With the help of a block diagram explain the RSA algorithm for digital signature ?
Digital signatures are like electronic “fingerprints.” In the form of a coded message, the digital signature securely associates a signer with a document in a ... -
With the help of block diagram explain DES?

Explain an Diffie-hellman key exchange algorithm?
Purpose is to enable two users to securely exchange a key that can then be used for subsequent symmetric encryption of messages The algorithm is ... -
What is the RSA algorithm?
The RSA algorithm is an asymmetric cryptography algorithm; this means that it uses a public key and a private key (i.e two different, mathematically linked keys). As their names suggest, a ... -
Describe the main applications of Public key cryptography?
Public-key cryptography, or asymmetric cryptography, is an encryption scheme that uses two mathematically related, but not identical, keys - a public key and a private ... -
Explain birth day attack ?
A birthday attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used ... -
