Constructor & Destructor Documentation

◆ jmemblob() [1/3]

ProtocolPP::jmemblob::jmemblob	(	std::shared_ptr< jrand > &	rand,
		uint8_t *	bkek,
		uint32_t	bkek_size,
		uint8_t *	blobkey,
		uint32_t	blobkey_size
	)

Constructor for memory BLOB

Parameters

rand	- randomizer
bkek	- system level key used for offline key protection
bkek_size	- size of the bkek
blobkey	- BLOB key used for offline key protection
blobkey_size	- size of the blob key

◆ jmemblob() [2/3]

ProtocolPP::jmemblob::jmemblob	(	std::shared_ptr< jrand > &	rand,
		jmemblobsa &	security
	)

Constructor for memory BLOB security association

Parameters

rand	- randomizer
security	- BLOB security association

◆ jmemblob() [3/3]

ProtocolPP::jmemblob::jmemblob	(	std::shared_ptr< jrand > &	rand,
		std::shared_ptr< jmemblobsa > &	security
	)

Constructor for memory BLOB security association

Parameters

rand	- randomizer
security	- BLOB security association pointer

Member Function Documentation

◆ decap_packet()

void ProtocolPP::jmemblob::decap_packet	(	std::shared_ptr< jarray< uint8_t > > &	input,
		std::shared_ptr< jarray< uint8_t > > &	output
	)

virtual

Decapsulate the data as a Blob. Due to the nature of the Blob Key Encryption Key (BKEK) and how it's constructed, this function must supply the BKEK from the system. The BKEK bits are not accessible once the design is in silicon. Furthermore, Blob construction is typically specific to the device such that only that device can retrieve the Blob

Parameters

input	- Encapsulated Blob data
output	- correctly sized pointer to hold plaintext Blob data

Implements ProtocolPP::jprotocol.

◆ encap_packet()

void ProtocolPP::jmemblob::encap_packet	(	std::shared_ptr< jarray< uint8_t > > &	input,
		std::shared_ptr< jarray< uint8_t > > &	output
	)

virtual

Encapsulate the data as a Blob. Due to the nature of the Blob Key Encryption Key (BKEK) and how it's constructed, this function must supply the BKEK from the system. The BKEK bits are not accessible once the design is in silicon. Furthermore, Blob construction is typically specific to the device such that only that device can create and retrieve the Blob

Parameters

input	- Data to enacapsulate as the Blob
output	- Correctly sized pointer to hold encapsulated Blob

Implements ProtocolPP::jprotocol.

◆ get_field()

uint64_t ProtocolPP::jmemblob::get_field	(	field_t	field,
		jarray< uint8_t > &	hdr
	)

virtual

Not used in this protocol

Returns: 0

Implements ProtocolPP::jprotocol.

◆ get_hdr()

jarray< uint8_t > ProtocolPP::jmemblob::get_hdr ( )

virtual

Not used in this protocol

Returns: empty array

Implements ProtocolPP::jprotocol.

◆ get_security()

void ProtocolPP::jmemblob::get_security ( std::shared_ptr< jmemblobsa > & sec )

get_security

Parameters

sec	- Shared pointer to hold the security association

◆ set_field()

void ProtocolPP::jmemblob::set_field	(	field_t	field,
		uint64_t	value
	)

virtual

Not used in this protocol

Parameters

field	- field to update
value	- new value for the field

Implements ProtocolPP::jprotocol.

◆ set_hdr()

void ProtocolPP::jmemblob::set_hdr ( jarray< uint8_t > & hdr )

virtual

Not used in this protocol

Parameters

hdr	- header of the packet

Implements ProtocolPP::jprotocol.

◆ to_json()

void ProtocolPP::jmemblob::to_json	(	std::ofstream &	myjson,
		direction_t	direction,
		std::string &	indent
	)

virtual

Prints the protocol object in JSON

Parameters

myjson	- JSON object to print to
direction	- randomzation
indent	- indentation for JSON output

Implements ProtocolPP::jprotocol.

◆ to_xml()

void ProtocolPP::jmemblob::to_xml	(	tinyxml2::XMLPrinter &	myxml,
		direction_t	direction
	)

virtual

Prints the protocol object in XML

Parameters

myxml	- XMLPrinter object to print to
direction	- randomzation

Implements ProtocolPP::jprotocol.
