The Evolution Of Ethernet To 800G And MACsec Encryption


Ethernet is a frame-based data communication technology that employs variable-sized frames to carry a data payload. This contrasts with long-haul Optical Transport Networks (OTN) that use fixed-sized frames. The size of Ethernet frames ranges from a minimum of 60 bytes up to 1500 bytes, and in case of jumbo frames, up to 9K bytes. A frame is a Layer 2 data container with the physical addresses ... » read more

Securing Data In Motion With MACsec


For end-to-end security of data, it must be secured both when “at rest” (processed or stored in a connected device) and when it is “in motion” (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides that foundation upon which all data and device security is built. For example, the security of applications builds on an uncompromis... » read more

MACsec Fundamentals: Securing Data in Motion


For end-to-end security of data and devices, data must be secured both when it as rest (stored on a connected device) and when it is in motion (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides that foundation upon which all device security is built. Similarly, MACsec security anchored in hardware at the foundational communication l... » read more
