WebSM9 is a Chinese national cryptography standard for Identity Based Cryptography issued by the Chinese State Cryptographic Authority in ... Algorithm in SM9 traces its origins to a 2003 paper by Sakai and Kasahara titled "ID Based Cryptosystems with Pairing on Elliptic Curve." It was standardized in IEEE 1363.3, in ISO/IEC 18033-5:2015 and ... WebA cryptographic pairing is a bilinear, non-degenerate map that can be computed efficiently. It maps a pair of points in the Jacobian variety into the multiplicative group of a finite field. Pairings were first used in cryptography to attack the DLP on a supersingular elliptic curve by reducing it to the DLP in a finite field that is easier to ...

WebAbstract—Cryptographic pairings are important primitives for many advanced cryptosystems. Efficient computation of pairings requires the use of several layers of algorithms as well as optimizations in different algorithm and implementation levels. This makes implementing cryptographic pairings a difficult task particularly in hardware. WebJun 7, 2024 · The magnitude of the information content associated with a particular implementation of a Physical Unclonable Function (PUF) is critically important for security and trust in emerging Internet of Things (IoT) applications. Authentication, in particular, requires the PUF to produce a very large number of challenge-response-pairs (CRPs) and, … WebImplementing Cryptographic Pairings 179 indeed mr if that has a lower hamming weight for small m). This will clearly result in a faster algorithm. In some cases (e.g. for the MNT curves [34]) the choice of a low Hamming weight order may not be practical, in which case the optimal strategy might be to represent r in a NAF format, and use a standard chromophormodell
