cs.CR updates on arXiv.org arxiv.org
This paper presents Adamastor, a new low latency and scalable decentralized
anonymous payment system, which is an extension of Ring Confidential
Transactions (RingCT) that is compatible with consensus algorithms that use
Delegated Proof of Stake (DPoS) as a defense mechanism against Sybil attacks.
Adamastor also includes a new Decoy Selection Algorithm (DSA) that can be of
independent interest, called SimpleDSA, a crucial aspect of protocols that use
ring signatures to anonymize the sender. SimpleDSA offers security against
homogeneity attacks and …
