A New Attack with Side Channel Leakage During Exponent Recoding Computations
In this paper we propose a new side channel attack, where exponent recodings for public key cryptosystems such as RSA and ECDSA are considered. The known side channel attacks and c...

Switching Blindings with a View Towards IDEA
Cryptographic algorithms implemented on smart-cards must be protected against side-channel attacks. Some encryption schemes and hash functions like IDEA, RC6, MD5, SHA-1 alternate ...

Pipelined Computation of Scalar Multiplication in Elliptic Curve Cryptosystems
In the current work we propose a pipelining scheme for implementing Elliptic Curve Cryptosystems (ECC). The scalar multiplication is the dominant operation in ECC. It is computed b...

Attacking DSA Under a Repeated Bits Assumption
We discuss how to recover the private key for DSA style signature schemes if partial information about the ephemeral keys is revealed. The partial information we examine is of a se...

Defeating Countermeasures Based on Randomized BSD Representations
Abstract. The recent development of side channel attacks has lead implementers to use increasingly sophisticated countermeasures in critical operations such as modular exponentiati...

Concurrent Error Detection Schemes for Involution Ciphers
Because of the rapidly shrinking dimensions in VLSI, transient and permanent faults arise and will continue to occur in the near future in increasing numbers. Since cryptographic c...
