공개 메소드들

메소드	설명
Create ( PolicyAce singlePolicyChain ) : void	Create a simple policy chain (no ORs).
CreateNormalizedPolicy ( PolicyAce policy ) : void	A "normalized" policy is one transformed into disjunctive normal form in which a collection of policy "AND chains" is combined with PolicyOR before submission to the TPM. Callers must provide an-array-of-arrays of TpmPolicyACEs. The arrays may NOT contain PolicyOr (these will be added automatically), but each array MUST be terminated with a unique string identifier encoded in a TpmPolicyChainId.
Deserialize ( PolicySerializationFormat format, Stream sourceStream ) : void	Load a policy from a stream (MemoryStream, FileStream) in the specified format
DeserializeFromFile ( PolicySerializationFormat fmt, string fileName ) : void
DeserializeFromString ( PolicySerializationFormat fmt, string stream ) : void
GetDataStructureToSign ( int expirationTime, byte nonceTpm, byte cpHash, byte policyRef ) : byte[]	This is a formatting helper to help callbacks create a properly formed hash to sign.
GetPolicyDigest ( ) : TpmHash
GetPolicyRoot ( ) : PolicyAce
InsertPolicyRoot ( PolicyAce newRoot ) : PolicyTree
PolicyTree ( TpmAlgId hashAlgorithm ) : System
ResetPolicyDigest ( ) : void
Serialize ( string policyIdentifier, PolicySerializationFormat format, Stream targetStream ) : void	Create a serialization of the current policy object in a stream (e.g. MemoryStream or FileStream)
SerializeToFile ( string policyIdentifier, PolicySerializationFormat fmt, string fileName ) : void
SerializeToString ( string policyIdentifier, PolicySerializationFormat fmt ) : string
Set ( PolicyAce leaf ) : void	Sets the current policy tree to a policy branch represented by its leaf ACE. A policy branch can be constructed by means of the following expressions: new TpmAce1().And(new TpmAce2()).And(new TpmAce3()); or new TpmAce1().AddNextAce(new TpmAce2()).AddNextAce(new TpmAce3());
SetNvCallback ( PolicyNVDelegate policyNvCallback ) : void

SetPolicyRoot ( PolicyAce root ) : PolicyAce
SetPolicySecretCallback ( PolicySecretDelegate policySecretCallback ) : void
SetSignerCallback ( SignDelegate signer ) : void

CheckPolicy ( string branchIdToFind, PolicyAce &matchingAce ) : void	Check to see if all branches have an ID and that the IDs are unique.
CheckPolicyIdInternal ( PolicyAce ace, string branchIdToFind, PolicyAce &matchingAce, string nodeIdToFind = "" ) : void
ExecutePolicyActionCallback ( TpmPolicyAction ace ) : void
ExecutePolicyNvCallback ( TpmPolicyNV ace, TpmHandle &authHandle, TpmHandle &nvHandle, SessionBase &authSession ) : void	Called from TpmPolicyNV.
ExecutePolicySecretCallback ( TpmPolicySecret ace, SessionBase &authorizingSession, TpmHandle &authorizedEntityHandle, bool &flushAuthEntity ) : void	Called from TpmPolicySecret.
ExecuteSignerCallback ( TpmPolicySigned ace, byte nonceTpm, TpmPublic &verificationKey ) : ISignatureUnion	This is called from TpmPolicySigned when an external caller must sign the session data.

메소드 상세

Create() 공개 메소드

Create a simple policy chain (no ORs).

public Create ( PolicyAce singlePolicyChain ) : void
singlePolicyChain	PolicyAce
리턴	void

CreateNormalizedPolicy() 공개 메소드

A "normalized" policy is one transformed into disjunctive normal form in which a collection of policy "AND chains" is combined with PolicyOR before submission to the TPM. Callers must provide an-array-of-arrays of TpmPolicyACEs. The arrays may NOT contain PolicyOr (these will be added automatically), but each array MUST be terminated with a unique string identifier encoded in a TpmPolicyChainId.

public CreateNormalizedPolicy ( PolicyAce policy ) : void
