Supplemental access control (SAC) is a set of security features defined by ICAO [1] for protecting data contained in electronic travel documents (e.g. electronic passports). SAC specifies the Password Authenticated Connection Establishment (PACE) protocol, which itself supplements and improves upon the Basic Access Control (BAC) protocol also ...
ICAO: Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.
The International Civil Aviation Organization Public Key Directory (ICAO PKD) is a database maintained by the International Civil Aviation Organization holding national cryptographic keys related to the authentication of e-passport information. The ICAO PKD content is open to the public, and can be downloaded for free at https://download.pkd ...
EAC was introduced by ICAO [3] [4] as an optional security feature (additional to Basic Access Control) for restricting access to sensitive biometric data in an electronic MRTD. A general idea is given: the chip must contain chip-individual keys, must have processing capabilities and additional key management will be required.
The fixed format allows specification of document type, name, document number, nationality, date of birth, sex, and document expiration date. All these fields are required on a passport. There is room for optional, often country-dependent, supplementary information. There are also two sizes of machine-readable visas similarly defined.
These capabilities can also be considered in context of the ICAO SWIM-concept (Doc 10039, Manual on System Wide Information Management (SWIM) Concept). [ 2 ] Eurocontrol initially presented the SWIM System concept to the Federal Aviation Administration (FAA) in 1997 and in 2005, the ICAO Global ATM Operational Concept adopted the SWIM concept ...
The ICAO format has already been in use for all domestic flight plans in Canada, Mexico and many other countries for a number of years. Regardless of the form used, air traffic controllers (ATC) issue clearances based on filed equipment codes, therefore it is important for pilots to use the appropriate coding.
[5] [6] The ICAO 24-bit address can be represented in three digital formats: hexadecimal, octal, and binary. These addresses are used to provide a unique identity normally allocated to an individual aircraft or registration. As an example, following is the ICAO 24-bit address assigned to the Shuttle Carrier Aircraft with the registration N905NA ...
