Overview:
The term Cryptography are used to provide a good range for secure communication in the presence of malicious or virus or third-parties. here a term is used to transform the input in the form of key which is used is encryption. The provided and given algorithm will always transform the same plaintext into the same cipher text just only in case if same key is used.
The given Algorithms are considered as secure if an attacker or hacker cannot determine any properties of the plaintext or key, given the cipher text that is used. When an attacker attacks may not be able to get anything about a key given a large number of plain text to cipher text which is combination of using the key.
Which the problems does cryptography covers:
Cryptography is a way secure system should provide several benefits such as confidentiality, integrity, and availability of data as well as authenticity and ease to everyone in work.in this case when using the correct then crypto helps to provide these assurances to the customers. The term that is used as Cryptography makes confidentiality and integrity of both data that in working as well as data at rest in it. It is also authenticate all senders and recipients to one another and protect against repudiation and any error chances.
The provided Software systems mostly have multiple end points and used typically multiple clients and one or more back-end servers that cover all the situation. When we talk about client and server communications take place over networks that cannot be trusted and not much useful. The way in which discussion occurs over an open or public network such as over the Internet, or private networks which may be external attackers or virus insiders that may cause errors.
Mostly It can protect the overall communications that travels between untrusted networks. So there are two main types of attacks that mostly disturb and damage the overall performance and it is to carry out on a network. The one type is Passive attacks involve an attacker which is done nothing only listening on a network segment and attempting to read sensitive information as it travels and leak it to others. This type of attacks may be online in which attack reads the real time data and interrupts the data language too or offline in which attacker attacks and capture the data and damage it. The Second type is Active attacks which is involve an attacker disturbing a client or server or interrupting the whole communications in traveling and viewing or modifying the whole contents before passing them to travel in their path before approaching their actual destination.
By using cloud only improves the confidentiality and integrity protections offered by cryptographic protocols that is used to protects the whole network. All depends on the protections which is provided to confirm that users are actually communicating with the systems as secure. When people trust then they easily communicates with one each other via through the internet using different apps like when people trusted they are sending your online banking password to your bank or someone else.
