Abstract
An approach is provided for securely communicating in a wireless network. A cryptographic server generates a command to enable a secure mode of operation for a wireless device, wherein the wireless device can operate in a secure mode and an unsecure mode in support of two-way messaging. The cryptographic server sends the command to the wireless device to activate the secure mode of operation. The secure mode of operation provides transmission of an encrypted message by the wireless device over the wireless network.
Claims27
A method for communicating in a wireless network, the method comprising:
- generating a command to enable a secure mode of operation for a wireless device, wherein the wireless device is configured to operate in a secure mode and an unsecure mode in support of two-way messaging;
- transmitting the command to the wireless device to activate the secure mode of operation, wherein the secure mode of operation provides transmission of an encrypted message by the wireless device over the wireless network;
- establishing a shared secret key with the wireless device, wherein the shared secret key is utilized to output the encrypted message;
- obtaining signal strength of the wireless network with respect to the wireless device;
- and
- determining a random seed based on the signal strength, wherein the random seed is used to determine the shared secret key.
A network apparatus for supporting secure communication over a wireless network, the apparatus comprising:
- a processor configured to generate a command to enable a secure mode of operation for a wireless device and to establish a shared secret key with the wireless device, the shared secret key being utilized to output an encrypted message and the wireless device is configured to operate in a secure mode and an unsecure mode in support of two-way messaging, and the processor is further configured to obtain signal strength of the wireless network with respect to the wireless device and to determine a random seed based on the signal strength, the random seed being used to determine the shared secret key, and
- a communication interface configured to transmit the command to the wireless device to activate the secure mode of operation, wherein the secure mode of operation provides transmission of the encrypted message by the wireless device over the wireless network.
A method for communicating in a wireless network, the method comprising:
- switching from an unsecure mode of operation to a secure mode of operation;
- establishing a shared secret key with a cryptographic server over the wireless network in support of two-way messaging;
- generating an encrypted message using the shared secret key;
- obtaining signal strength of the wireless network;
- and
- determining a random seed based on the signal strength, wherein the random seed is used to determine the shared secret key.
A device for communicating in a wireless network, the device comprising:
- means for switching from an unsecure mode of operation to a secure mode of operation;
- means for establishing a shared secret key with a cryptographic server over the wireless network in support of two-way messaging;
- means for generating an encrypted message using the shared secret key;
- means for obtaining signal strength of the wireless network;
- and
- means for determining a random seed based on the signal strength, wherein the random seed is used to determine the shared secret key.
