Encryption and decryption are the essential processes in multimedia processing. Especially, in digital image processing, the importance of these two is high. Digital image processing facing ...

This paper presents a design of data encryption and decryption in a network environment using RSA algorithm with a specific message block size.

Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

Types of asymmetric encryption include RSA and PKI. RSA is a popular algorithm used to encrypt data with a public key and decrypt it with a private key for secure data transmission.

Column encryption in ASE uses Advanced Encryption Standard (AES) with 128, 192 or 256-bit encryption key sizes. The longer the bit string, the more difficult it is for a hacker to decrypt. On the ...

Some cryptographers are looking for RSA replacements because the algorithm is just one encryption algorithm that may be vulnerable to new machines that exploit quantum effects in electronics.

Symmetric encryption requires that the sender and receiver both use the same algorithm and the same encryption key. Decryption is simply the reverse of the encryption process — hence the ...

The four selected encryption algorithms will become part of NIST's post-quantum cryptographic standard, expected to be finalized around 2024. This selection marks the beginning of NIST's post ...
