Problem Set, In class and out. Due September 8 2016
Write programs to derive monomer probabilities and pair probabilities. It would also be good to write
a program to calculate Psi or Phi. The file 3boat10.txt is a relevant source of plaintext.

What is Parallel and Distributed
computing?
Solving a single problem faster using multiple
CPUs
E.g. Matrix Multiplication C = A X B
Parallel = Shared Memory among all CPUs
Distributed = Local Memory/CPU
Common Issues: Partition, Synchronization,

Stream Ciphers Part 2
Stream ciphers are an approximation to one time ciphers where the key is derived by a
pseudo-random algorithm rather than a truly random source. The more random the
initialization of the pseudo-random source, the be

Perfect Secrecy
Describing Information
Given a set of symbols (e.g. an alphabet like a,b,c,.) then we need to describe the
properties of a sequence of symbols drawn from . In order to do this we need to posit a
probabilistic model for how th

Public Key Ciphers
Conventional symmetric ciphers require that both parties, the sender and the recipient
have the same secret information which is the key to the cipher. Indeed while a one time
system gives perfect secrecy, the
