In practice, the first two problems can arise when short ASCII messages are sent. As soon as they see ciphertexts that match the ones in their dictionary, the attackers can then use this dictionary in order to learn the content of the message. The attacker can then observe the communication channel. They can make a dictionary by encrypting likely plaintexts under the public key, and storing the resulting ciphertexts. Therefore, an attacker can successfully launch a chosen plaintext attack against the cryptosystem. RSA encryption is a deterministic encryption algorithm.In this case, ciphertexts may be easily decrypted by taking the eth root of the ciphertext with no regard to the modulus. Choose two different large random prime numbers p may be strictly less than the modulus n.The keys for the RSA algorithm are generated the following way: The discrete logarithm is about finding the smallest x that satisfies the equation, when a b and n are provided This works much like the normal logarithm: The difference is that only whole numbers are used, and in general, a modulus operation is involved. RSA uses a concept called discrete logarithm.A one-way function that is easy to compute finding a function that reverses it, or computing this function is very difficult.RSA use a number of concepts from cryptography: 5 Deriving RSA equation from Euler's theorem.Calculating the private key from the public key is very difficult. Messages encrypted using the public key can only be decrypted with the private key. The public key can be known to everyone- it is used to encrypt messages. RSA involves a public key and private key. It is also a key pair (public and private key) generator. The algorithm is based on the fact that finding the factors of a large composite number is difficult: when the factors are prime numbers, the problem is called prime factorization. This is also called public key cryptography, because one of the keys can be given to anyone. Asymmetric means that there are two different keys. It is an asymmetric cryptographic algorithm. RSA (RivestвЂ“ShamirвЂ“Adleman) is an algorithm used by modern computers to encrypt and decrypt messages.
