Validating User Flows to Protect Software Defined Network Environments

Algorithm 1

Steps involved for prevention of spoofing attack.

Step 1. Start

Step 2. Controller updates the states of switches

Step 3. Controller requests hash functions

Step 4. Switches response with hash functions

Step 5. Hash validation

 If (Original hash)

Creates secure link (Goto Step 6)

Else

Invalid switch

Step 6. Begin migrating the flow between switches

Step 7. End
