var enhancedsecuritycontrolBME *ManagedEntityDefinition

// EnhancedSecurityControl (class ID #332)
//	This ME contains the capabilities, parameters and controls of enhanced GPON security features
//	when they are negotiated via the OMCI (Note). The attributes in this ME are intended to be used
//	to implement a symmetric-key-based three step authentication process as described in the
//	supplemental information section in the following.
//
//	NOTE - If an ITU-T G.987 system uses 802.1X authentication as defined in [ITU-T G.987.3], the
//	only applicable attribute of this ME is the broadcast key table.
//
//	Relationships
//		One instance of this ME is associated with the ONU ME.
//
//	Attributes
//		Managed Entity Id
//			Managed entity ID: This attribute uniquely identifies each instance of this ME. There is only
//			one instance, number 0. (R) (mandatory) (2 bytes)
//
//		Olt Crypto Capabilities
//			(W) (mandatory) (16 bytes)
//
//		Olt Random Challenge Table
//			NOTE - It is assumed that the length of OLT_challenge is always an integer multiple of 16-bytes.
//
//		Olt Challenge Status
//			The ONU initializes this attribute to the value false. (R, W) (mandatory) (1-byte)
//
//		Onu Selected Crypto Capabilities
//			ONU selected crypto capabilities: This attribute specifies the cryptographic capability selected
//			by the ONU in authentication step 2. Its value specifies one of the bit positions that has the
//			value 1 in the OLT crypto capabilities attribute. (R) (mandatory) (1 byte)
//
//		Onu Random Challenge Table
//			ONU random challenge table: This attribute specifies the random challenge ONU_challenge issued
//			by the ONU during authentication step 2. It is structured as a table, with each entry being
//			16-bytes of content. ONU_challenge is the concatenation of all 16-byte content fields in the
//			table. Once the OLT triggers a response to be generated using the OLT challenge status
//			attribute, the ONU generates the response and writes the table (in a single operation). The AVC
//			generated by this attribute signals to the OLT that the challenge is ready, so that the OLT can
//			commence a get/get-next sequence to obtain the table's contents. (R) (mandatory) (16 * P-bytes)
//
//		Onu Authentication Result Table
//			Once the OLT triggers a response to be generated using the OLT challenge status attribute, the
//			ONU generates ONU_result and writes the table (in a single operation). The AVC generated by this
//			attribute signals to the OLT that the response is ready, so that the OLT can commence a get/get-
//			next sequence to obtain the table's contents. (R) (mandatory) (16 * Q-bytes)
//
//		Olt Authentication Result Table
//			This attribute is structured as a table, with each entry being 17 bytes. The first byte is the
//			table row number, starting at 1; the remaining 16 bytes are content. OLT_result is the
//			concatenation of all 16-byte content fields. The OLT writes all entries into the table, and then
//			triggers the ONU's processing of the table using the OLT result status attribute. The number of
//			rows R is implicit in the choice of hash algorithm. The OLT can clear the table with a set
//			operation to row 0. (W) (mandatory) (17 * R-bytes)
//
//		Olt Result Status
//			(R, W) (mandatory) (1 byte)
//
//		Onu Authentication Status
//			(R) (mandatory) (1 byte)
//
//		Master Session Key Name
//			Upon the invalidation of a master session key (e.g., due to an ONU reset or deactivation, or due
//			to an ONU-local decision that the master session key has expired), the ONU sets the master
//			session key name to all zeros. (R) (mandatory) (16 bytes)
//
//		Broadcast Key Table
//			(R, W) (optional) (18N bytes)
//
//		Effective Key Length
//			Effective key length: This attribute specifies the maximum effective length, in bits, of keys
//			generated by the ONU. (R) (optional) (2 bytes)
//
