Methods and systems for securing data are provided. For example, one method includes receiving at an adapter, data with a first type of error protection code from a host memory of a computing device; adding by the adapter a second type of error protection code to the data before removing the first type of error protection code; generating by the adapter, a frame header for the data with a protocol specific protection code and a third type of error protection code, where the third type of error protection code is generated without using any frame header field; encrypting by the adapter, the data, the protocol specific protection code and the third type of error protection code; and transmitting by the adapter, the encrypted data with encrypted protocol specific protection code and encrypted third type of error protection code to a receiving adapter coupled to the adapter by a network link.

Methods and systems for overlapping protection domain in network devices

Machine implemented method and system for processing frames received by a network device from another network device via a network link are provided. The network device is configured to maintain a data structure to determine a tag size of a tag received in a frame header of a frame received by the network device; determine if the tag size is less than a fixed programmable size; insert a blank character to increase the tag size to the programmable size; and process the frame with the tag having the programmable size.

Method and system for variable length tag processing

Method and system for an adapter operationally coupled to a host system and a network is provided. The adapter includes an internal memory that can be configured in a first mode to operate as a dedicated random access memory used by a main processor of the adapter; or configured in a second mode to operate both as a random access memory used by the main processor and also used for storing information received from the network. The method includes enabling the second mode of the internal memory so that the internal memory is configured to operate both as random access memory for the main processor and for storing information received from the network.
