Systems and methods for encrypting and transmitting data packets using a unicast address
Disclosed herein are embodiments of systems, methods, and products comprising a computing device, which provides Efficient Data-In-Transit Protection Techniques for Handheld Devices (EDITH) to protect data-in-transit. An end user device (EUD) may generate a multicast data packet. The EDITH module of the EUD encapsulates the data packet in a GRE packet and directs the GRE packet to a unicast destination address of an EDITH Multicast Router included in an infrastructure. The EDITH module on the EUD double compresses and double encrypts the GRE packet. The EDITH module on the infrastructure decrypts and decompresses the double compressed and double encrypted GRE packet to recreate the GRE packet. The EDITH module on the infrastructure decapsulates the GRE packet to derive the original multicast data packet, and distributes the original multicast data packet to the multiple group member based on the multicast destination address included in the original multicast data packet.
1. A computer implemented method comprising:
generating, by a first computer, a data packet containing a group destination address;
encrypting, by the first computer executing inner encryption software, the data packet with an inner layer key, the inner encryption software corresponding to first encryption software of a router device having a unicast address;
encrypting, by the first computer executing outer encryption software, the data packet with an outer layer key, the outer encryption software corresponding to second encryption software of the router device having the unicast address; and
transmitting, by the first computer using the unicast destination address associated with the router device, the data packet to one or more target computers associated with the group destination address.
2. The method according to claim 1 , further comprising appending, by the first computer, the unicast destination address associated with the router device to the data packet.
3. The method according to claim 1 , further comprising executing, by the first computer, a software application configured to produce data for one or more data packets,
wherein the first computer generates the data packet based upon the data produced by executing the software application.
4. The method according to claim 1 , further comprising transmitting, by the first computer, at least one data packet of a plurality of data packets of a packet flow having uncompressed header data to the one or more target computers.
5. The method according to claim 1 , further comprising removing, by the first computer and from the data packet, one or more header fields consistent over a packet flow of a plurality of data packets.
6. The method according to claim 1 , further comprising re-encoding, by the first computer, one or more header fields of the data packet to reduce one or more field sizes, the one or more header fields inconsistent over a packet flow of a plurality of data packets.
7. The method according to claim 1 , wherein the inner layer key used by the first computer for the inner encryption software corresponds to a second inner layer key of the router device.
8. The method according to claim 1 , wherein the outer layer key used by the first computer for the outer encryption software corresponds to a second outer layer cryptographic key of the router device.
9. The method according to claim 1 , wherein the router device is a multicast router.
10. The method according to claim 1 , wherein the first computer is a mobile device configured for network communication via an ad hoc network.

transmit, using the unicast destination address associated with the router device, the data packet to one or more target computers associated with the group destination address.
12. The system according to claim 11 , wherein the first computer is further configured to append the unicast destination address associated with the router device to the data packet.
13. The system according to claim 11 , wherein the first computer is further configured to execute a software application configured to produce data for one or more data packets,
wherein the first computer generates the data packet based upon the data produced by executing the software application.
14. The system according to claim 11 , wherein the first computer is further configured to transmit at least one data packet of a plurality of data packets of a packet flow having uncompressed header data to the one or more target computers.
15. The system according to claim 11 , wherein the first computer is configured to remove, from the data packet, one or more header fields consistent over a packet flow of a plurality of data packets.
16. The system according to claim 11 , wherein the first computer is configured to re-encode one or more header fields of the data packet to reduce one or more field sizes, the one or more header fields inconsistent over a packet flow of a plurality of data packets.
17. The system according to claim 11 , wherein the inner layer key used by the first computer for the inner encryption software corresponds to a second inner layer cryptographic key of the router device.
