Automatic Software Puzzle Generator and Shoulder Surfing Resistant System to Detect and Prevent Attacks

Computer Engineering

Network security refers to protecting the network and creating a secure platform for users. In traditional system, users entered text passwords to authenticate themselves which can be easily hacked if someone peeks over their shoulders and if graphical passwords is used then it can be easily remembered by human brains. In DOS attack, the target machine is flooded with continuous dummy request by the DOS attacker so as to overload the system and prevent the request from being fulfilled. Previously a client puzzle was used which demanded the client to solve a puzzle whose algorithm was generated in advance. So the client could solve this puzzle quickly. The proposed system for preventing shoulder surfing attack is shoulder surfing resistant system based on graphical passwords using PassMatrix technique. For DOS attack we are developing a software puzzle which generates the algorithm randomly only after the client request is received by server using puzzle core generation. Hence we will be implementing these two techniques to prevent and detect the attacks.
