This is a list of telecommunications encryption terms. This list is derived in part from the Glossary of Telecommunication Terms published as Federal Standard 1037C . A5/1 – a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard.
The term "end-to-end encryption" originally only meant that the communication is never decrypted during its transport from the sender to the receiver. [9] For example, around 2003, E2EE has been proposed as an additional layer of encryption for GSM [10] or TETRA, [11] in addition to the existing radio encryption protecting the communication between the mobile device and the network infrastructure.
COPACOBANA was the first commercially available solution [12] using fast time-memory trade-off techniques that could be used to attack the popular A5/1 and A5/2 algorithms, used in GSM voice encryption, as well as the Data Encryption Standard (DES). It also enables brute force attacks against GSM eliminating the need of large precomputed lookup ...
RIA (Rock Island Armory) 1911s are derivatives of the US Military G.I. M1911-A1, the standard issue US Service pistol from 1911 to 1985. [3] Most RIA models are targeted at the low-end price point of the 1911 pistol market and are basic entry-level MIL-SPEC versions of the 1911. [4] However, some models offer additional higher-end features.
The Ballester–Molina is a short recoil-operated semi-automatic locked breech pistol. The locking system is a near-identical copy of the Model 1911's, with the swinging lock used to unlock the barrel from the slide. The pistol has a two-stage, single action trigger, but unlike that of the 1911 trigger, it pivots rather than slide.
It consists of three fields, including an 8-bit regional code (RR), a 24-bit manufacturer code, and a 24-bit manufacturer-assigned serial number. The check digit (CD) is not considered part of the MEID. The MEID was created to replace electronic serial numbers (ESNs), whose virgin form was exhausted in November 2008. [1]
A common choice is '6-5-5', meaning that the first 6 hex digits of the KSN indicate the Key Set ID (i.e., which BDK is to be used), the next 5 are the TRSM ID (i.e. a device serial number within the range being initialized via a common BDK), and the last 5 are the transaction counter.
The pistol's components are hand-fitted and are not interchangeable. [3] The last four digits of the weapon's serial number are stamped on the top of the barrel, on the right-side of slide assembly, inside of the beavertail grip safety, on each side of the ambidextrous thumb safety, and on the inside face of the mainspring housing group.
