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
