Fault Attacks Against RSA-CRT Implementation
RSA-CRT uses the Chinese Remainder Theorem to speed up the computation of an RSA decryption or a signature and reduces the size of the data stored in memory. This implementation is four times faster than the R...

A Probing Attack on AES
The Advanced Encryption Standard (AES) defines the most popular block cipher. It is commonly used and often implemented on smart cards. In this paper, we show how a 128-bit AES key can be retrieved by micropro...

RFID Distance Bounding Protocol with Mixed Challenges to Prevent Relay Attacks
RFID systems suffer from different location-based attacks such as distance fraud, mafia fraud and terrorist fraud attacks. Among them mafia fraud attack is the most serious since this attack can be mounted wit...

The Swiss-Knife RFID Distance Bounding Protocol
Relay attacks are one of the most challenging threats RFID will have to face in the close future. They consist in making the verifier believe that the prover is in its close vicinity by surreptitiously forward...

Method for Detecting Vulnerability to Doubling Attacks
The doubling attack by Fouque and Valette and its analogue, the relative doubling attack, by Yen et al. are a new kind of simple power analysis that can be applied to a binary double-and-add algorithm in a sca...

New Differential Fault Analysis on AES Key Schedule: Two Faults Are Enough
In this paper we show a new differential fault analysis (DFA) on the AES-128 key scheduling process. We can obtain 96 bits of the key with 2 pairs of correct and faulty ciphertexts enabling an easy exhaustive ...

Fault Attacks for CRT Based RSA: New Attacks, New Results, and New Countermeasures
Nowadays RSA using Chinese Remainder Theorem (CRT) is widely used in practical applications. However there is a very powerful attack against it with a fault injection during one of its exponentiations. Many count...

Safe-Error Attack on SPA-FA Resistant Exponentiations Using a HW Modular Multiplier
The RSA is one of the most widely used algorithms nowadays in smart cards. The main part of RSA is the modular exponentiation composed of modular multiplications. Therefore most smart cards have a hardware mod...

Practical Pay-TV Scheme Using Traitor Tracing Scheme for Multiple Channels
A Pay-TV scheme broadcasts a set of services or streams instead of one. That is, a pay-TV scheme is a specific application of a broadcast encryption scheme in which the secret to be broadcast is associated wit...

An Efficient Revocation Scheme for Stateless Receivers
A revocation scheme for stateless receivers enables the center to deliver information securely to the legitimate users over a public channel, where the receivers do not update their state from session to sessi...

TTS without Revocation Capability Secure Against CCA2
A traitor tracing scheme (TTS) deters traitors from giving away their secret keys to decrypt the transmitted data by enabling the system manager to trace at least one of the traitors who participated in the co...

An Efficient Revocation Scheme with Minimal Message Length for Stateless Receivers
We deal with the revocation scheme such that the revoked receivers should not be able to obtain available information when a center broadcasts data to all receivers. We propose a new revocation scheme with min...

An Efficient Public Key Trace and Revoke Scheme Secure against Adaptive Chosen Ciphertext Attack
We propose a new public key trace and revoke scheme secure against adaptive chosen ciphertext attack. Our scheme is more efficient than the DF scheme suggested by Y. Dodis and N. Fazio[9]. Our scheme reduces t...
