The key exchange protocol is considered an important part of the cryptographic mechanism to protect end-to-end communications security. An example of the key exchange protocol is the exchange of Hellman files and keys [DIF 06, STA 10], which is known to be vulnerable to attack. To ensure a secure key exchange, [CHI 11] proposed a three-way exchange and agreement protocol (TW-KEAP). This minutes provide both parties to the communication with the same key to meeting secure communication. The TW-KEAP concept stems from the four-part key exchange protocol, in which two customers are registered among the two different servers, and has expanded the benefits of the previous two protocols. If this key agreement requires random bytes, they will be kept as a source of coincidence with the SecureRandom implementation of the installed vendor with the highest priority. (If none of the installed vendors provides an implementation of SecureRandom, a random source provided by the system is used.) FCPAP is an optional password-based authentication and key exchange protocol used on Fibre channel networks. FCPAP is used to authenticate the ports of the fiber chain. The most important agreement is that the key source must be such that at the end of the process, two specific entities know the key and only these. A perfect example is the Diffie-Hellman protocol, in which both parties use randomness to create data elements, exchange some of these elements, and make some calculations that end up getting the same result, while external observers are not impressed. Sharing hardware resources can be another data protection issue. Some research efforts focus on the analysis and restoration of compromised systems.
To solve this security problem, there are two solutions for data protection: one is to isolate the data at the application level [JAI 08] and the other is to isolate the data at the hardware level [AZA 11]. The keys involved in setting up a common secret key are created by one of the key generators (KeyPairGenerator or KeyGenerator), a KeyFactory or following an intermediate phase of the key memorandum of understanding.
