Efficient Threshold Signature Scheme [PDF]
International Journal of Advanced Computer Science and Applications, 2012 In this paper, we introduce a new threshold signature RSA-typed scheme. The proposed scheme has the characteristics of un-forgeable and robustness in random oracle model. Also, signature generation and verification is entirely non-interactive. In addition, the length of the entity signature participate is restricted by a steady times of the length of ...

The Non--Ergodicity Threshold: Time Scale for Magnetic Reversal [PDF]
, 2005 We prove the existence of a non-ergodicity threshold for an anisotropic classical Heisenberg model with all-to-all couplings. Below the threshold, the energy surface is disconnected in two components with positive and negative magnetizations respectively.

Signcryption schemes with threshold unsigncryption, and applications [PDF]
, 2014 The final publication is available at link.springer.comThe goal of a signcryption scheme is to achieve the same functionalities as encryption and signature together, but in a more efficient way than encrypting and signing separately. To increase security

Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]
, 2000 Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).

Threshold Lattice-Based Signature Scheme for Authentication by Wearable Devices
Cryptography, 2023 This paper presents a new threshold signature scheme based on Damgaard’s work. The proposed scheme allows for changing the message signature threshold, thereby improving the flexibility of the original Damgaard scheme.

Non-Markovian Decay and Lasing Condition in an Optical Microcavity Coupled to a Structured Reservoir [PDF]
, 2006 The decay dynamics of the classical electromagnetic field in a leaky optical resonator supporting a single mode coupled to a structured continuum of modes (reservoir) is theoretically investigated, and the issue of threshold condition for lasing in ...

Research Progress and Prospect of Ring Signatures [PDF]
Jisuanji kexue yu tansuo, 2023 As a special group signature, ring signature has been widely used in anonymous voting, anonymous deposit and anonymous transaction because it can not only complete the signature without the cooperation of ring members, but also ensure the anonymity of ...

Decoding sequential vs non-sequential two-photon double ionization of helium using nuclear recoil [PDF]
, 2008 Above 54.4 eV, two-photon double ionization of helium is dominated by a sequential absorption process, producing characteristic behavior in the single and triple differential cross sections.

Undetachable Threshold Signatures
, 2001 A major problem of mobile agents is their inability to authenticate transactions in a hostile environment. Users will not wish to equip agents with their private signature keys when the agents may execute on untrusted platforms. Undetachable signatures were introduced to solve this problem by allowing users to equip agents with the means to sign ...

Secure obfuscation for encrypted threshold signatures
Tongxin xuebao, 2020 Aiming at the key leakage security problem of the threshold signature,an encrypted threshold signature functionality was firstly proposed and securely obfuscated.The output of obfuscated circuit could be implemented by any third party without revealing ...
