Part 2: Digital Hash
Perhaps the single most interesting item in court trial proceedings is the veracity of evidence. A hash function satisfies this issue completely. Analyze the concept of a digital hash function.
1) What is digital hash?
SOME THOUGHTS: Define a hash value. Compare has to CRC. Use mathematics to prove that files have not changed since the point of seizure. [Min 100 words.]
2) What is a digital signature?
SOME THOUGHTS: Proves that (because of the hash function) that a file has not changed … preserves data integrity … provides identity … provides nonrepudiation. [Min 100 words.]
3) How is a hash function related to a digital signature?
SOME THOUGHTS: Hash values are smaller that original data but is directly to that data. Signing the hash value produces the same data integrity check as signing the original data. [Min 100 words.]
