On Security of XTR Public Key Cryptosystems Against Side Channel Attacks
The XTR public key system was introduced at Crypto 2000. Application of XTR in cryptographic protocols leads to substantial savings both in communication and computational overhead...

A Practical Public Key Cryptosystem Provably Secure Against Adaptive Chosen Ciphertext Attack
A new public key cryptosystem is proposed and analyzed. The scheme is quite practical, and is provably secure against adaptive chosen ciphertext attack under standard intractabili...

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...

Public-Key Steganography with Active Attacks
A complexity-theoretic model for public-key steganography with active attacks is introduced. The notion of steganographic security against adaptive chosen-covertext attacks (SS-CC...
