Class TPMS_CONTEXT

java.lang.Object

tss.TpmStructure

tss.tpm.TPMS_CONTEXT

All Implemented Interfaces:

TpmMarshaller

public class TPMS_CONTEXT
extends TpmStructure

This structure is used in TPM2_ContextLoad() and TPM2_ContextSave(). If the values of the TPMS_CONTEXT structure in TPM2_ContextLoad() are not the same as the values when the context was saved (TPM2_ContextSave()), then the TPM shall not load the context.

Field Summary

Fields

Modifier and Type	Field and Description
TPMS_CONTEXT_DATA	contextBlob the context data and integrity HMAC
TPM_HANDLE	hierarchy the hierarchy of the context
TPM_HANDLE	savedHandle a handle indicating if the context is a session, object, or sequence object See Table 212 Context Handle Values
long	sequence the sequence number of the context NOTE Transient object contexts and session contexts used different counters.

Field Detail

sequence

public long sequence

the sequence number of the context NOTE Transient object contexts and session contexts used different counters.

savedHandle

public TPM_HANDLE savedHandle

a handle indicating if the context is a session, object, or sequence object See Table 212 Context Handle Values

hierarchy

public TPM_HANDLE hierarchy

the hierarchy of the context

contextBlob

public TPMS_CONTEXT_DATA contextBlob

the context data and integrity HMAC

Constructor Detail

TPMS_CONTEXT

public TPMS_CONTEXT(long _sequence,
                    TPM_HANDLE _savedHandle,
                    TPM_HANDLE _hierarchy,
                    TPMS_CONTEXT_DATA _contextBlob)

This structure is used in TPM2_ContextLoad() and TPM2_ContextSave(). If the values of the TPMS_CONTEXT structure in TPM2_ContextLoad() are not the same as the values when the context was saved (TPM2_ContextSave()), then the TPM shall not load the context.

Parameters:

_sequence - the sequence number of the context NOTE Transient object contexts and session contexts used different counters.

_savedHandle - a handle indicating if the context is a session, object, or sequence object See Table 212 Context Handle Values

_hierarchy - the hierarchy of the context

_contextBlob - the context data and integrity HMAC

TPMS_CONTEXT

public TPMS_CONTEXT()

This structure is used in TPM2_ContextLoad() and TPM2_ContextSave(). If the values of the TPMS_CONTEXT structure in TPM2_ContextLoad() are not the same as the values when the context was saved (TPM2_ContextSave()), then the TPM shall not load the context.
