In professional audio and telecommunications, attack time is the time between the instant that a signal at the input of a device or circuit exceeds the activation threshold of the device or circuit and the instant that the device or circuit reacts in a specified manner, or to a specified degree, to the input. [1]
Delta time or delta timing is a concept used amongst programmers in relation to hardware and network responsiveness. [1] In graphics programming, the term is usually used for variably updating scenery based on the elapsed time since the game last updated, [2] (i.e. the previous "frame") which will vary depending on the speed of the computer, and how much work needs to be done in the program at ...
The graph on the left denotes a case where the timing attack is successfully able to detect a cached image whereas the one on the right is unable to do the same. In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms ...
In telecommunications, attack-time delay is the time needed for a receiver or transmitter to respond to an incoming signal.. For a receiver, the attack-time delay is defined as the time interval from the instant a step radio-frequency signal, at a level equal to the receiver's threshold of sensitivity, is applied to the receiver input, to the instant when the receiver's output amplitude ...
Frame-bursting is a communication protocol feature used at the link layer in communication networks to alter the transmission characteristics in order to benefit from higher throughput. It is a technique sometimes used in communication protocols for shared mediums to achieve higher throughput by allowing the transmitter to send a series of ...
Consequently, this attack remains vulnerable if unprotected against certain time-memory tradeoffs such as developing rainbow tables to target multiple instances of the enhanced key space in parallel (effectively a shortcut to repeating the algorithm). For this reason, key stretching is often combined with salting. [1]
According to the 802.11 standards, a delivery traffic indication message (DTIM) period value is a number that determines how often a beacon frame includes a DTIM, and this number is included in each beacon frame. A DTIM is included in beacon frames, according to the DTIM period, to indicate to the client devices whether the access point has ...
IEEE 802.11 RTS/CTS (request to send/clear to send) is the optional mechanism used by the 802.11 wireless networking protocol to reduce frame collisions introduced by the hidden node problem. Originally the protocol fixed the exposed node problem as well, but later RTS/CTS does not, but includes ACKs.
