In this thesis we propose a new family of practical and secure mental poker protocols, which are efficient enough to achieve real-time performance to security play Texas Hold-em over the Internet, for up to ten players, using personal computers.

In this paper we propose new decentralized digital signature protocols to allow massive bulk verifications (MAVE). The protocols satisfies very tight requirements of performance and storage. MAVE requires a third party with no special trust and a broadcast medium. MAVE can be used for groups of millions of users or autonomous agents that generate thousands of signatures per second that must...more

In this paper we propose a new payment scheme based on the MAVE digital signature protocol, for use in peer to peer currency networks based on a block chain. The proposed payment scheme requires less resources for the users than Bitcoin and can be used to create a truly lightweight peer to peer currency network that stands 700 payments/second, and 5 million new user accounts/year, on an...more

Disclosure of a security vulnerability found in BouncyCastle ECDSA signature verification code that, in applications that must verify other people's signatures, can result in remote application terminations and DoS attack. If affects Bitcoin nodes coded in Java/C# that uses the Bouncycastle cryptographic library.
