Computer verification of security authentication of a user accessing a network. Passwords, digital certificates, smart cards and biometrics can be used to detect the identity of the network. Computer security authentication involves verifying the integrity of the e-mail authentication and MAC (Message Authentication Code), the revision of the integrity of the message transmitted. There are people of authentication, challenge-response authentication, passwords,Digital signature, IP spoofing and biometrics.

Human authentication is to verify that a person who initiated the computer transaction, not the. challenge-response authentication is an authentication method used to prove the identity of a user accessing the network. When a user logs on, the Network Access Server (NAS), wireless access point or authentication server creates a challenge, usually a random number to the client computer. The client software uses the passwordencrypt the challenge of an encryption algorithm or a one-way hash function and sends the result back to the network. This is the answer.
