March 04, Tu, (Lecture 10): We discussed the specific hash function SHA-1, which
produces a 160-bit digest. We covered SHA-1 with analogy with MD-5. We also
discussed an attack on hash functions that is based on the birthday paradox.
March 07, Th (Lecture 11): We started discussing MACs. We covered a "nested
hash function" called HMAC and briefly discussed the security of this scheme.
We covered some topics to review for the midterm.
