Compare and contrast symmetric and asymmetric encryption with some detail for each of the topics listed below. a) the number of keys involved b) key management and distribution c) operations performed on data d) relative speed e) other relevant items

Solution

Symmetric key encryption may be defined as an algorithm which deals with the cryptography for the encryption of data with the use of cryptographic set of keys as plain text and for decryption of modified cipher text. Both keys are kept in private for both shared end to end nodes where data is being transferred by users. Basically encryption is being done in order to eradicate of data theft by third users or intruders due to malicious activity. For the number of keys used in the symmetric and asymmetric encryption, it depends upon the number of users, that everybody is required to read same message of with the help of same key. Basically in asymmetric key cipher uses two keys for encryptions one is RSA and one we call private key. Here public key is with everyone and anybody can use it but as far as private key is concerned it is used by only authorized/owner user.

Here i can quote the number of keys used between the nodes in order to have secure communication is n²

n here can be denoted as n number of nodes and evrry node has one public key for the execution of encryption and similarly every node here n-1 private keys for the execution of decryption

therefore; 1+(n-1)=n keys

n here as above stated as number of nodes participating in communication, so finally number of keys that we needed for encryption = n*n=n²

Similarly for asymmetric key cryptography the number of keys to be required is 2n
