Talk:Adventist Youth Honors Answer Book/Regional/Cryptology

This looks like a cool honor. If the NAD decides to adopt it (or maybe have an advanced version) I think it should touch on these topics:

• symmetric/asymmetric cryptography keys
  • A symmetric key uses a single key to both encrypt and decrypt. Also called a shared key.
  • An asymmetric key system uses one key to encrypt and a different one to decrypt. Once a message is encrypted, the encryption key cannot be used to decrypt it.
• public/private keys
  • A form of asymmetric keys where one key is secret and the other is public. The public key is used to encrypted a message that only the holder of the private key can decrypt.
• Crypto signatures
  • A message can be signed to show that it was generated by the entity holding the private key by using the private key to encode a message that anyone can decrypt using the public key.

• Diffie Hilman exchange
  • A way for two parties to create a secret shared key by combining their private keys without exchanging their private keys. It's pretty cool, but hard to explain in one sentence.
