Public-Key Encryption Resistant to Parameter Subversion and its Realization from Efficiently-Embeddable Groups
Public-key encryption subversion mass surveillance
2018/1/11
We initiate the study of public-key encryption (PKE) schemes and key-encapsulation mechanisms (KEMs) that retain security even when public parameters (primes, curves) they use may be untrusted and sub...
Comment on “Realization of a scalable Shor algorithm”
quantum computer Shor algorithm quantum Fourier transformation
2015/12/21
Recently, Monz, et al. [arXiv:1507.08852] have reported the demonstration
of factoring 15 using a scalable Shor algorithm with an ion-trap quantum
computer. We remark that the report is flawed becau...
Ciphertext-Policy Attribute-Based Encryption:An Expressive, Efficient, and Provably Secure Realization
Ciphertext-Policy Attribute-Based Encryption Bilinear Diffie-Hellman ssumptions generic group model

We present a new methodology for realizing Ciphertext-Policy Attribute Encryption (CP-
ABE) under concrete and noninteractive cryptographic assumptions in the standard model. Our
solutions allow any...
