Revisiting the Cubic UOV Signature Scheme

2017
As recently been emphasized by NSA and NIST, there is an increasing need for cryptographic schemes being secure against quantum computer attacks. Especially in the area of digital signature schemes, multivariate cryptography is one of the main candidates for this. At Inscrypt 2015, Nie et al.

On the Security of UOV

IACR Cryptol. ePrint Arch., 2008
In this short note, we investigate the security of the Unbalanced Oil and Vinegar Scheme [16]. To do so, we use a hybrid approach for solving the algebraic systems naturally arising when mounting a signature-forgery attack. The basic idea is to compute Gröbner bases of several modified systems rather than a Gröbner basis of the initial system. It turns

Field Lifting for Smaller UOV Public Keys

2017
Most Multivariate Quadratic (MQ) signature schemes have a very large public key, which makes them unsuitable for many applications, despite attractive features such as speed and small signature sizes. In this paper we introduce a modification of the Unbalanced Oil and Vinegar (UOV) signature scheme that has public keys which are an order of magnitude ...

IBUOV, A Provably Secure Identity-Based UOV Signature Scheme

2013 IEEE 16th International Conference on Computational Science and Engineering, 2013
Multivariate Public Key Cryptosystem (MPKC) is one of post-quantum cryptosystems which can potentially resist quantum computer attacks. It has increasingly been seen by some as a possible alternative to public key cryptosystems RSA, ECC, etc., which are widely in use today.

UOV-Based Verifiable Timed Signature Scheme

Proceedings of the 22nd International Conference on Security and Cryptography
Verifiable Timed Signatures (VTS) are cryptographic primitives that enable the creation of a signature that can only be retrieved after a specific time delay, while also providing verifiable evidence of its existence. This framework is particularly useful in blockchain applications. Current VTS schemes rely on signature algorithms such as BLS, Schnorr,

Online/offline signature based on UOV in wireless sensor networks

Wireless Networks, 2016
Being a member of the post quantum cryptography family, multivariate public key cryptographic (MPKC) system enjoys many useful properties such as fast implementation and moderate resources requirement, which is quite suitable for the wireless sensor network (WSN).

Linear Recurring Sequences for the UOV Key Generation Revisited

2013
Multivariate cryptography is one of the main candidates to guarantee the security of communication in a post quantum era. While multivariate signature schemes are very fast and require only modest computational resources, the key sizes of such schemes are quite large. In [17] Petzoldt et al.

Security Analysis of Improved Cubic UOV Signature Schemes

2018
At ICISC 2016, Duong et al. proposed two signature schemes based on multivariate quadratic equations, CSSv and SVSv by improving the security of the cubic UOV against Hashimoto’s attack. They claimed that the schemes were secure against all known attacks.
