MAC & HMAC Cryptography Tool Final Project untuk mata kuliah Kriptografi dengan tema Message Authentication Code (MAC) dan Hash-based Message Authentication Code (HMAC).

This project is an implementation of a blockchain based transaction system to facilitate the buying of research papers and comics. It makes use of the HMAC protocol to verify the identity of users.

Figure 8 illustrates the differences between HMAC and Secure Hash. Essentially, Secure Hash uses a hashing algorithm, such as SHA-3, to produce a fixed-length hash of the message regardless of the ...

I recently found a security flaw in the Google Keyczar crypto library. The impact was that an attacker could forge signatures for data that was “signed” with the SHA-1 HMAC algorithm (the ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics.

The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works.

Dr. Xiang Xie, Algorithm Scientist at PlatON, talks about the impact of lattice-based cryptography on digital asset platforms.

With consideration of privacy disclosure of consensus-based algorithm in distributed energy management (DEM), this paper proposes a homomorphic cryptography base ...
