(pbc)Pairing-Based Cryptography是实现双线性对运算的 函數库,但没有异或XOR函數,我参考编写了一个,希望对大家有 帮助. 编译命令: gcc -o xor xor.c -I /usr/local/include/pbc -L /usr/local/lib -Wl,-rpath /usr/local/lib -lpbc 运行:./xor ...
PBC库的安装测试完成。 在PBC库上,将可以完成诸多的密码学实验,库中也提供了一些密码学实例。

This week we look at what the BLS pairing-based signature scheme is. Seeherefor full details. 本周我们来看看什么是基于BLS配对的签名方案。请参阅此处了解详细信息。 This signature scheme makes use of the Weil pairing on elliptic curves, essentially a bilinear form (with multiplicative notation) on...
Since mobile devices are generally resource-constrained and cloud services are Internet-based and pay-by-use, a key feature in ciphertext-policyAttribute-based encryption (CP-ABE) should be constant sizes for secret keys and ciphertexts.In this paper, we propose a new pairing-based CP-ABE schem...

如果将参与方扩展到3个,很自然的问题是这种3方单次交互的协议是否可以抵抗eve。该问题在2000年是被Joux通过一个相当简单的bilinear pairing的方式解决。 Three-party two-round key agreement protocol 自此,基于pairings的方案变得非常流行。 【1】Alfred Menezes An Introduction to Pairing-Based Cryptography ...
