Plaintext is what you want to protect; ciphertext should … There are a number of attacks against plain RSA as described below. • When encrypting with low encryption exponents (e.g., e = 3) and small values of the m (i.e., m < n ), the result of m is strictly less than the modulus n. In this case, ciphertexts can be decrypted easily by taking the eth root of the ciphertext over the integers. • If the same clear-text message is sent to e or more recipients in an encrypted way, and the receivers share the same exponent e, b…
