Kalit va elektron raqamli imzo.
 

Elektron raqamli imzo
- elektron hujjatga biriktirilgan va mazkur elektron hujjat 
axborotini elektron raqamli imzoning yopiq kalitidan foydalangan holda maxsus 
o’zgartirish natijasida hosil qilingan hamda elektron raqamli imzoning ochiq kaliti 
yordamida elektron hujjatdagi axborotda xatolik yo’qligini aniqlash va elektron 
raqamli imzo yopiq kalitining egasini identifikatsiya qilish imkoniyatini beradigan 
imzo; 

Elektron raqamli imzoning yopiq kaliti
- elektron raqamli imzo vositalaridan 
foydalangan holda xosil qilingan, faqat imzo qo’yuvchi shaxsning o’ziga ma’lum 
bo’lgan va elektron hujjatda elektron raqamli imzoni yaratish uchun mo’ljallangan 
belgilar ketma-ketligi; 

Elektron raqamli imzoning ochiq kaliti
- elektron raqamli imzo vositalaridan 
foydalangan holda hosil qilingan, elektron raqamli imzoning yopiq kalitiga mos 
keluvchi, axborot tizimining har qanday foydalanuvchisi foydalana oladigan va 


19 
elektron hujjatdagi elektron raqamli imzoning haqiqiyligini tasdiqlash uchun 
mo’ljallangan belgilar ketma-ketligi; 

Elektron raqamli imzoning haqiqiyligini tasdiqlash
- elektron raqamli imzoning 
elektron raqamli imzo yopiq kalitining egasiga tegishliligi va elektron hujjatdagi 
axborotda xatolik yo’qligi tekshirilgandagi ijobiy natijani beradi. 
Introduction to information technology in technical systems.
 
Information 
technology (IT)
is 
the 
application 
of computers  
and telecommunications 
equipment to 
store, 
retrieve, 
transmit 
and 
manipulate data, often in the context of a business or other enterprise. 
The term is commonly used as a synonym for computers and computer 
networks, but it also encompasses other information distribution technologies such 
as television and telephones. Several industries are associated with information 
technology, including computer hardware, software,  elektronics,  semiconductors,
internet,  telecommunications equipment, engineering, healthcare, e-commerce and 
computer services.
Humans have been storing, retrieving, manipulating and communicating 
information since the Sumerians developed writing in about 3000 BC, but the 
term 
information technology
in its modern sense first appeared in a 1958 article 
published in the 
Harvard Business Review
; authors Harold J. Leavitt and Thomas 
L.Whisler commented that "the new technology does not yet have a single 
established name. We shall call it information technology (IT)." Their definition 
consists of three categories: techniques for processing, the application of statistical 
and mathematical methods to decision-making, and the simulation of higher-order 
thinking through computer programs.
Robotics i

an interdisciplinary branch 
of engineering and science that 
includes mechanical 
engineering, elektronic 
engineering, information 
engineering, computer science, and others. Robotics deals with the design, 
construction, operation, and use of robots, as well as computer systems for their 
control, sensory feedback, and information processing.

Data transmission
refers to the process of transferring data between two or 
more digital devices. Data is transmitted from one device to another in analog or 
digital format. Basically, data transmission enables devices or components within 
devices to speak to each other. 
 
Data transmission (also data communication or digital communications) is 
the transfer of data (a digital bitstream or a digitized analog signal) over a point-to-
point or point-to-multipoint communication channel. Examples of such channels 
are copper 
wires, optical 
fibers, wireless communication 
channels, storage 
media and computer buses. The data are represented as an electromagnetic signal, 
such as an electrical voltage, radiowave, microwave, or infrared signal. 
An elektronic signature, or e-signature
, refers to data in elektronic form, which is 
logically associated with other data in elektronic form and which is used by 
the signatory to sign. This type of signature provides the same legal standing as a 
handwritten signature as long as it adheres to the requirements of the specific 
regulation it was created under (e.g., eIDAS in the European Union, NIST-DSS in 
the USA or ZertES in Switzerland).  
Elektronic signatures are a legal concept distinct from digital signatures, a 
cryptographic mechanism often used to implement elektronic signatures. While an 
elektronic signature can be as simple as a name entered in an elektronic 
document, digital signatures are increasingly used in e-commerce and in regulatory 
filings to implement elektronic signatures in a cryptographically protected way. 
Standardization 
agencies 
like NIST or ETSI provide 
standards 
for 
their 
implementation (e.g., NIST-DSS, XAdES or PAdES). The concept itself is not 


21 
new, with common law jurisdictions having recognized telegraph signatures as far 
back as the mid-19th century and faxed signatures since the 1980s.
