Along with the rapid development and wide application of information technology, human
society has entered the information era. In this era, people live and work in cyberspace …

Biometric Cryptosystem (BCS) combines characteristics of both the fields: biometric and
cryptosystem, where biometric provides authentication and cryptosystem imparts security …

In this paper we propose a new image randomness measure using Shannon entropy over
local image blocks. The proposed local Shannon entropy measure overcomes several …

Implementations of cryptographic algorithms are vulnerable to Side Channel Analysis
(SCA). To counteract it, masking schemes are usually involved which randomize key …

The fair evaluation and comparison of side-channel attacks and countermeasures has been
a long standing open question, limiting further developments in the field. Motivated by this …

This paper considers two questions in cryptography. Cryptography Secure Against Memory
Attacks. A particularly devastating side-channel attack against cryptosystems, termed the …

We construct a stream-cipher S whose implementation is secure even if a bounded amount
of arbitrary (adversarially chosen) information on the internal state ofS is leaked during …

The notion of public key encryption with keyword search (PEKS) was put forth by Boneh et
al. to enable a server to search from a collection of encrypted emails given a “trapdoor”(ie …

Most of the work in the analysis of cryptographic schemes is concentrated in abstract
adversarial models that do not capture side-channel attacks. Such attacks exploit various …

In recent years, there has been a major effort to design cryptographic schemes that remain
secure even when arbitrary information about the secret key is leaked (eg, via side-channel …
