Abstract
Various embodiments disclose a method including storing, by a first node in a wireless network, a first key in a first memory; storing, by the first node, a second key in a second memory; and in response to an outage event: securing, by the first node using the second key, a first message and sending, by the first node, the secured first message. The first key is for securing messages in a normal power mode. The second key is for securing messages in a low power mode. The second memory uses less power than the first memory.
Claims20
A method comprising:
- storing, by a first node in a wireless network, a first key in a first memory, the first key for securing messages in a normal power mode;
- storing, by the first node, a second key in a second memory, the second key for securing messages in a low power mode, the second memory using less power than the first memory;
- and
- in response to an outage event:
- securing, by the first node using the second key, a first message;
- and
- sending, by the first node, the secured first message.
One or more non-transitory computer-readable media storing program instructions that, when executed by one or more processors of a node device in a wireless network, cause the one or more processors to perform the steps of:
- in response to determining that the node device should shut down and before shutting down the node device:
- transitioning the node device to a low power mode;
- while the node device is in the low power mode:
- creating a status report;
- retrieving a first key that is stored in a first memory for securing messages in the low power mode, wherein a second key is stored in a key store for securing messages in a normal power mode, the first memory using less power than a second memory storing the key store;
- securing, using the first key, the status report;
- and
- transmitting the secured status report.
A networking device comprising:
- a transceiver;
- one or more processors;
- a first memory for storing keys for use in a normal power mode;
- a second memory for storing keys for use in a low power mode, the second memory consuming less power than the first memory;
- and
- one or more third memories storing instructions that when executed by the one or more processors cause the one or more processors to perform operations comprising:
- detecting, while an operating mode of the networking device is the normal power mode, a condition associated with an outage;
- and
- in response to detecting the condition:
- loading a first key from the second memory;
- securing, using the first key, an outage reporting message;
- and
- transmitting, using the transceiver, the secured outage reporting message.
