Abstract: Computing Modular multiplicative inverse is an important step in many arithmetic algorithms used in Cryptography. For example, Montgomery modular multiplication [2] is required to find out ...

There might be an opportunity to consolidate. AFAIK, Fermat plus addition chain should be fastest. For our fixed parameter P256 implementation, we invert either modulo p or n. We already have a fixed ...

According to DeepLearning.AI, the newly launched course 'DSPy: Build and Optimize Agentic Apps' offers a comprehensive introduction to DSPy's signature and module-based programming model, enabling ...

I started the bitcoin_math project in order to teach myself the basics of Bitcoin math from first principles, without having to wade through the source code of any of the crypto or "bignum" libraries ...

ABSTRACT: This paper considers a decomposition framework as a mechanism for information hiding for secure communication via open network channels. Two varieties of this framework are provided: one is ...

ABSTRACT: Numerous cryptographic algorithms (ElGamal, Rabin, RSA, NTRU etc) require multiple computations of modulo multiplicative inverses. This paper describes and validates a new algorithm, called ...
