/* 5.2 TPM_VERSION_BYTE rev 87

   Allocating a byte for the version information is wasteful of space. The current allocation does
   not provide sufficient resolution to indicate completely the version of the TPM. To allow for
   backwards compatibility the size of the structure does not change from 1.1.
   
   To enable minor version, or revision, numbers with 2-digit resolution, the byte representing a
   version splits into two BDC encoded nibbles. The ordering of the low and high order provides
   backwards compatibility with existing numbering.
   
   An example of an implementation of this is; a version of 1.23 would have the value 2 in bit
   positions 3-0 and the value 3 in bit positions 7-4.

   TPM_VERSION_BYTE is a byte. The byte is broken up according to the following rule

   7-4 leastSigVer Least significant nibble of the minor version. MUST be values within the range of
        0000-1001
   3-0 mostSigVer Most significant nibble of the minor version. MUST be values within the range of

   The digest value reports the result of a hash operation.

   In version 1 the hash algorithm is SHA-1 with a resulting hash result being 20 bytes or 160 bits.

   It is understood that algorithm agility is lost due to fixing the hash at 20 bytes and on
   SHA-1. The reason for fixing is due to the internal use of the digest. It is the authorization
   values, it provides the secrets for the HMAC and the size of 20 bytes determines the values that
   can be stored and encrypted. For this reason, the size is fixed and any changes to this value
   require a new version of the specification.

   The digestSize parameter MUST indicate the block size of the algorithm and MUST be 20 or greater.

   For all TPM v1 hash operations, the hash algorithm MUST be SHA-1 and the digestSize parameter is
   therefore equal to 20.

/* 9.5 TPM_BOUND_DATA rev 87 

   This structure is defined because it is used by a TPM_UnBind command in a consistency check.

   The intent of TCG is to promote "best practice" heuristics for the use of keys: a signing key
   shouldn't be used for storage, and so on. These heuristics are used because of the potential
   threats that arise when the same key is used in different ways. The heuristics minimize the
   number of ways in which a given key can be used.

   One such heuristic is that a key of type TPM_KEY_BIND, and no other type of key, should always be
   used to create the blob that is unwrapped by TPM_UnBind. Binding is not a TPM function, so the
   only choice is to perform a check for the correct payload type when a blob is unwrapped by a key
   of type TPM_KEY_BIND. This requires the blob to have internal structure.

   Even though payloadData has variable size, TPM_BOUND_DATA deliberately does not include the size
   of payloadData. This is to maximise the size of payloadData that can be encrypted when
   TPM_BOUND_DATA is encrypted in a single block. When using TPM-UnBind to obtain payloadData, the
   size of payloadData is deduced as a natural result of the (RSA) decryption process.

   1. This structure MUST be used for creating data when (wrapping with a key of type TPM_KEY_BIND)
   or (wrapping using the encryption algorithm TPM_ES_RSAESOAEP_SHA1_MGF1). If it is not, the
   TPM_UnBind command will fail.

   The minimum granularity for delegation is at the ordinal level. It is not possible to delegate an

/* 15.1 TPM_CURRENT_TICKS rev 110

   This structure holds the current number of time ticks in the TPM. The value is the number of time
   ticks from the start of the current session. Session start is a variable function that is
   platform dependent. Some platforms may have batteries or other power sources and keep the TPM
   clock session across TPM initialization sessions.
   
   The <tickRate> element of the TPM_CURRENT_TICKS structure provides the number of microseconds per
   tick.  The platform manufacturer must satisfy input clock requirements set by the TPM vendor to
   ensure the accuracy of the tickRate.
   
   No external entity may ever set the current number of time ticks held in TPM_CURRENT_TICKS. This
   value is always reset to 0 when a new clock session starts and increments under control of the
   TPM.
   
   Maintaining the relationship between the number of ticks counted by the TPM and some real world
   clock is a task for external software.

   This is the header for the wrapped context. The blob contains all information necessary to reload
   the context back into the TPM.
   
   The additional data is used by the TPM manufacturer to save information that will assist in the
   reloading of the context. This area must not contain any shielded data. For instance, the field
   could contain some size information that allows the TPM more efficient loads of the context. The
   additional area could not contain one of the primes for a RSA key.
   
   To ensure integrity of the blob when using symmetric encryption the TPM vendor could use some
   valid cipher chaining mechanism. To ensure the integrity without depending on correct
   implementation, the TPM_CONTEXT_BLOB structure uses a HMAC of the entire structure using tpmProof
   as the secret value.

   Since both additionalData and sensitiveData are informative, any or all of additionalData 
   could be moved to sensitiveData.
