W4261 Introduction to Cryptography: Homework

Submission Instructions:

• Solutions must be typed and submitted in PDF format.
• LaTeX in highly recommended, but not required (you can edit this sample file, and you need this class file to generate a pdf. Prof. Rocco Servedio created these templates for his Introduction to Computational Learning Theory class).
• LaTeX resources here!.
• Use a separate page for each problem.
• The filename must contain your UNI.
• The file should be submitted through drop box feature in Courseworks (starting with homework 2).

• You are allowed 6 late days for the semester. Late days are counted in increments of 24 hours, and cannot be subdivided.
• You may consult outside references when doing the homework, as long as every source (other than the textbook and your class notes) is properly referenced, and you write up the solutions yourself in your own words. However, the problems are designed with the intention that the material seen in class (and the corresponding sections of the textbook) should be sufficient to solve them.
• You may discuss the homework problems and possible solution approaches in groups of at most 3 students, as long as all discussion partners are listed on your homework. Discussion groups may be used for studying the material and brain-storming, but cannot involve one student telling the others how to solve the problem, and no student may look at written solutions of any other student.
• The above use of outside sources and participation in discussion groups is allowed (and encouraged) for the purpose of further understanding the material and working out how to solve the homework, but not for the purpose of finding ready solutions that you can use. If you are in doubt (e.g., you finished reading an unsolicited email from your high-school friend, only to realize it contains the full solution to one of the problems on the homework), ask the professor.
• All students are assumed to be aware of the computer science department academic honesty policy.

• Homework 1 (tex source file) is due Thursday 9/14/12 (before midnight). No late homework will be accepted. No collaboration of any kind is allowed on this homework (if you have any question, ask the professor or the TA). This homework can be submitted either using the dropbox feature on courseworks, or by email to the TA. If you must, we will accept scanned legibly hand written solutions for this homework only.
• Homework 2 : due Tuesday 10/9/12 by 11:59pm.
• Homework 3 : (tex source file) due Thursday 10/25/12 by 11:59pm. Update: due date has been extended to Tuesday 10/30/12 at 11:59pm, with the stipulation that at most one late day may be used for this homework.
• Homework 4 : due Tuesday 11/27/12 by 11:59pm.
• Homework 5 : due Sunday 12/16/12 by 11:59pm. You may use up to 3 late days for this homework (if you haven't yet exhausted your late days for the semester). This homework counts as half for grading purposes. No collaboration of any kind is allowed after the take home final is posted on Friday 12/14.
• Example Homework 5 from last year. This does not need to be submitted, and is included here for your practice only. Solutions will be published on courseworks.
