Webbthe SM9 algorithm for supporting the underlying cryptography. And group signature, ring signature and two-party signature are introduced in succession to design the related … SM9 is a Chinese national cryptography standard for Identity Based Cryptography issued by the Chinese State Cryptographic Authority in March 2016. It is represented by the Chinese National Cryptography Standard (Guomi), GM/T 0044-2016 SM9. The standard contains the following components: (GM/T 0044.1) The … Visa mer Identity Based Cryptography is a type of public key cryptography that uses a widely known representation of an entity's Identity (name, email address, phone number etc.) as the entities public key. This eliminates the … Visa mer The Identity Based Key Encapsulation Algorithm in SM9 traces its origins to a 2003 paper by Sakai and Kasahara titled "ID Based Cryptosystems with Pairing on Elliptic Curve." It was standardized in IEEE 1363.3, in ISO/IEC 18033-5:2015 and IETF RFC 6508. Visa mer An open source implementation of the SM9 algorithms is part of the GMSSL package available on GitHub. The Shenzhen Aolian Information Security Technology Co (also known as Olym Tech) is also marketing a series of products that implement the SM9 … Visa mer The SM9 Standard adopted in 2016 is one of a number of Chinese national cryptography standards. Other publicly available Chinese cryptographic standards are: Visa mer The Identity Based Signature Algorithm in SM9 traces its origins to an Identity Based Signature Algorithm published at Asiacrypt 2005 in the paper: … Visa mer The Identity Based Key Agreement algorithm in SM9 traces its origins to a 2004 paper by McCullagh and Barreto titled, "A New Two-Party Identity-Based Authenticated Key Agreement" [1]. The International Standards Organization incorporated this … Visa mer The following links provide more detailed information on the SM9 algorithms in English: • Visa mer
基于SM9算法的部分盲签名方案_参考网
Webb文献 [ 15 ]提出的基于SM9算法的盲签名方案分为消息盲化、签名生成和签名验证3个步骤。 通过对消息M进行盲化，将盲化后的消息传给签名者进行签名，实现了消息的隐私保护。 该方案存在的问题：签名时使用杂凑函数对盲化后的消息M′进行单向压缩运算，因此实际得到的是盲化消息M′的签名而非待签消息M的签名。 文献 [ 16 ]提出一种基于SM9数字签名 … http://netinfo-security.org/CN/10.3969/j.issn.1671-1122.2024.04.001 smart camera technology
