SUMMARY:CRYPTO - Pierre Varjabédian - Multivariate Encryptions with LL' perturbations
DESCRIPTION:Multivariate Encryptions with LL’ perturbations\n\nRésumé:\n\n\nA new interesting multivariate encryption scheme. Few multivariate encryption schemes currently exist\, while there exist many more multivariate signature schemes. Our algorithms will combine several ideas\, in particular the idea of the LL’ perturbation originally introduced\, but only for signatures\, by Gouget and Patarin in Vietcrypt 2006.\n\nIn this paper\, the LL’ perturbation will be used for encryption and will differ greatly from the paper by Gouget and Patarin. As we will see\, our algorithms resist all known attacks (in particular Gröbner attacks and MinRank attacks) and have reasonable computation times.\n\n\n\nLe séminaire sera aussi retranscrit en visio avec le lien suivant:\n\n\n\n\n\n\n\nSujet: Séminaire Pierre Varjabedian\nHeure: 20 avr. 2026 11:00 AM Paris\nParticiper à la réunion Zoom\nhttps://uvsq-fr.zoom.us/j/93830405053?pwd=oHWRB6doOVaM48F2y6hcbMMyQTs7ib.1\n\nID de réunion: 938 3040 5053\nCode secret: 414582
