I will not hand out letter grades during the course, just points. Your final grade will be determined by the total points you earn, weighted as shown above, and converted to a letter using this scale:

Frequently Asked Questions
I will record your grades for the assignments, as well as your final letter grade, in a grade file. Each student will have his or her own grade file. Each grade file will be encrypted with a different secret key for each student. The encrypted grade files will be posted on the course web site. Since no one can decrypt the grade file without the secret key, your personal grade information remains confidential despite being posted on the web site.
To decrypt your grade file, you will have to obtain the secret key from me, in person. Come to my office, show me your student ID, and I will give you your secret key. It is your responsibility to safeguard your secret key. If anyone else discovers what your secret key is, they will be able to decrypt and examine your grade file. Treat your secret key as you would your student ID, driver's license, or credit card. If you lose your secret key or suspect someone else has discovered it, see me, in person, to get a new secret key.
When I have finished grading each assignment, I will post an announcement on the What's New page that the grades are available.
For further information, see Encrypted Grades.
Discussing your grades: If you have questions about or want to discuss your grades, you must come see me in person. Either visit me during office hours or make an appointment. I will not answer questions about or discuss your grades via email.
The required textbook is Christof Paar and Jan Pelzl, Understanding Cryptography: A Textbook for Students and Practitioners (Springer-Verlag, 2010). A free online version is available from the SpringerLink database via the RIT Wallace Library web site.
You are responsible for learning, and will be tested on, the textbook chapters listed in the Course Schedule as well as Structural Attacks on Block Ciphers and Randomness. While I may not cover all the required reading material in class, you are nonetheless responsible for knowing it.
To help you learn the course material and prepare for the homeworks and final exam, Exercises (password required) are posted on the course web site, along with the solutions. I strongly recommend you do the problems before looking at the solutions, then check your work afterwards.
Accessing the exercises and solutions on the course web site requires authentication with a specific username and password. (This is not the same as your Computer Science Department account, and this is not the same as the secret key for decrypting your grade file.) The username and password will be announced in class and will also be listed in your grade file. Please observe the following restrictions:
There will be seven biweekly homeworks. Homeworks will be posted on the course web site on the dates shown on the Course Schedule. Homeworks will be due at 11:59pm on the dates shown on the Course Schedule. The homeworks will be submitted via email. The date/time at which your email message arrives in my inbox will determine whether the homework meets the deadline. Details of each homework, including grading criteria, will be provided when the homeworks are assigned.
40% of your final course grade will be based on your five best homework scores, 8% each.
Help with your homeworks: I am willing to help you answer the homework questions. However, you must come see me in person. Either visit me during office hours or make an appointment. I will not help you with homeworks via email. If it's the evening of the homework deadline and I have gone home, you are on your own. Plan and work ahead so there will be plenty of time for me to help you if necessary.
Late homeworks: I will not accept a late homework. Late homeworks will receive a grade of zero. (Homeworks are not included in my policy on extensions.)
Plagiarism: Each homework must be entirely your own work. I will not tolerate plagiarism. See below for my policy on plagiarism.
You will write a research survey paper in two parts. Each part will be due at 11:59pm on the date shown on the Course Schedule. The paper will be submitted via email. The date/time at which your email message arrives in my inbox will determine whether the paper meets the deadline. For further information, see the Research Paper assignment.
Late paper: I will not accept a late paper unless you arrange with me for an extension. See below for my policy on extensions. A late paper will receive a grade of zero.
Plagiarism: The paper must be entirely your own work. I will not tolerate plagiarism. See below for my policy on plagiarism.
There will be a two-hour final exam during the Institute examination period, at the date and time shown on the Course Schedule. The final exam will be open book, open notes, open electronics. The final exam will cover material from the entire course. The final exam will involve numerical calculations; be sure to bring a calculator.
I will not hand back the final exam. To see how you did on the final exam, you may visit me in my office.
Absences: If you are absent from the final exam, your final exam will receive a grade of zero unless before the start of the final exam you arrange with me to take the final exam at another time. I am normally willing to permit this only for absences due to illness or unforeseen personal emergency. However, if you feel you have a valid reason for your absence, please discuss it with me. Appointments, job interviews, career fairs, vacations, trips home, and other activities you schedule are not valid excuses for absence. You have an obligation to this course, and you must schedule other activities so as not to interfere with the final exam.
