1 session key
The key used for encrypting data during a communication session. -
2 Key Distribution Center
A network service that supplies session tickets and temporary session keys to users and computers within an Active Directory domain. The KDC runs on each domain controller as part of Active Directory Domain Services (AD DS). -
3 master key
"The key used by the client and server for all session key generation. The master key is used to generate the client-read key, the client-write key, the server-read key, and the server-write key. Master keys can be exported as simple key BLOBs." -
4 private key
"The secret half of a cryptographic key pair that is used with a public key algorithm. Private keys are typically used to decrypt a symmetric session key, digitally sign data, or decrypt data that has been encrypted with the corresponding public key." -
5 public key
"The nonsecret half of a cryptographic key pair that is used with a public key algorithm. Public keys are typically used when encrypting a session key, verifying a digital signature, or encrypting data that can be decrypted with the corresponding private key." -
6 public key algorithm
"An asymmetric cipher that uses two keys, one for encryption, the public key, and the other for decryption, the private key. As implied by the key names, the public key used to encode plaintext can be made available to anyone. However, the private key must remain secret. Only the private key can decrypt the ciphertext. The public key algorithm used in this process is slow (on the order of 1,000 times slower than symmetric algorithms), and is typically used to encrypt session keys or digitally sign a message." -
7 authenticator
"A data structure used by one party to prove that another party knows a secret key. In the Kerberos authentication protocol, authenticators include timestamps, to prevent replay attacks, and are encrypted with the session key issued by the Key Distribution Center (KDC)."مصدّق -
8 hash algorithm
"An algorithm that produces a hash value of some piece of data, such as a message or session key. With a good hash algorithm, changes in the input data can change every bit in the resulting hash value; for this reason, hashes are useful in detecting any modification in a data object, such as a message. Furthermore, a good hash algorithm makes it computationally infeasible to construct two independent inputs that have the same hash. Typical hash algorithms include MD2, MD4, MD5, and SHA-1." -
9 hash function
"An algorithm that produces a hash value of some piece of data, such as a message or session key. With a good hash algorithm, changes in the input data can change every bit in the resulting hash value; for this reason, hashes are useful in detecting any modification in a data object, such as a message. Furthermore, a good hash algorithm makes it computationally infeasible to construct two independent inputs that have the same hash. Typical hash algorithms include MD2, MD4, MD5, and SHA-1."
