Question 1: In which Somewhat Homomorphic Encryption schemes the plaintext space is defined over $\mathbb{F}_p$, where $p$ is a prime number.

It is said, in Somewhat homomorphic encryption the noise increases when homomorphic multiplication is used.

Question 2: Does this include multiplying a ciphertext by a plaintext? or just multiplying two ciphertexts?
