   • encryption key
     • key to locked door

2. frequency analysis

   • how often word come and way to get code

3. computationaly hard

   • hard for a copmuter to crack

   • diffrent keys are used to encrypt and decrypt

5. public key criptogrophy

   • is any cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner.

6. big data

   • Big data is data sets that are so voluminous and complex that traditional data processing application software are inadequate to deal with them.
