  2. Renewal theory - Wikipedia

    en.wikipedia.org/wiki/Renewal_theory

    The renewal interval determined by the random point t (shown in red) is stochastically larger than the first renewal interval. See also: List of paradoxes § Mathematics A curious feature of renewal processes is that if we wait some predetermined time t and then observe how large the renewal interval containing t is, we should expect it to be ...

  3. Group key - Wikipedia

    en.wikipedia.org/wiki/Group_key

    Typically, group keys are distributed by sending them to individual users, either physically, or encrypted individually for each user using either that user's pre-distributed private key. A common use of group keys is to allow a group of users to decrypt a broadcast message that is intended for that entire group of users, and no one else.

  4. Generalized renewal process - Wikipedia

    en.wikipedia.org/wiki/Generalized_Renewal_Process

    F(t) is the cumulative distribution function (CDF) of the underlying failure time distribution, q is the restoration factor, is the vector of parameters of the underlying failure-time distribution. A closed-form solution to the G-renewal equation is not possible. Also, numerical approximations are difficult to obtain due to the recurrent ...

  6. Double Ratchet Algorithm - Wikipedia

    en.wikipedia.org/wiki/Double_Ratchet_Algorithm

    After an initial key exchange it manages the ongoing renewal and maintenance of short-lived session keys. It combines a cryptographic so-called "ratchet" based on the Diffie–Hellman key exchange (DH) and a ratchet based on a key derivation function (KDF), such as a hash function, and is therefore called a double ratchet.

  7. Transient-key cryptography - Wikipedia

    en.wikipedia.org/wiki/Transient-key_cryptography

    A private key is cross-certified using two other transient-key servers. Through independently operating servers, cross-certification can provide third-party proof of the validity of a time interval chain and irrefutable evidence of consensus on the current time. Transient-key cryptographic systems display high Byzantine fault tolerance. A web ...

  9. IEEE 802.11i-2004 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.11i-2004

    IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys.
