International Civil Aviation Organization Public Key Directory
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.icao.int/. Participants The United Nations became the first non-state participant in October 2012, enabling issuing of e-UNLP, the electronic form of the United Nations laissez-passer. In December 2014, ICAO reported the PKD as having 45 participants. In 2015 the German Bundesdruckerei (German Federal Printing Office) won the request for tender of the ICAO to provide the ICAO PKD. In July 2017, ICAO reported the PKD as having 58 participants. As of November 2017, 60 participants were part of the ICAO PKD, with the European Union being the 60th member and at the same time the second non-state participant. As of December 2024, 101 parti ...

Database
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash c ...

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

E-passport
A biometric passport (also known as an electronic passport, e-passport or a digital passport) is a passport that has an embedded electronic microprocessor chip, which contains biometric information that can be used to authenticate the identity of the passport holder. It uses contactless smart card technology, including a microprocessor chip (computer chip) and antenna (for both power to the chip and communication) embedded in the front or back cover, or centre page, of the passport. The passport's critical information is printed on the data page of the passport, repeated on the machine readable lines and stored in the chip. Public key infrastructure (PKI) is used to authenticate the data stored electronically in the passport chip, making it expensive and difficult to forge when all security mechanisms are fully and correctly implemented. Most countries are issuing biometric passports to their citizens. Malaysia was the first country to issue biometric passports in 1998. By the ...

Bundesdruckerei
Bundesdruckerei (, short form: BDr) produces documents and devices for secure identification and offers corresponding services. It is based in the Berlin district of Kreuzberg. In addition to complete passport and ID card systems, the security printing house also offers ID documents, high-security cards, document checking devices, security software and trust center services. Bundesdruckerei also produces banknotes, stamps, visas, vehicle documents, tobacco revenue stamps and electronic publications. It was founded as ''Reichsdruckerei'' ("Reich press") in 1879 and existed under this name until 1945.

Request For Tender
An invitation to tender (ITT, also known as a call for bids or a request for tenders) is a formal, structured procedure for generating competing offers from different potential suppliers or contractors looking to obtain an award of business activity in works, supply, or service contracts, often from companies who have been previously assessed for suitability by means of a supplier questionnaire (SQ) or pre-qualification questionnaire (PQQ). Unlike a request for proposal (RFP), which is used when a company sources for business proposals, ITTs are used when a government or company does not require the submission of an original business proposal and is looking solely to award a contract based on the best tender submitted. As a result, whereas ITTs are often decided based on the best price offered, decisions on RFPs may also involve other considerations such as technology and innovation. Both are forms of reverse auction. At the same time, variants may be requested in an ITT, whic ...

Passenger Name Record
A passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that contains the itinerary for a passenger or a group of passengers travelling together. The concept of a PNR was first introduced by airlines that needed to exchange reservation information in case passengers required flights of multiple airlines to reach their destination ("interlining"). For this purpose, IATA and ATA have defined standards for interline messaging of PNR and other data through the "ATA/IATA Reservations Interline Message Procedures - Passenger" (AIRIMP). There is no general industry standard for the layout and content of a PNR. In practice, each CRS or hosting system has its own proprietary standards, although common industry needs, including the need to map PNR data easily to AIRIMP messages, has resulted in many general similarities in data content and format between all of the major systems. When a passenger books an itinerary, the travel agent or travel websit ...

Passport
A passport is an official travel document issued by a government that certifies a person's identity and nationality for international travel. A passport allows its bearer to enter and temporarily reside in a foreign country, access local aid and protection, and obtain consular assistance from their government. In addition to facilitating travel, passports are a key mechanism for border security and regulating migration; they may also serve as official identification for various domestic purposes. State-issued travel documents have existed in some form since antiquity; the modern passport was universally adopted and standardized in 1920. The passport takes the form of a booklet bearing the official name and emblem of the issuing government and containing the biographical information of the individual, including their full name, photograph, place and date of birth, and signature. A passport does not create any rights in the country being visited nor impose any obligation o ...
