Cryptographic Tunneling

What is Cryptographic tunneling? Cryptographic tunneling is a method in which education is transmitted from one network to an new(prenominal) in a secured manner. before nurture passes through the tunnel, it is broken into smaller descriptors. each frame is encrypted with an added work of security and encapsulation. The encapsulation is reverted at the destination with decryption of information, which is whence move to the desired destination (Tunneling, 2011). The Opened Systems connect (OSI) case is a great example of tunneling. The OSI model is dissever into septette layers and each layer provides a different task. The to a glare place graph is the OSI model (Petri, 2009). In the above chart selective information is transmitted and received. The drug user creates the selective information and now the user expects to shoot the info to another user or the desired destination. The info has to go through xiv go in exhibition to reach its destination. The first septet steps in for the contagious disease of the selective information and the undermentioned seven steps is for the receipt of the information. The steps below go forth show the process that the data has to go through in put to send the data as well as receiving the data at it final destination. info is created and then sent to the lotion layer (Layer 7).

The application layer is where different conference services and applications are provided. The data being transmitted coffin nail be transferred by file transfer, electronic messaging, virtual terminal figure access or any other forms of communications (Merkow, 2005). out front the data leave the application layer, supererogatory encr! yption and encapsulation is added to the data to give the data more security. nigh step for the data is the presentation layer (Layer 6). In this layer, speech and formatting of data distributes place. The presentation layer processes the data from the application layer so that no issue arises during the sending process. Protocols at this layer take care of manipulation tasks that transform data from one representation...If you want to get a full essay, order it on our website: OrderEssay.net
