Having more students in the classroom
What aspect of cryptographic attacks do attackers typically focus on when attempting to access encrypted data?
Implementation vulnerabilities
What is a 'hash collision' in the digital world?
When two different plain texts create exactly the same hash
How can hash collisions be prevented?
By increasing the size of the hash
Why are collisions considered bad in hashing?
Hashes are always supposed to be unique
Which hashing algorithm experienced a well-known collision issue in 1996?
MD5 (Message Digest Algorithm version 5)
What type of attack involves downgrading encryption during communication?
Downgrade attack
What encryption mechanism was succeeded by Transport Layer Security (TLS)?
