Q1. Describe the concept of asymmetric cryptography. How asymmetric encryption works? Also explain its types.
Key Points:
- Asymmetric cryptography uses a mathematically related public-private key pair.
- Public key encrypts data; corresponding private key decrypts the encrypted data.
- Private key is kept secret, public key is freely distributed to others.
- RSA algorithm relies on factoring large numbers for encryption and digital signatures.
Answer: Asymmetric cryptography, often called public-key cryptography, is a fundamental concept in modern secure communication that employs a pair of mathematically related keys: a public key and a private key. Unlike symmetric encryption which relies on a single shared secret key, asymmetric encryption ensures that knowing one key does not reveal the other, thereby overcoming the critical problem of secure key distribution inherent in symmetric systems. Each user generates their own unique key pair. T...
