Notes - Overview of Cryptography and its Applications

The following are notes from Introduction to Cryptography with Coding Theory.

  • Cryptography is used to keep data secure
    • Increased need due to dependency on electronic systems
  • Cryptography is often used interchangeably with cryptology and cryptanalysis
    • Cryptology is technically study of communication over unsecured channels
    • Cryptography is designing systems to make channels secured
    • Cryptanalysis deals with breaking cryptographic systems
  • Coding Theory deals with representing input information symbols by output symbols called code symbols
    • often associated with error correcting codes
