H.2 Organization Octet
33.2203GPPGeneric Authentication Architecture (GAA)Generic Bootstrapping Architecture (GBA)TS
The organization octet denotes the organization specifying the particular protocol. Each organization intending to specify a Ua security protocol identifier shall apply to 3GPP to receive an organization octet value, which shall be registered within this Annex. Following is a list of registered organization octets:
"0x00" as first octet is the default value for protocols not specified otherwise. When octet "0x00" is used as first octet, only Ua security protocol identifier ( 0x00,0x00,0x00,0x00,0x00 ) shall be used.
NOTE 1: All protocols having this Ua security protocol identifier cannot be separated from each other.
"0x01" .. "0xFE" as the first octet denote organizations specifying Ua security protocol identifiers.
"0xFF" as the first octet denotes the private range of Ua security protocol identifiers.
NOTE 2: identifiers with "0xFF" as first octet may be used for defining local/experimental protocols without need for registration. When using such an identifier, however, it may happen that a security breach in one security protocol over Ua can be exploited by an attacker to mount successful attacks on a different security protocol over Ua.
The following values for organizations are assigned:
"0x01" 3GPP
NOTE 3: All protocols having the organization octet "0x01" are specified in annex H.3.
"0x02" 3GPP2
"0x03" Open Mobile Alliance
"0x04" GSMA
