Computer networks are inherently insecure. To keep information secret, it must be encrypted. Encryption protocols fall into two general classes: secret key (e.g. DES, IDEA), and public key (e.g. RSA). Using these protocols is straight-forward; the hard part is key management. In addition to providing secrecy, cryptographic protocols can also provide authentication. Finally, cryptography can [...]
