Neuro-Inspired Algorithms to Enhance Cryptography

Cryptography

The practice and study of methods for protecting data and communication against unauthorised access is known as cryptography.

Cryptography is a branch of study and application that deals with data security and communication by using encoding methods to make sure that only people with the proper authorization can access and understand the data. Ensuring the confidentiality, integrity, and authenticity of data and messages is crucial for a variety of applications, including safe online communication and data protection.

Here are the components of cryptography:

Components of cryptographic system

• •

  Plain Text: It is imperative to ensure the protection of data during the process of transmission.

• •

  Encryption Algorithm: The process of converting a given plaintext and encryption key into a ciphertext can be achieved through the utilisation of a mathematical approach known as an encryption algorithm. The cryptographic method generates ciphertext by utilising an encryption key and plaintext as input.

• •

  Ciphertext: The ciphertext refers to the transformed version of the plaintext that is generated via the utilisation of an encryption method and a specific encryption key. The security measures implemented for the encrypted text are insufficient. It exhibits a continuous movement through a publicly accessible conduit. The interception or compromising of a communication channel is possible for any individual who possesses access to it.

• •

  Decryption Algorithm: The decryption algorithm is a mathematical technique that, when provided with a ciphertext and decryption key, produces a unique plaintext. The cryptographic technique in question can produce plaintext by utilising a decryption key and an input of ciphertext. The decryption algorithm and the encryption algorithm are intimately interconnected due to their inherent reversal of operations.

• •

  Encryption Key: The encryption key is known to the sender. To derive the ciphertext, the sender inputs both the encryption key and the plaintext into the encryption process.

• •

  Decryption Key: The decryption key is a value that is known to the recipient. While the decryption key and the encryption key may not be identical, they are intrinsically linked. To determine the original plaintext, the recipient inputs the encrypted message, known as the ciphertext, together with the decryption key into the decryption algorithm.
