trust in trusts)
{
Console.WriteLine(trust.ExtraInfo.ToString());

您創(chuàng)建一個通過使用最終用戶憑據運行的方法。您需要使用Microsoft Windows 組向用戶授權。您必須添加代碼段，該代碼段確定用戶是否在名為Clerk的本地組中。
您應該使用哪個代碼段？
A.
WindowsIdentity currentUser = WindowsIdentity.GetCurrent();
foreach (IdentityReference grp in currentUser.Groups) {
NTAccount grpAccount = ((NTAccount)grp.Translate(typeof(NTAccount)));
isAuthorized = grpAccount.Value.Equals(Environment.MachineName + @"\Clerk");
if(isAuthorized)
break;
}
B.
WindowsPrincipal currentUser = (WindowsPrincipal)Thread.CurrentPrincipal;
isAuthorized = currentUser.IsInRole("Clerk");
C.
GenericPrincipal currentUser = (GenericPrincipal) Thread.CurrentPrincipal;
isAuthorized = currentUser.IsInRole("Clerk");
D.
WindowsPrincipal currentUser = (WindowsPrincipal)Thread.CurrentPrincipal;
isAuthorized = currentUser.IsInRole(Environment.MachineName);
答案: B
15.
你正在開發(fā)一個通過最終用戶的憑證運行的應用程序。只有作為Administrator組成員的用戶才有權運行該應用程序。你編寫以下的安全代碼，以保護該應用程序中的敏感數據。
bool isAdmin=false;
WindowsBuiltInRole role=WindowsBuiltInRole.Administrator;
......
if(!isAdmin)
throw new Exception("User not permitted");
您需要向此安全代碼中添加一個代碼段，以確保該應用程序會在用戶不是Administrator的組的成員引發(fā)異常。
你應該使用哪個代碼段？
A.
WindowsPrincipal currentUser = (WindowsPrincipal)Thread.CurrentPrincipal;
IsAdmin= currentUser.IsInRole(role);
B.
WindowsIdentity currentUser = WindowsIdentity.GetCurrent();
foreach (IdentityReference grp in currentUser.Groups) {
NTAccount grpAccount=((NTAccount)grp.Translate(typeof(NTAccount)));
isAdmin=grp.Value.Equals(role);
if (isAdmin)
break;
}
C.
GenericPrincipal currentUser = (GenericPrincipal) Thread.CurrentPrincipal;
IsAdmin = currentUser.IsInRole(role.ToString());
D.
WindowsIdentity currentUser = (WindowsIdentity)Thread.CurrentPrincipal.Identity;
isAdmin=currentUser.Name.EndsWith("Administrator");
