On Provable Security for Complex Systems
We investigate the contribution of cryptographic proofs of security to a systematic security engineering process. To this end we study how to model and prove security for concrete applications in three practical domains: computer networks, data outsourcing, and electronic voting.

Provably secure secret sharing scheme based on bilinear maps
A method to construct provable secure secret sharing scheme using bilinear pairing was recommended.Firstly,the semantic security definition for secret sharing scheme is given,which is developed from the standard definition of semantic security for the ...

Comprehensive Analysis and Implementation of Isogeny-Based Hash Functions
This paper analyzes the security and performance of the isogeny-based hash functions. The isogeny-based hash function was first proposed by Charles, Goren, and Lauter, and is referred to as the CGL hash function.

Provably secure and efficient escrowable public key encryption schemes
In an escrowable public key encryption (E-PKE) scheme, there are two keys associated with one public key. It can reduce the total number of certificates in the public key infrastructure (PKI) to a large extent, thus degrade the com-plexity of certificate

Analysis and improvement of an ID-based authenticated key agreement protocol
The security of a recently proposed ID-based authenticated key agreement protocol was analyzed. Although it is provably secure in the standard model, a malicious PKG (private key generator) can still obtain all of the agreed ses-sion keys, that is, it ...

Provably secure certificateless aggregate signature scheme in wireless roaming authentication
Certificateless aggregate signature (CLAS) schemes have been widely applied in resource-constrained wireless mobile networks,because they could not only realize batch validation but also solve the certificate management and key escrow problems.It was ...

Correcting the security definition of the Bellare-Rogaway 3PKD model
A flaw lied in the security definition of the Bellare-Rogaway 3PKD model,which was proposed by Bellare and Rogaway for three-party key distribution in 1995,was discovered.To reveal it,a new three-party key distribution proto-col P-Flaw was proposed.The ...
