Plaintext-Checkable Encryption
We study the problem of searching on encrypted data, where the search is performed using a plaintext message or a keyword, rather than a message-specific trapdoor as done by state...

Ergodic HMM-UBM System for On-Line Signature Verification
Abstract. We propose a novel approach for on-line signature verification based on building HMM user models by adapting an ergodic Universal Background Model (UBM). State initializa...

Security Flaws in Several Group Signatures Proposed by Popescu
In resent years, Popescu proposed several group signature schemes based on the Okamoto-Shiraishi assumption in [8–11], and claimed his schemes are secure. However, this paper dem...

Universal Algebra in Type Theory
We present a development of Universal Algebra inside Type Theory, formalized using the proof assistant Coq. We define the notion of a signature and of an algebra over a signature. ...

On the Security of Digital Signature Schemes Based on Error-Correcting Codes
In this paper we discuss the security of digital signature schemes based on error? correcting codes. Several attacks to the Xinmei scheme are surveyed, and some reasons given to e...
