Foundations of Cryptography and Digital Trust

Which of the following factors determines the strength of encryption?

  • A Character-set encoding
  • B Length of the key
  • C Operating system
  • D Ease of use
Explanation

Key length determines the size of the possible keyspace. A longer key generally requires substantially more computational effort to guess through brute force, increasing encryption strength.
