Abstract
A method includes receiving a data packet including a header having a structure from an operating system at a virtualization layer, where the virtualization layer is above a physical layer and below all other layers. The method also includes performing an operation on a portion of the data packet other than the header, thereby creating a modified data packet and maintaining the original header structure. The method further includes transmitting the modified data packet, including the original header structure, to the physical layer.
Claims9
A method, comprising:
- receiving an Ethernet data packet comprising a header having a structure from an operating system at a virtualization layer, the virtualization layer being above a physical layer and below all other layers;
- performing an operation on a portion of the Ethernet data packet other than the header, thereby creating a modified data packet and maintaining the original header structure;
- accessing, by the virtualization layer, an encryption modulation chart;
- updating the virtualization layer to apply a first encryption algorithm to a first portion of the Ethernet data packet and to apply a second encryption algorithm to a second portion of the Ethernet data packet;
- selecting, by the virtualization layer, an encryption algorithm from the encryption modulation chart;
- applying different encryption algorithms, by the virtualization layer to the Ethernet data packet at the same point in time;
- transmitting the modified data packet, including the original header structure, to the physical layer.

A method for device authentication, the method comprising:
- sending a request from a device to an authentication client;
- receiving a response including a virtualization client,
- obtaining, by the virtualization client, unique device identification information from the device;
- sending the unique device identification information to the authentication client, thereby authenticating the device at the authentication client;
- sending a request for user authentication information from the authentication client to the virtualization client;
- sending user authentication information from the device to the authentication client, thereby authenticating a user of the device at the authentication client;
- and
- authenticating the user by using the user authentication information and unique device identification information to authenticate the user;
- receiving an Ethernet data packet comprising a header having a structure from an operating system at a virtualization layer;
- and
- performing an operation on a portion of the Ethernet data packet, other than the header, thereby creating a modified data packet and maintaining the original header structure, wherein the operation comprises:
- encrypting the portion of the data packet while not encrypting the original packet header structure;
- updating the virtualization layer to apply a different encryption algorithm to the portion of the Ethernet data packet;
- and
- selecting and applying different encryption algorithms, by the virtualization layer, to the Ethernet data packet at the same point in time;
- transmitting the modified data packet, including the original header structure, to a physical layer of the device.
