Meaning of Data Encryption And Purpose

Hi

Data encryption refers to the process of encoding data in such a way that only the person who encodes it knows the decoded message and also the person who has the logic of how to decode it. The aim of data encryption if to prevent theft of personal data and information. Data encryption helps in data security as the intruder doesn’t know the decoding process and the encoded data appears meaningless to him thus preventing intruders from thieving personal data or any important government information.

Meaning of Data Encryption And Purpose

Data encryption or encryption is the conversion of data or electronic data into another form called “ciphertext”. When the data is encryption, it cannot be understood easily by anyone except for authorized parties or the owner itself. The main objective of encryption is to keep the confidentiality or privacy of digital data transmitted over the internet or other computer networks or stored on computer systems.

Modern encryption algorithms play an important role in the security assurance of IT systems and communications because they not only offer privacy but the following key elements of security as well:

• * Authentication – the origin or source of the message can be validated.
• * Integrity – the contents of a message can be verified if it has been tempered since it was sent.
• * Non-repudiation – the sender of a message cannot deny that he is the one who sent the message.

The word “encryption” originated from the Greek word “kryptos” which means secret or hidden. The use of encryption is almost as old as the art of communication itself. As early as 1900 BC, Egyptian scribes use non-standard or unusual hieroglyphs to conceal the meaning of an inscription.
