Another typo on exercise sheet 02

Written on 17.01.19 by Nico Döttling

In exercise 4 DEC outputs either m or \bot (not 1 or 0). Thx to Bohdan

Another update of exercise sheet 2

Written on 14.01.19 by Nico Döttling

- In Exercise 2 we require the group G to be of prime order (in fact, any composite order with large factors would do)

- In Exercise 3 we require that the field F has size 2^\secparam (instead of \secparam)

Exercise Sheet 2 updated

Written on 11.01.19 by Nico Döttling

Fixed some unclarities: In exercise 2 added the condition m_0 \neq m_1 to the binding property, in exercise 4 a \gamma was missing in the description of DEC.

Thanks to Florian and Jesko

Exercise Sheet 01 Updated

Typos in the exercise sheet have been fixed. Also, due to a suggestion I've added an extra exercise (1b) which shows why we can assume without loss of generality that adversaries are deterministic.
