Angajarea unui a Cryptographer pe platforma Freelancer
Cryptology or Cryptography is derived from a Greek word “krypton” that means hidden secret and “graphein” meaning writing. Cryptography denotes the study of techniques that ensure secure communication, in the presence of third parties. Cryptography is indispensable for protecting all the data stored in your computer by making them obscure to the unintended recipients. Not only does it store information, but it also transmits the data in a particular format so that only the intended recipient can read and process it.
Cryptography is very closely associated with disciplines like Cryptology and Cryptanalysis. It includes various techniques such as microdots that help to hide information which are stored or are in transit. Nowadays, Cryptography mostly involves scrambling plain text or clear text into cipher text through a process called encryption, and again back to its original form through a process called decryption.
The four key objectives of Cryptography include:
1. Confidentiality – so the information cannot be comprehended by anyone other than the party to whom it is intended.
2. Integrity – the data that is in storage or transit between the sender and the recipient cannot be altered in any way, without it being detected.
3. Non-repudiation – neither the sender nor the recipient are in a position to deny at a later stage his/her involvement and intention in the creation and transmission of the data.
4. Authentication – both the sender as well as the recipient are able to confirm each other’s identity along with the origin and destination of the data.
Cryptosystems include all the procedures and the protocols that are designed to meet and fulfil the above mentioned objectives. They include not only mathematical procedures and computer programs but also a considerable part about human behaviour and its regulation too.
Types of Cryptographic Algorithms
Secret key cryptography – a single key is used for both encryption and decryption
Public key cryptography – here separate keys are used for encryption and decryption
Hash functions – here through a mathematical procedure, the information is irreversibly transformed to encrypt information.
A person who specialises in the field of cryptography is a cryptographer. A cryptographer is very much in demand because the ability to store and transfer crucial and sensitive data, safely and securely is quite vital for success in the cut-throat business world.
