C# Класс Tpm2Lib.AuthSession

AuthSession encapsulates HMAC, policy, encryption/decryption, and audit sessions, i.e. all session types that are represented by a TPM handle created by means of TPM2_StartAuthSession command.

Открытые методы

Метод Описание
AuthSession ( ParametrizedHandle ph ) : System
AuthSession ( TpmHandle h ) : System

Constructs an object encapsulating a session opened in TPM. The Tpm2 object that was used to create the session tracks other information associated with it and uses it to compute session key and command/response HMAC.

NewNonceCaller ( ) : void
RunPolicy ( Tpm2 tpm, PolicyTree policyTree, string branchToEvaluate = null, bool allowErrors = false ) : TpmRc

Run a path on the policy tree. The path is identified by the leaf identifier string. A session is created and returned. If allowErrors is true then errors returned do not cause an exception (but are returned in the response code).

SetNonceTpm ( byte nonceTpm ) : void

Приватные методы

Метод Описание
AuthSession ( TpmSe sessionType, TpmHandle tpmKey, TpmHandle bindObject, byte nonceCaller, byte nonceTpm, SymDef symmetric, TpmAlgId authHash ) : System

Constructs a temporary object to hold parameters of a session. Intended only for internal use by the Tpm2 class.

CalcSessionKey ( ) : void

Calculate the session-key from the nonces and salt/bound values (if present)

CanEncrypt ( ) : bool

Checks whether the given session can be used for parameter encryption.

GetAuthHmac ( byte parmHash, Direction direction, byte nonceDec = null, byte nonceEnc = null ) : byte[]

Calculate and return the auth-hmac (or plaintext auth if it is a policy session with PlaintextAuth set) based on the current session parms.

Init ( AuthSession Params ) : void

Sets parameters associated with the session.

Initialized ( ) : bool

Returns true if the parameters associated with the session context in TPM have been set in this object.

ParmEncrypt ( byte parm, Direction inOrOut ) : byte[]
