数字签名Digital Signature Hash函数 本篇内容主要来源于在校学习的Network Security课程,只为有兴趣的初学者打造一个密码学的简单框架,所以尽量隐去严格的概念定义,只在提到时做简要说明。系统性的学习还请参考Jonathan Katz and Yehuda Lindell,Introduction to Modern Cryptography一书。 根据不同的分类方法,密码学的一...
In this blog, we’ll discuss what is Digital Signature in Cryptography, how it is created, the digital signature algorithms, and the various types of digital signature.
Here’s an easy to understand analogy to help your non-technical friends and customers understand public keys and private keys, and how they relate to cryptography and digital signatures.

When the message is received, the digital signature can be retrieved and the sender's public key applied in a decryption operation, which yields the original hash value of the message. A comparison of this hash value with the hash value of the received message can then be performed. Because...
Examples of public-key cryptography or asymmetric-key cryptography include Diffie-Hellman key exchange, RSA (Rivest–Shamir–Adleman), DSA (Digital Signature Algorithm), ECC (elliptic curve cryptography), and post-quantum cryptography. 3. Hash Functions Hash functions use a one-way encryption algorithm...
数字签名(Digital Signature) 非对称加密系统的应用之一 Alice利用她的私钥(kRAkRA)加密签名,Bob用Alice的公钥(kUAkUA)进行解密,证实该消息确实是由Alice本人发送的。 EkUA(DkRA(m))=mEkUA(DkRA(m))=m RSA加密系统 陷门函数("Trap door" one-way function) 在理论计算机科学和密码学中,陷门函数是一种在一个...
Digital signatures and hash functions are used for authentication and ensuring data integrity. A digital signature created with cryptography provides a means of non-repudiation, ensuring that a message's sender cannot deny the authenticity of their signature on a document. ...
可证明安全签名算法(Digital Signature),当前热点是Signatures based on preimage sampleable trapdoor functions。 其他一些有价值的论文,可以在这个链接中找到:Lattice Cryptography & Reduction。 然而,由于此篇综述是2008年完成的,LBC中最热门的方向:Fully Homomorphic Encryption(FHE,全同态加密),Multilinear Groups(多线...
数字签名(Digital Signature): 签名:使用私钥对数据进行签名,生成数字签名。私钥必须保密,由消息的发送者持有。 验证:任何人可以使用公钥验证数字签名的真实性,确保消息没有被篡改,并且确实是由私钥持有者签署的。 示例:Alice 用她的私钥对文档进行签名,Bob 使用 Alice 的公钥验证签名,确认文档的真实性。 共享秘密(Co...
