This article presents a family of cryptographic ASICs, called SecMat, designed in CMOS 130 nanometer technology by the authors with the help of STMicroelectronics. The purpose of ...
It is a well known problem that the attack recovery of a self-healing system rolls back not only malicious transactions, but also legitimate transactions that are dependent on the...
A group signature scheme allows a group member to sign messages anonymously on behalf of the group, while in case of a dispute, a designated entity can reveal the identity of a si...
The Elliptic Curve Digital Signature Algorithm admits a natural parallelization wherein the point multiplication step can be split in two parts and executed in parallel. Further pa...
As the core operation of many public key cryptosystems, group exponentiation is central to cryptography. Attacks on its implementation in embedded device setting is hence of great ...
