Help with Graduate Classes -- Tutoring in Master in Information Assurance

Hello,

I'm currently enrolled in the Master of Science in Iowa State University. The class that I am taking is the Computer and Network Forensics (Cpr E -Inf As 536). I was wondering if anyone could help me in the class.

Sample assignment:

1: Given a message, M, is m1,m2, ... mn where each mi is 64 bits. Prove that each of the following functions is a bad cryptographic checksum:

1.a: m1+....+mn where addition is 64 bit ignoring the carry bit.

1.b: all mi xored to form one 64 bit number


Thank you in advance,
Sebastian

 

Hello,

I know there a number of people who are taking courses in information assurance, computer science and other engineering areas, but no one seems to want to help.

Is there at least a site that can assist with assignments?

 

Sorry, I can't help you because I am not in the subject. However, check your PM.

 

It is not that nobody wants to help you. The textbook should have at least briefly covered some of this material.
