A cryptographic attack is a method for circumventing the security of a cryptographic system by finding a weakness in a code, cipher, cryptographic protocol or key management scheme. This process is also called "cryptanalysis".

There are main two types of security attack in cryptography: Passive Attack and Active Attack. In this video, I have explained Passive attack in network security. Passive attack is divided into two types: Traffic Analysis and Release of message content.

Traffic Analysis: Intruders checks the contents of message or other information, even if they captured the message but could not extract the information from the message. The opponent might observe a pattern of message to get the location, or any clue regarding the origin of message. Passive attack is very difficult to detect, because they do not involve any alteration of the data.

Release of message content: The goal of the attacker is to obtain information that is being transmitted. A telephonic conversation, an electronic mail message and a transferred file may contain sensitive or confidential information. In this type of passive attack, message cannot modify by attacker. Attacker just read the message and then release the message. There may be a delay to reach message at receiver end.
