This crucial work doesn’t happen without support from the community. The quick and dirty: OpenSSL version 1.1.1 was evaluated with special foci on new TLS…
Bulletproofs are a specific type of range proof based on new cryptography by Benedikt Bunz et al. Bulletproofs are a trustless proofs setup that are substantially smaller than the current Borromean style range proofs that were previously used, which reduces the size of Monero transactions by 80-90%. Monero’s latest network update,…
We have completed the security review of the new Pseudorandom Number Generator (PRNG) for OpenSSL1.1.1. This security review was sponsored by Private Internet Access, ExpressVPN, DuckDuckGo, OpenVPN, and the privacy community. Random number generation is a crucial component in all cryptography, because the “randomness” of numbers is the mechanism that makes secret numbers hard to guess. Problems…
Kudelski Security has done a review of Monero Bulletproofs, a specific type of range proof based on new cryptography by Benedikt Bunz et al. Bulletproofs is a trustless proofs setup that is substantially smaller than the current Borromean style range proofs that are currently used, promising to make Monero transactions 10-20%…
