General definition

Public-key algorithm of cryptography, sometimes names as asymmetric cryptography. It is a class of cryptographic algorithms which uses two separate keys, one of which is known only by one side (secret or private) another one is available for publicity (public). These 2 keys are different, but they are connected with some mathematical operations. The public key is usually used to encrypt(code) data or to verify and confirm a digital signature. The private key is used to decode (decrypt) data or to create a digital signature. The term asymmetric describes this algorithm because different keys are used to run the ...

Introduction

Cryptography is a mathematical technique for encrypting and decrypting data. Cryptography enables one to store and transmit sensitive information across public insecure networks so that no one else can access the information apart from the authorized persons, i.e., the sender and the intended recipient (Martin, 2012). Cryptography uses a cryptographic algorithm. A cryptographic algorithm is a mathematical function used during the encryption and decryption process. The algorithm works together with a key to transform plaintext into encrypted text. The security of encrypted information depends on two things: the secrecy of the key used and the strength of the cryptographic algorithm employed (Stallings, 2013).

Question 1

...

The symmetric and asymmetric key encryptions are different operations,which functions in different circumstances, for different applications and different attack models. Therefore, it is not sensible enough to say that either symmetric or asymmetric is better than the other in terms of computer system and data security. If some measurable security could be available, then it could have been easy to tell which key is better. However, this measure is not simple to describe ( Sudha, 2012). The encryption key length or size defines the number of bits of the given security key that is employed in the algorithm ...
