English

This article introduces a method of hiding transaction amounts in the strongly decentralized anonymous cryptocurrency Monero. Similar to Bitcoin, Monero is a cryptocurrency which is distributed through a proof of work “mining” process. The original Monero protocol was based on CryptoNote, which uses ring signatures and one-time keys to hide the destination and origin of transactions. Recently the technique of using a commitment scheme to hide the amount of a transaction has been discussed and implemented by Bitcoin Core Developer Gregory Maxwell. In this article, a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature is described which allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation. Some extensions of the protocol are provided, such as Aggregate Schnorr Range Proofs, and Ring Multisignature. The author would like to note that early drafts of this were publicized in the Monero Community and on the bitcoin research irc channel. Blockchain hashed drafts are available in [14] showing that this work was started in Summer 2015, and completed in early October 2015. An eprint is also available at http://eprint.iacr.org/2015/1098.

research-lab->mrl3_abstract	Recently, there have been some vague fears about the CryptoNote source code and protocol floating around the internet based on the fact that it is a more complicated protocol than, for instance, Bitcoin. The purpose of this note is to try and clear up some misconceptions, and hopefully remove some of the mystery surrounding Monero Ring Signatures. I will start by comparing the mathematics involved in CryptoNote ring signatures (as described in [CN]) to the mathematics in [FS], on which CryptoNote is based. After this, I will compare the mathematics of the ring signature to what is actually in the CryptoNote codebase.	مؤخراً كان هناك بعض المخاوف المنتشره عبر الإنترنت حول بروتوكول كريبتونوت (CryptoNote) قائمه علي حقيقه أنه أكثر تعقيداً من علي سبيل المثال بروتوكول البيتكوين ( Bitcoin). الغرض من هذا البحث تصحيح بعض المفاهيم الخاطئه و أملاً في إزاله الغموض المحيط بنظام توقعيات-الطوق (Ring-Signatures) الخاصه بمونيرو. سوف أبدأ بمقارنه الرياضيات المشاركه في توقيعات-طوق الخاصه بكريبتونوت( CryptoNote) (كماتم وصفها في البرتوكول) إلي الرياضيات في [FS] التي بُني عليها البروتوكول. بعد ذلك سأقوم بمقارنه الرياضيات في نظام توقيعات-الطوق لما هو موجود بالفعل في كود مصدر كريبتونوت (CryptoNote) .
research-lab->mrl4	Improving Obfuscation in the CryptoNote Protocol	تحسين التعتيم في بروتوكول كريبتونوت (CryptoNote)
research-lab->mrl4_abstract	We identify several blockchain analysis attacks available to degrade the untraceability of the CryptoNote 2.0 protocol. We analyze possible solutions, discuss the relative merits and drawbacks to those solutions, and recommend improvements to the Monero protocol that will hopefully provide long-term resistance of the cryptocurrency against blockchain analysis. Our recommended improvements to Monero include a protocol-level network-wide minimum mix-in policy of n = 2 foreign outputs per ring signature, a protocol-level increase of this value to n = 4 after two years, and a wallet-level default value of n = 4 in the interim. We also recommend a torrent-style method of sending Monero output. We also discuss a non-uniform, age-dependent mix-in selection method to mitigate the other forms of blockchain analysis identified herein, but we make no formal recommendations on implementation for a variety of reasons. The ramifications following these improvements are also discussed in some detail. This research bulletin has not undergone peer review, and reflects only the results of internal investigation.	قد حددنا العديد من هجمات التحليل المتاحه ضد بروتوكول كريبتونوت (CryptoNote 2.0) التي تهدف إضعاف عدم إمكانيه التتبع.نقوم بتحليل الحلول الممكنه, ومناقشه مزاياها وعيوبها, ونوصي بالتحسينات اللازمه لبروتوكول مونيرو التي ستقوم بمقاومه تتبع سلسله الكتل علي المدي الطويل. تشمل هذه التحسينات علي مستوي البروتوكول والشبكه أقل عدد لدمج توقيعات-الطوق (n = 2) , علي مستوي البروتوكول رفع هذه القيمه بعد سنتين إلي ( n = 4 ) , وعلي مستوي المحفظه (n = 4) في هذه الأثناء. ننصح أيضاً بنظام الند إلي الند في إرسال مخرجات معامله مونيرو. نناقش أيضاً طريقه إختيار غير موحده تعتمد علي العمر للتخفيف من هجمات تحليل سلسله الكتل الذي تم تحديده هنا. ولكننا لا نقدم أي توصيات رسميه بشأن دمجها لمجموعه متنوعه من الأسباب. ونناقش أيضاً بالتفصيل الأثار المترتبه علي هذه التحسينات. هذا البحث لم يتم مراجعته ولا يعكس سوي نتائج التحقيق الداخلي.

research-lab->mrl6_abstract	Users of the Monero cryptocurrency who wish to reuse wallet addresses in an unlinkable way must maintain separate wallets, which necessitates scanning incoming transactions for each one. We document a new address scheme that allows a user to maintain a single master wallet address and generate an arbitrary number of unlinkable subaddresses. Each transaction needs to be scanned only once to determine if it is destinated for any of the user’s subaddresses. The scheme additionally supports multiple outputs to other subaddresses, and is as efficient as traditional wallet transactions.
