Abstract: A method for encrypting a plaintext string into ciphertext begins
by cipher block chaining (CBC) (70) the plaintext using a first key and a
null initialization vector to generate a CBC message authentication code
(MAC) whose length is equal to the block length. The plaintext string is
then cipher block chained (72) again, now using a second key and the
CBC-MAC as the initialization vector, to generate an enciphered string.
The CBC-MAC and a prefix of the enciphered string comprising all of the
enciphered string except the last block are then combined (74) to create
the ciphertext. The described mode of operation is length-preserving,
yet has the property that related plaintexts give rise to unrelated
ciphertexts.

Abstract: A HVAC system automates the process of calibrating the individual
branch flows of the system. For each branch of the system, a damper is closed and
flow values at the output of the prime mover and at the input of the damper are
measured. The damper is then opened 50% and again flow values at the output of the
prime mover and at the input of the damper are measured. A flow coefficient, which
correlates the flow difference measured at the output of the prime mover with the flow
difference measured at the input of the damper, is then determined. The flow through
each damper of each branch is calibrated in this manner, resulting in an overall
balancing of the HVAC system. The automated process of branch flow calibration
eliminates the tedious and time consuming process of both manual steps of measuring
the branch flows and determining the flow coefficients as was performed in the prior
art.