Scheduling conflicts: If you have a final exam scheduling conflict, please refer to the University Policies, Section D11.0, "Final Examination Policies." You must submit a written request for rescheduling to the head of your home department, with a copy to your instructor, by the last day of the tenth week of classes.
There will be two programming projects to be written in Java. The projects will be assigned on the dates shown in the Course Schedule. The projects will be due at 11:59pm on the dates shown in the Course Schedule. The projects will be submitted via email. The date/time at which your email message arrives in my inbox will determine whether the project meets the deadline. Details of each project, including grading criteria, will be provided when the projects are assigned.
Help with your projects: I am willing to help you with the design of your project. I am willing to help you debug your project if the code isn't working. However, for help with design or debugging issues you must come see me in person. Either visit me during office hours or make an appointment. I will not help you with design or debugging issues via email. If it's the evening of the project deadline and I have gone home, you are on your own. Plan and work ahead so there will be plenty of time for me to help you if necessary.
I will answer general questions about the project via email, such as requests to clarify or interpret the project requirements.
Late projects: I will not accept a late project unless you arrange with me for an extension. See below for my policy on extensions. Late projects will receive a grade of zero.
Plagiarism: Each project must be entirely your own work. I will not tolerate plagiarism. See below for my policy on plagiarism.
Resubmission of projects: If you so choose, you may submit a revised version of your project after you have received the grade for the original version. However, if the original project was not successfully submitted by the (possibly extended) deadline or was not entirely your own work (i.e., plagiarized), you are not allowed to submit a revised version. There will be a grading penalty for resubmitting a project. Details of the resubmission requirements will be provided when the projects are assigned.
The rules for extensions are:
|If you request an extension:||You will receive an extension of:|
|3 days before the deadline date||3 days|
|2 days before the deadline date||2 days|
|1 day before the deadline date||1 day|
|On the deadline date||1 day|
|When asking for an extension, I would appreciate some basic courtesy. Too many students send me a rude message like "I need an extension." The polite way to ask for an extension is, "May I please have an extension for Quiz 1?"|
The intent of this policy is not to give everyone an automatic 3-day extension for every assignment. The intent of this policy is to accommodate students who plan and work ahead on the assignments but experience an unforeseen last-minute difficulty, and to penalize students who do not plan and work ahead. If you put off working on an assignment and get sick or suffer a computer breakdown at the last minute, I am not going to give you more time than stated above. You should have been working ahead so you would have been finished before the last minute.
I am willing to waive the assignment deadlines, including extended deadlines as described above, in extraordinary circumstances. I am normally willing to permit this for reasons of illness or unforeseen personal emergency that prevent you from working on the assignments for an extended period of time. However, if you feel you have a valid reason for waiving a deadline, please discuss it with me.
The following policies apply to deadline waivers:
If you need to withdraw from the course, you must do so by the Institute withdrawal deadline as listed in the Institute calendar and the Course Schedule. You can do this via SIS, and you do not need my approval.
After the Institute withdrawal deadline, to withdraw from the course you must obtain approvals, from me among others. However, I will not approve a course withdrawal after the Institute withdrawal deadline for any reason. If you're going to withdraw, make up your mind to do it before the deadline.
My email address is email@example.com. To deter spambots, the email address is obfuscated. If you copy and paste my email address from this web site, it will not work. If you type in my email address by hand, it will work.
I apply spam filtering on incoming email. To get your email past my spam filters and into my inbox:
I reply in a timely manner to all emails that get past my spam filters and into my inbox. Emails blocked by my spam filters go into a separate spam folder. I do not reply in a timely manner to emails in my spam folder.
It is your responsibility to format your emails so that they get past my spam filters. This includes assignment submissions and extension requests as well as general questions. If I have not responded to your email within one business day (i.e. not counting weekends), contact me again.
For further information, see "Contacting Me."
You may use any resources you wish to do the assignments, including resources discussed in class and resources you find on your own. You may discuss the assignments at a general level with others in the class. However, each assignment you turn in must be entirely your own work. You are not allowed to collaborate with anyone else on any assignment. You are not allowed to use any current student's work, past student's work, or any other person's work in any way when working on your assignments.
I will not tolerate plagiarism. If in my judgment an assignment is not entirely your own work, you will receive, as a minimum, a grade of zero for the assignment. Plagiarism incidents will result in disciplinary action in accordance with Computer Science Department policy and RIT policy. I expect you to read and abide by the following policies:
The following are some examples of plagiarism. These are not the only examples of plagiarism.
There are only two exceptions to the prohibition on plagiarism:
