BCS Exam CISMP-V9 Topic 2 Question 89 Discussion

RSA (Rivest-Shamir-Adleman) is a widely accepted asymmetric encryption algorithm. Unlike symmetric algorithms, which use the same key for both encryption and decryption, asymmetric algorithms use a pair of keys -- a public key for encryption and a private key for decryption. This method allows for secure key exchange over an insecure channel without the need to share the private key. RSA operates on the principle that it is easy to multiply large prime numbers together to create a product, but it is hard to reverse the process, i.e., to factorize the product back into the original primes. This one-way function underpins the security of RSA.
