A first-order chosen-plaintext DPA attack on the third round of DES
side-channel attack DPA countermeasure
2018/1/2
DPA attacks usually exhibit a "divide-and-conquer" property: the adversary needs to enumerate only a small space of the key (a key sub-space) when performing the DPA attack. This is achieved trivially...
New Cube Root Algorithm Based on Third Order Linear Recurrence Relation in Finite Field
applications / cube root algorithm Cipolla-Lehmer algorithm
2013/2/21
In this paper, we present a new cube root algorithm in finite field $\mathbb{F}_{q}$ with $q$ a power of prime, which extends the Cipolla-Lehmer type algorithms \cite{Cip,Leh}. Our cube root method is...
Structure Preserving CCA Secure Encryption and Its Application to Oblivious Third Parties
CCA Secure Encryption Oblivious Third Parties
2011/7/25
In this paper we present the first public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations.
Structure Preserving CCA Secure Encryption and Its Application to Oblivious Third Parties
cryptographic protocols / public-key encryption structure preserving oblivious party
2012/3/27
In this paper we present the first public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations. In particular it does not use hash-functions o...
A Practical-Time Attack on the A5/3 Cryptosystem Used in Third Generation GSM Telephony
Practical-Time Attack A5/3 Cryptosystem Third Generation GSM Telephony
2010/1/18
The privacy of most GSM phone conversations is currently
protected by the 20+ years old A5/1 and A5/2 stream ciphers, which
were repeatedly shown to be cryptographically weak. They will soon be
rep...
Unlinkable Divisible Digital Cash without Trusted Third Party
digital cash divisibility unlinkability
2008/8/25
We present an efficient divisible digital cash scheme which is unlinkable and does not require
Trusted Third Party. The size of the coin is proportional to the size of the primes we use,
i.e., hundr...
