Can someone explain the green highlight to me please? Sorry that I can't type much because this is the final week. Thanks.
RSA encryption is a form of public key cryptography that is widely used for secure communication and data encryption. It was developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman, and is named after their last names.
The small step in the proof of RSA encryption is the calculation of the private key, which is used to decrypt the encrypted message. This step involves finding the modular inverse of a number using the extended Euclidean algorithm.
This small step is important because it ensures that the private key is unique and can only be calculated by someone who knows the factors of the public key. This makes it difficult for an attacker to decrypt the message without the private key.
The small step in the proof of RSA encryption makes it secure by ensuring that the private key is difficult to calculate without knowing the factors of the public key. This means that even if an attacker intercepts the encrypted message, they will not be able to decrypt it without the private key.
While the small step in the proof of RSA encryption is generally considered secure, there have been some weaknesses identified in certain implementations. For example, if the public key is not generated properly, it can make it easier for an attacker to calculate the private key. It is important to use a secure implementation of RSA encryption to avoid these weaknesses.
