Dual-proxy key-based threshold signature scheme for ship ad-hoc network

Tongxin xuebao, 2018
In order to solve the problem of message authentication under the conditions of the ship ad-hoc network (SANET),a signature scheme that does not depend on trusted certificate authorities and tamper-proof devices (TPD) was proposed by using the threshold ...

Positron line radiation from halo WIMP annihilations as a dark matter signature [PDF]

We suggest a new signature for dark matter annihilation in the halo: high energy positron line radiation. Because the cosmic ray positron spectrum falls rapidly with energy, e+'s from halo WIMP annihilations can be a significant, clean signal for very ...

Deletable blockchain based on threshold ring signature

Tongxin xuebao, 2019
With the development of blockchain,huge storage space is needed to store all of blockchain data.In addition,data can’t be changed once it is packaged into the chain,and it may be possible for overdue data to take up large storage space.Firstly,a ...

Turning Hash-Based Signatures into Distributed Signatures and Threshold Signatures

IACR Communications in Cryptology
We introduce techniques to transform existing stateful hash based signature (HBS) schemes, such as LMS or XMSS, into efficient threshold and distributed signature schemes. Our approach requires a trusted dealer for setup, and uses a large (up to a few GiB, typically) common reference value for each new public key. The dealer generates the keypair and
