Because a significant portion of the data's integrity depends on the users' ability to keep the keys secret, this encryption type is known as private key cryptography.You still need to decide the cipher methods to use to encrypt the data, even if you are successful in keeping the keys ...
The best analogy for symmetric encryption is a lockbox. To unlock a lockbox you must have the right key. In the physical world, this key is usually a metal object. In the world of cryptography, this key is aset of random bits. Whatever is inside the lockbox is confidential and protecte...

In modern cryptography exist the concept of symmetric and asymmetric cryptography. Symmetric cryptography means that you use the same key for encryption and decryption. In asymmetric cryptography you have two keys, one is for encryption, known as the public key, and the other one is for decryption...
We consider symmetric encryption as the cryptographic primitive in protocols. Handling this primitive has so far received comparatively less attention in approaches striving to unite the formal and computational models of cryptography.doi:10.1109/secpri.2004.1301316Laud...
5.1Symmetric cryptography Also known as shared key cryptography[5], as the name infers, there exists symmetry in this kind of cryptography between the encryption and decryption keys, i.e., these both are the same. The key with which the message in plain text has been encrypted will also be...
Cryptography is a method of using advanced mathematical principles to store and transmit data in a particular form so that only intended recipients can read and process it. Encryption is a key concept in cryptography – It is a process where a message is encoded, known as ciphertext so that ...
Asymmetric encryption, on the other hand, uses two keys: a public key for encryption and a private key for decryption.RSA(Rivest-Shamir-Adleman) andECC(Elliptic Curve Cryptography) are popular asymmetric algorithms. In this system, the public key can be openly distributed, while the private key...
Symmetric encryption is a form of computerized cryptography using a singular encryption key to guise an electronic message. Its data conversion uses a mathematical algorithm along with a secret key, which results in the inability to make sense out of a message. Symmetric encrpytion is a two-way...
These principles are valuable not just for cryptosystems and resistance via encryption, but for security strategies generally. Cryptography is one part of the strategy that is most suited to rigorous proof, and so fewer assumptions may be needed here than elsewhere. But all strategies would benefit...
