Adaptive Security in the Threshold Setting: From Cryptosystems to Signature Schemes
Threshold cryptosystems and signature schemes give ways to distribute trust throughout a group and increase the availability of cryptographic systems. A standard approach in design...

RSA-OAEP Is Secure under the RSA Assumption
Recently Victor Shoup noted that there is a gap in the widely-believed security result of OAEP against adaptive chosen-ciphertext attacks. Moreover, he showed that, presumably, OA...

Multiparty Computation for Dishonest Majority: From Passive to Active Security at Low Cost
Multiparty computation protocols have been known for more than twenty years now, but due to their lack of efficiency their use is still limited in real-world applications: the goal...

Unlinkable Randomizable Signature and Its Application in Group Signature
We formalize a generic method of constructing efficient group signatures, specifically, we define new notions of unlinkable randomizable signature, indirectly signable signature ...

Selecting Parameters for the Rainbow Signature Scheme
Abstract. Multivariate public key cryptography is one of the main approaches to guarantee the security of communication in a post-quantum world. One of the most promising candidate...
