Since ancient times, message encryption has sparked interest, particularly in the military sphere, ranging from the simple Caesar cipher to the German Enigma machine. As the number and complexity of ciphers increased, so did the interest in decryption, which, in turn, drove the creation of even ...
Cryptography is about making secret communication to make messages secure in the presence of adversaries. By encryption, an original message, called plaintext, is transformed into a coded message, called ciphertext. This transformation is performed before the plaintext is transmitted or stored. The ...
The dynamic nature of the approach significantly boosts the security of the system. The team's experimental results demonstrate that this approach is superior to other experimental lightweight cryptography. The strength of MESP lies in its extensive key space and its superiority in frequency analysis ...

This method uses a joined pair of mathematically related keys — public and private. The public key encrypts messages and is freely available, and the private key decrypts an encrypted message and is kept secret. Asymmetric encryption algorithms, like RSA or Elliptic Curve Cryptography (ECC), pr...
The researchers believe the attack could also be used on other protocols that use the same encryption format, such as Apple's Handoff feature, which transfers data between devices via Bluetooth. OpenPGP encryption (as implemented by GnuPGP) may be vulnerable to similar attacks when used in insta...
in the communications industry, where MACtraditionally means media access control address(MAC address). However, MIC also can be used to refer to message digest,which does not use secret keys in the same manner as a MAC, and cannot offer the same level of security without further encryption....
Cryptographic keys.Anencryption algorithmalters data, and a recipient needs a specific code (or key) to make it readable once more. HMAC relies on a shared sets of secret keys. Hash function.A hash algorithm alters or digests the message once more. HMAC usesgeneric cryptographic hash functions...
In one sense, message authentication codes are kind of like the symmetric key version of digital signatures. (Digital signatures are for use with asymmetric encryption systems only.) When using MACs, the sender and recipient use a single key; with digital signatures, a public-private (asymmetric...
