In cryptography, rekeying refers to the process of changing the session key—the encryption key of an ongoing communication—in order to limit the amount of data encrypted with the same key.
SmartKey was the first macro processing program of its type, and the first terminate-and-stay-resident program for PCs and CP/M microcomputers, their eight bit predecessors. [ 1 ] Smartkey's "keyboard definitions" were first used with the early word processing program WordStar to change margins of screenplays .
The security of their production, transport, storage, distribution, accounting, employment, and finally destruction required thousands of trusted agents, world-wide.

A standard pin kit offers the exact size variety needed. Using manufacturer depths permits easy keying, but often you must deviate slightly for optimum accuracy. Pin kits provide master- wafers, top- pins, and springs for a thorough cylinder rebuild. Replace any worn parts, rekey, lubricate, and reassemble.
There are potential weaknesses in the implementation of the protocol between the dongle and the copy-controlled software. For example, a simple implementation might define a function to check for the dongle's presence, returning "true" or "false" accordingly, but the dongle requirement can be easily circumvented by modifying the software to always answer "true".
The Electronic Key Management System (EKMS) is a United States National Security Agency led program responsible for Communications Security key management, accounting, and distribution. Specifically, EKMS generates and distributes electronic key material for all NSA encryption systems whose keys are loaded using standard fill devices, and ...
A security concern with any remote entry system is a spoofing technique called a replay attack, in which a thief records the signal sent by the key fob using a specialized receiver called a code grabber, and later replays it to open the door.
