Level 3 RSA Course - Understanding RSA Encryption
When it comes to cryptography, RSA encryption is a fundamental concept that plays a crucial role in securing data transmission over the internet. In this article, we will delve deep into the intricacies of RSA encryption at Level 3 RSA course.
Introduction to RSA Encryption
RSA encryption is named after its inventors, Ron Rivest, Adi Shamir, and Leonard Adleman, who introduced the algorithm in 1977. It is a public-key encryption method that uses a pair of keys - a public key for encryption and a private key for decryption.
How RSA Encryption Works
Here is a simplified explanation of how RSA encryption works:
- Generate two large prime numbers, p and q.
- Calculate n = p * q, where n is the modulus.
- Calculate φ(n) = (p-1) * (q-1), where φ is Euler's totient function.
- Select an integer e such that 1 < e < φ(n) and gcd(e, φ(n)) = 1. This will be the public key exponent.
- Calculate d as the modular multiplicative inverse of e modulo φ(n). This will be the private key exponent.
- The public key is (n, e) and the private key is (n, d).
Benefits of RSA Encryption
RSA encryption offers several benefits:
- Secure data transmission
- Authentication
- Non-repudiation
- Key exchange
