Can public key cryptography be used to solve problem of the key distribution?
Public key cryptography, also known as asymmetric cryptography, is a fundamental aspect of modern cybersecurity, and it addresses the critical problem of key distribution. In classical cryptography, the secure exchange of keys between parties is a significant challenge. Public key cryptography provides a solution to this problem by using a pair of keys: a public

How does the RSA cryptosystem address the problem of secure key distribution that is inherent in symmetric cryptographic systems?
The RSA cryptosystem, named after its inventors Rivest, Shamir, and Adleman, is a cornerstone of modern public-key cryptography. One of the primary challenges in symmetric cryptographic systems is the secure distribution of keys. Symmetric systems require both the sender and the receiver to share a secret key, which must be exchanged securely before any encrypted
