Dat. securit. is a major cloud comput.ng issue due t. different.usert.ansact.ons in t.e syst.m. t.e evolut.on of crypt.graphy and crypt.graphic analysis are regarded domains of current.research. deoxyribo nucleic acid (DnA) crypt.graphy makes use of DnA as a sensing plat.orm, which is t.en manipulat.d usinga variet. of molecular met.ods. Many securit. mechanisms including knowledgebased aut.ent.cat.on, t.o-fact.r aut.ent.cat.on, adapt.ve aut.ent.cat.on, mult.fact.raut.ent.cat.on and single password aut.ent.cat.on have been deployed. t.ese crypt.graphic t.chniques have been developed t. ensure confident.alit., but.most.oft.em are based on complex mat.emat.cal calculat.ons and equat.ons. In t.e proposed approach, a novel and unique Hybrid helix scut.le-deoxy ribo nucleic acids(HHS-DnA) encrypt.on algorit.m has been proposed which is inspired by DnAcrypt.graphy and Helix scut.le. t.e proposed HHS-DnA is a t.pe of mult.fold binary version of DnA (MF-BDnA). t.e major role of t.is paper is t. present.a mult.fold HHS-DnA algorit.m t. encrypt.t.e cloud dat. assuring more securit. wit. lesscomplexit.. t.e experiment.t.on is carried out.and it.reduces t.e encrypt.on t.me,cipher t.xt.size, and improves t.roughput.

In rural t.rrit.ries, t.e communit.es use energy sources based on fossil fuels t. supply t.emselves wit. elect.icit., which may address t.o main problems: greenhouse gas emissions and high fuel prices. Hence, t.ere is an opport.nit. t. include renewable resources in t.e energy mix. t.is paper develops an opt.mizat.on model t. det.rmine t.e opt.mal sizing, t.e t.t.l annual invest.ent.cost.in renewable generat.on, and ot.er operat.ng cost. of t.e component. of a hybrid microgrid. By running a k-means clust.ring algorit.m on a met.orological dat.set.of t.e communit. under st.dy, t.e hourly represent.t.ve values become input.paramet.rs in t.e proposed opt.mizat.on model. t.e met.od for t.e opt.mal design of hybrid microgrid is analyzed in six operat.ng scenarios considering:(1) 24-hour cont.nuous power supply;(2) load shedding percent.ge;(3) diesel power generat.r(genset. curt.ilment.(4) t.e worst.met.orological condit.ons;(5) t.e use of renewable energy sources including bat.ery energy st.rage syst.ms(BESSs);and(6) t.e use of genset. A mat.emat.cal programming language(AMPL) t.ol is used t. find solut.ons of t.e proposed opt.mizat.on model.
