Explain why a checksum or CRC, by itself, does not provide security.
Homework Answers
CRC or checksum doesn't provide security by itself, because CRC
is can be easily reversible(since it is cryptographically weak
algorithm), so data can be accessed/modified by attacker,
it only works effectively for common communication channel errors,
so, to stop attacker, we need to apply strong encryption algorithm
on CRC

Data Commincations: Error Detection and Correction Help understanding Excerpt: Text reads: "The Internet checksum provides greater error-detection capability than a parity bit or two-dimensional parity scheme but is considerably less effective than the cyclic redundancy check (CRC), discussed next. The primary reason for its adoption in Internet protocols is efficiency. Most of these protocols are implemented in software and the Internet checksum, involving simple addition and comparison operations, causes very little overhead. It is assumed that at the lower link...

A data stream sent over Ethernet is divided up into frames of up to 1,500 bytes each. Each frame is terminated by a 32-bit checksum calculated using a hashing algorithm called the cyclic redundancy check (CRC). Show that there must be at least two frames (somewhere, sometime) that have the same CRC checksum. This is an "essay" question. Write a an argument of a paragraph or so. Imagine you are trying to explain this to another computer science student who...
