In this paper, we propose an efficient and secure two-party distributed signing protocol for the SM2 signature algorithm. The latter has been mandated by the Chinese government for all electronic commerce appli
Two oracles accept the same key when the protocol is run in the absence of a malicious adversary. (2) For all probabilistic, polynomial-time (PPT) adversaries, is negligible.3. A Provably-Secure SM2 Key Exchange Protocol 3.1. SM2 Key Exchange Protocol The notations used in SM2 protocol ...
There has been renewed attention to threshold signature in recent years as the threshold version of the ECDSA and SM2 Elliptic Curve Cryptographic Algorithm (SM2) could be used in Bitcoin as an underlying digital signature scheme to protect users’ priva
3.1. SM2 Digital Signature Algorithm The key generation is as follows: (1) The signer randomly selects d as the private key, d∈ [1, q − l]. After that, the public key is calculated (1) The public key P is made public and the private key D is kept secretly. (2) The ...
algorithm of heterogeneous models. This algorithm can aggregate heterogeneous models of various structures into a global large model. In this process, the models of varying scales can all contribute to a unified global large model. We also designed an SM9 threshold signature algorithm-based identity...

The measurement process refers to calculating the hash value of the object through the measurement algorithm and then comparing it with the expected hash value in the TF card. If the two values are the same, we can say that the measured object is trusted. The measurement result will be ...
Signature: To ensure the integrity of 𝑚𝑠ms and realize the identity authentication of the sender, 𝑚𝑠ms needs to be signed by the sender. The detailed processing flow is shown in Algorithm 3, where 𝑋𝑠𝑥Xsx is the x-coordinate of point 𝑋𝑠Xs on the E. After the sig...
