Today's reading was about secret splitting and threshold schemes, it was not too hard to understand. It is based on the number of points needed to define a polynomial. The method of recovery is the chinese remainder theorem for a matrix equation. The really cool part is the situation of multiple companies having a system that requires representatives from each company present to figure out a secret. That one is way cool. It seems similar to the linear combination of solutions to a differential equation or finding a basis to a vector space.
To be truthful, I feel that the most difficult thing in this section is knowing that the test is tomorrow and this is on the test after that. But I thought it was really cool and I look forward to having a homework assignment about threshold schemes.
