comment Universal hashing techniques based on matrix multiplication
Proving \epsilon-universality of random matrix hashing sounds an execise. I once found proofs in Shoup's textbook.

Do you need more explanation or easier one, e.g., "SearchLWE vs DecisionalLWE"?

comment Is there a public-key cryptography method that enables public keys to be much smaller than private keys?
Stretching a secret key often appears in the context of leakage-resilient cryptography.

comment Is the strength of RSA over quadratic or other cyclotomic fields as strong as over the integers?
Note: Scheidler-Williams (DCC 1995) and Takagi-Naito (IEICE Trans. J81-A1, 19980in Japanese) may be relaed to this question and discuss security.
