Certificateless Public Key Signature Schemes from Standard Algorithms
Certificateless PKC Implicit certificate Signature
2018/5/2
Certificateless public key cryptography (CL-PKC) is designed to have succinct public key management without using certificates at the same time avoid the key-escrow attribute in the identity-based cry...

attack trapdoor subgroup congruential equations
2016/5/30
In this short report we analyse the security of three schemes proposed by J. H. Park et al. in "Efficient Identity-Based Encryption and Public-Key Signature from Trapdoor Subgroups". The schemes make ...
Efficient Identity-Based Encryption and Public-Key Signature from Trapdoor Subgroups
identity-based encryption trapdoor subgroup RSA modulus
2016/5/24
We present a new Identity-Based Encryption (IBE) scheme from a trapdoor subgroup of Z∗n for an RSA modulus n. In a trapdoor subgroup of Z∗n, a subgroup order is hidden and can be used as a...
