The key method is to reduce the degree of the central HFEv-polynomial while, at the same time, increasing the number of Vinegar variables and Minus equations. The new design speeds up the signature generation process by two orders of magnitude (hundreds of times) compared to QUARTZ. We present also new methods to use multivariate signature schemes to build a white box encryption scheme. This technique is applicable to all existing multivariate signature designs including the HFEV-design and the improvements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multivariate digital signature schemes based on HFEv- and new applications of multivariate digital signature schemes for white-box encryption","description":"We present new designs to choose the parameter sets for more efficient HFEv-based signature schemes.
