Abstract
In a method of verifying membership in an operator infrastructure of a destination server of frames received by a gateway of the operator infrastructure, the gateway receives frames transmitted over a first network by a communication device, and performs a first decryption of the received frames using a gateway private key stored in the gateway, termed a gateway decryption. A successful decryption of a frame by the gateway indicates that the decrypted frame belongs to the operator infrastructure.
Claims6
A method of verification of membership in an operator infrastructure of a destination server of frames received by a gateway of the operator infrastructure, the method of verification comprising the following acts performed by the gateway:
- receiving frames transmitted over a first network by a communication device;
- and
- performing a first decryption of the frames received by using a gateway private key stored in the gateway, termed a gateway decryption, a success of the gateway decryption of a frame indicating that the decrypted frame belongs to the operator infrastructure.
A method of filtering frames received by a gateway of a network infrastructure, the method of filtering comprising the following acts performed by the gateway:
- receiving at least one frame from a communication device via a first communication network;
- decrypting the frame using a gateway private key stored in the gateway to produce at least one decrypted frame;
- and
- in response to the act of decrypting being successful, transmitting the at least one decrypted frame to a network server of the network infrastructure via a second communication network.
A method of generating asymmetric gateway keys, comprising the following acts performed by a key generating device:
- upon the attachment of a communication device to an operator infrastructure, generating a gateway public key and a gateway private key pair;
- transmitting the gateway public key of the pair to the communication device;
- and
- transmitting the gateway private key of the pair to at least one gateway of the operator infrastructure.
A gateway of a network operator infrastructure, the gateway comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions stored thereon which when executed by the processor configure the gateway to perform acts comprising:
- receiving at least one frame from a communication device via a first communication network;
- decrypting the frame using a gateway private key stored in the gateway to produce at least one decrypted frame;
- in response to the act of decrypting being successful, transmitting the at least one decrypted frame to a network server of the network infrastructure via a second communication network.
