Cryptography is a term used in computer science to describe secure information and communication techniques that use mathematical concepts and a set of rule-based calculations known as algorithms to transform messages in difficult-to-decipher ways. These deterministic algorithms are used for cryptographic key generation, digital signing, data privacy protection, internet browsing, and confidential communications like credit card transactions and email.

Confidentiality is a key priority when it comes to cryptography. It means that only those with the necessary permissions can access the information transmitted and that this information is safeguarded against unauthorized access at all stages of its lifecycle.
Maintaining the privacy of those whose personal information is stored in enterprise systems necessitates confidentiality. As a result, encryption is the only way to ensure that your data is secure while being stored and transmitted.
Even when the transmission or storage medium has been compromised, the encrypted information is practically useless to unauthorized individuals without the right keys for decryption.

In the security context, integrity refers to the accuracy of information systems and their data.
If a system has integrity, it means that its data is moved and processed in predictable ways. Even when the data is processed, it doesnโt change.
Using hashing algorithms and message digests, cryptography ensures the integrity of data. By providing codes and digital keys to ensure that what is received is genuine and from the intended sender, the receiver is assured that the data received has not been tampered with during transmission.

Cryptography also aids in ensuring the identity of both the sender and receiver, as well as the origin or destination of the informationโthe latter being the most important.
It is much easier for your teams to communicate securely once the source of the information has been identified.
Authentication is only possible via a special key exchange thatโs used by the sender to prove his/her identity. A username and password are typically used, but other methods such as a smart card, retina scan, voice recognition, or fingerprint scan may also be used.

Cryptography also contributes to data availability by ensuring that individuals with the appropriate permissions can use systems and retrieve data in a dependable and timely manner. This ensures the dependability and accessibility of information systems.

Non-repudiation refers to the confirmation of a sent or received message. This principle ensures that the sender cannot deny having sent the data. It employs digital signatures to prevent the sender from disputing the data’s origin. It also ensures that the receiver does not deny receiving the message.

One of the most pressing concerns for businesses competing in today’s business environment is information security. When used correctly, cryptography can help you protect your intellectual property and keep it safe from cyber threats and threat actors.
