In cryptography, the Unbalanced Oil and Vinegar scheme is a modified version of the Oil and Vinegar scheme designed by J. Patarin. Both are digital signature schemes. They belong to the group of multivariate cryptography. The security of this signature scheme is based on an NP-hard mathematical problem. To create and validate signatures a minimal quadratic equations system has to be solved. Solving m equations with n variables is an NP-hard problem, even when using a real existing quantum computer. Therefore, the signature schemes based on multivariate equations systems are considered to be quantum resistant.

Famous quotes containing the words unbalanced, oil and/or vinegar:
“However, the danger in [socially unbalanced relationships] is that the subjection of the woman temporarily calms the man’s jealousy but also renders it more demanding. He ends up making his mistress live like those prisoners on whom light is shone day and night in order for them to be better watched. And things always end in tragedy.”
—Marcel Proust (1871–1922)
“His education lay like a film of white oil on the black lake of his barbarian consciousness. For this reason, the things he said were hardly interesting at all. Only what he was.”
—D.H. (David Herbert)
“He packs wool sheared in April, honey
in combs, linen, leather
tanned from deerhide,
and vinegar in a barrel
hooped by hand at the forge’s fire.”
—Donald Hall (b. 1928)
