In order to improve the confidentiality of the private key generator(PKG)in identity-based encryption-signature(IBES)scheme,we improve the Xavier IBES scheme,and use(t,n)secret sharing scheme of threshold cryptography to split the master secret s among n peer to peer third PKGs.We apply the new IBES scheme in wireless sensor network,and discuss its efficiency and security in terms of complexity,storage requirement and security.Analysis shows that our scheme can efficiently improve the confidentiality of the PKG and the security of wireless sensor network.

Quantum attack-resistant signature scheme from lattice cryptography for WFH

Luyao Wang, Chunguang Huang, Hai Ying Cheng

With the emergence of quantum computers, traditional digital signature schemes based on problems such as large integer solutions and discrete logarithms will no longer be secure, and it is urgent to find effective digital signature schemes that can resist quantum attacks. Lattice cryptography has the advantages of computational simplicity and high security. In this paper, we propose an identity-based digital signature scheme based on the rejection sampling algorithm. Unlike most schemes that use a common Gaussian distribution, this paper uses a bimodal Gaussian distribution, which improves efficiency. The identity-based signature scheme is more convenient for practical application than the traditional certificate-based signature scheme.

Identity-based proxy blind signature scheme on lattice in high-speed network environment

Mengjiao Yang, Dongmei Ke, Fengyin Li

The methods of network attacks are becoming more and more diverse In high-speed networks, and protecting private data is a key issue for users’ security. Proxy blind signature technology combines proxy and blind signature technology to achieve signature transitivity and message confidentiality. However, current signature schemes will not be secure in quantum environments. Meanwhile, the certificate storage of the existing scheme is relatively complicated. Therefore, to avoid the need for certificates and resist quantum attacks, this paper proposes an anti-quantum identity-based proxy blind signature (ID-Proxy-BS) scheme on lattice. This ID-Proxy-BS scheme improves the efficiency of signature through Gaussian distribution and sampling techniques. Security analysis shows that the scheme satisfies correctness, efficiency, blindness, and unforgeability.
