Initially, only the RC4 encryption algorithm was supported with keys of only 40 bits because of export restrictions on cryptography at that time , but the key length was extended up to bits in … encryption algorithm. The Data Encryption Standard or DES was, and probably still is, one of the more well-known algorithms of the modern cryptographic era.

Thanksgiving Holiday. Nov 25 No class! Optional: Daily Show clip , 60 Minutes clip. Pfleeger, Shari Lawrence Pfleeger, 3rd ed. We will also provide lecture notes for most of the lectures. It provides extra reading and background. Note that you should not view the availability of lecture notes as a substitute for attending class: our discussion in class may deviate somewhat from the written material, and you should take your own notes as well.

Projects will be done in groups. The mechanics of project groups will be announced later in the semester. For homeworks, you must always write up the solutions on your own. Similarly, you may use references to help solve homework problems, but you must write up the solution on your own and cite your sources. You may not share written work or programs with anyone else. You may not receive help on homework assignments from students who have taken the course in previous years, and you may not review homework solutions from previous years.

In writing up your homework you are allowed to consult the instructors, TAs, assigned texts, posted notes, and any materials cited by them. If you do so, you are required to cite your source s. Simply copying an answer is not sufficient; you are expected to write it up in your own words, and you must be able to explain it if you are asked to do so.

Your answers may refer to course material and to homeworks from earlier in the semester. You are not permitted to consult others in the class; you are not permitted to "Google for the answer" to homework questions. Copying solutions or code, in whole or in part, from other students or any other source without acknowledgment constitutes cheating. Any student found to be cheating in this class will automatically receive an F grade and will also be referred to the Office of Student Conduct.

You should never read another student's solution or partial solution, nor have it in your possession, either electronically or on paper. You should write your homework solution strictly by yourself. Presenting another person's work as your own constitutes cheating, whether that person is a friend, an unknown student in this class or a previous semester's class, a solution set from.

Presenting another person's work as your own constitutes cheating, whether that person is a friend, an unknown student in this class or a previous semester's class, a solution set from a previous semester of this course, or an anonymous person on the Web who happens to have solved the problem you've been asked to solve.

Everything you turn in must be your own doing, and it is your responsibility to make it clear to the graders that it really is your own work. The following activities are specifically forbidden in all graded course work: Possession or theft of another student's solution or partial solution in any form electronic, handwritten, or printed.

Giving a solution or partial solution to another student, even with the explicit understanding that it will not be copied. Working together with anyone else to develop a solution that is subsequently turned in either by you or by the other person. Looking up solution sets from previous semesters and presenting that solution, or any part of it, as your own. Academic dishonesty has no place in a university; it wastes our time and yours, and it is unfair to the majority of students. In our experience, nobody begins the semester with the intention of cheating.

Students who cheat do so because they fall behind gradually and then panic. Some students get into this situation because they are afraid of an unpleasant conversation with a professor if they admit to not understanding something. We would much rather deal with your misunderstanding early than deal with its consequences later. Even if you are convinced that you are the only person in the class that doesn't understand the material, and that it is entirely your fault for having fallen behind, please overcome your feeling of guilt and ask for help as soon as you need it.

Remember that the other students in the class are working under similar constraints--they are taking multiple classes and are often holding down outside employment. Don't hesitate to ask us for help--helping you learn the material is what we're paid to do, after all! Warning From time to time, we may discuss vulnerabilities in widely-deployed computer systems.

This is not intended as an invitation to go exploit those vulnerabilities. It is important that we be able to discuss real-world experience candidly; students are expected to behave responsibly.

Berkeley policy is very clear: you may not break into machines that are not your own; you may not attempt to attack or subvert system security. Breaking into other people's systems is inappropriate, and the existence of a security hole is no excuse. Unethical or inappropriate actions may result in failing the course and being referred for further discipline.

Contact information If you have a question, your best option is to post a message to the ucb. The staff instructor and TAs will check the newsgroup regularly. When using the newsgroup, please do not post answers to homework questions before the homework is due. If your question is personal or not of interest to other students, you may send email to cs cory.

Email to cs cory is forwarded to the instructor and all TAs. If you wish to talk with one of us individually, you are welcome to come to our office hours. If the office hours are not convenient, you may make an appointment with any of us by email.

The instructor and TAs may post announcements, clarifications, etc. Hence you should read the newsgroup regularly whether you post questions to it or not. If you've never done this before, there is online information about how to access UCB newsgroups see also here for more. Mail inquiries to cs cory. Notes [ps] [pdf]. Optional: Wired news article.

Since that time, this paper has taken on a life of its own Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between literally billions of people and is used as a tool for commerce, social interaction, and the exchange of an increasing amount of personal information, security has become a tremendously important issue for every user to deal with.

Modern cryptography exists at the intersection of the disciplines of mathematics , computer science , electrical engineering , communication science , and physics. Applications of cryptography include electronic commerce , chip-based payment cards , digital currencies , computer passwords , and military communications. Cryptography prior to the modern age was effectively synonymous with encryption , converting information from a readable state to unintelligible nonsense. The sender of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice "A" for the sender, Bob "B" for the intended recipient, and Eve " eavesdropper " for the adversary.

The seminar will cover ten topics in computer security and cryptography: one idea per week. The course is mostly self contained, but some knowledge of programming and mathematical maturity will be very helpful. The course will cover one topic idea per week. Please keep in mind that there are many more ideas in computer security that we will not get to in this seminar. Students are encouraged to take the more advanced security courses in their junior and senior years.

    Alan Konheim knows all about this because he worked for IBM when it was a leader in the field of cryptology and because he has kept up with new developments.
