It is a broad process that includes various tools, techniques and standards to ensure that the messages are unreadable when in transit between two or more network nodes. Network encryption is the process of encrypting or encoding data and messages transmitted or communicated over a computer network. Encryption is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format — called cipher text. this helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the internet. It deals with developing and analyzing protocols which prevents malicious third parties from retrieving information being shared between two entities thereby following the various aspects of information security. An original message is known as the plaintext, while the coded message is called ciphertext. Another modern concept that will befuddle you if you do not understand public key cryptography is that of digital rights Cryptography, in networking and telecommunications, is the process of securely transmitting data over a network in such a way that if the data is intercepted, it cannot be read by unauthorized users. Define approaches and phases in cryptography development.

• the term cryptography is a greek word which means secret writing.

The process of converting plaintext to cyphertext is known as enciphering or encryption: In a simplest form, encryption is to convert the data in some unreadable form. The information cannot be read without a key to decrypt it. 3 cryptography is the science of using mathematics to encrypt and decrypt data. Network encryption is the process of encrypting or encoding data and messages transmitted or communicated over a computer network. High availability, one of the fundamental aspects of information security, cannot be ensured through the use of cryptography. Cryptography is the use of codes to convert data so that only a specific recipient will be able to read it, using a key. Symmetric key cryptography is a type of cryptography in which the single common key is used by both sender and receiver for the purpose of encryption and decryption of a message. An original message is known as the plaintext, while the coded message is called ciphertext. Restoring the plaintext from the ciphertext is deciphering or decryption.

The prefix crypt means hidden and suffix graphy means writing. Other methods are needed to guard against the threats such as denial of service or complete breakdown of information system. The outdated data encryption standard (des) has been replaced by modern encryption algorithms that play a critical role in the security of it systems and communications. Today, cryptography is digital, and the original text (plaintext) is turned into. Cryptography is the study and practice of techniques for secure communication in the presence of third parties called adversaries. An original message is known as the plaintext, while the coded message is called ciphertext. High availability, one of the fundamental aspects of information security, cannot be ensured through the use of cryptography.
