Class EphemeralIdRegistration
Write-only registration parameters for beacons using Eddystone-EID format. Two ways of securely registering an Eddystone-EID beacon with the service are supported:
- Perform an ECDH key exchange via this API, including a previous call to
GET /v1beta1/eidparams
. In this case the fieldsbeacon_ecdh_public_key
andservice_ecdh_public_key
should be populated andbeacon_identity_key
should not be populated. This method ensures that only the two parties in the ECDH key exchange can compute the identity key, which becomes a secret between them. 2. Derive or obtain the beacon's identity key via other secure means (perhaps an ECDH key exchange between the beacon and a mobile device or any other secure method), and then submit the resulting identity key to the service. In this casebeacon_identity_key
field should be populated, and neither ofbeacon_ecdh_public_key
norservice_ecdh_public_key
fields should be. The security of this method depends on how securely the parties involved (in particular the bluetooth client) handle the identity key, and obviously on how securely the identity key was generated.
See the Eddystone specification at GitHub.

Syntax
public class EphemeralIdRegistration : IDirectResponseSchema
Properties
BeaconEcdhPublicKey
The beacon's public key used for the Elliptic curve Diffie-Hellman key exchange. When this field is
populated, service_ecdh_public_key
must also be populated, and beacon_identity_key
must not
be.
Declaration
[JsonProperty("beaconEcdhPublicKey")]
public virtual string BeaconEcdhPublicKey { get; set; }
Property Value
Type | Description |
---|---|
System.String |
BeaconIdentityKey
The private key of the beacon. If this field is populated, beacon_ecdh_public_key
and
service_ecdh_public_key
must not be populated.
Declaration
[JsonProperty("beaconIdentityKey")]
public virtual string BeaconIdentityKey { get; set; }
Property Value
Type | Description |
---|---|
System.String |
ETag
The ETag of the item.
Declaration
public virtual string ETag { get; set; }
Property Value
Type | Description |
---|---|
System.String |
InitialClockValue
The initial clock value of the beacon. The beacon's clock must have begun counting at this value immediately prior to transmitting this value to the resolving service. Significant delay in transmitting this value to the service risks registration or resolution failures. If a value is not provided, the default is zero.
Declaration
[JsonProperty("initialClockValue")]
public virtual ulong? InitialClockValue { get; set; }
Property Value
Type | Description |
---|---|
System.Nullable<System.UInt64> |
InitialEid
An initial ephemeral ID calculated using the clock value submitted as initial_clock_value
, and
the secret key generated by the Diffie-Hellman key exchange using service_ecdh_public_key
and
service_ecdh_public_key
. This initial EID value will be used by the service to confirm that the key
exchange process was successful.
Declaration
[JsonProperty("initialEid")]
public virtual string InitialEid { get; set; }
Property Value
Type | Description |
---|---|
System.String |
RotationPeriodExponent
Indicates the nominal period between each rotation of the beacon's ephemeral ID. "Nominal" because the beacon should randomize the actual interval. See the spec at github for details. This value corresponds to a power-of-two scaler on the beacon's clock: when the scaler value is K, the beacon will begin broadcasting a new ephemeral ID on average every 2^K seconds.
Declaration
[JsonProperty("rotationPeriodExponent")]
public virtual long? RotationPeriodExponent { get; set; }
Property Value
Type | Description |
---|---|
System.Nullable<System.Int64> |
ServiceEcdhPublicKey
The service's public key used for the Elliptic curve Diffie-Hellman key exchange. When this field
is populated, beacon_ecdh_public_key
must also be populated, and beacon_identity_key
must not
be.
Declaration
[JsonProperty("serviceEcdhPublicKey")]
public virtual string ServiceEcdhPublicKey { get; set; }
Property Value
