CIPF - dab tsi yog qhov no? cryptographic txhais tau tias ntawm cov ntaub ntawv tiv thaiv

Lub sij hawm "cryptography" derives los ntawm Greek lo lus "thaum" thiab "sau ntawv." Cov kab lus no qhia seb lub hom phiaj tseem ceeb ntawm cryptography - yog kev tiv thaiv thiab tsis pub kis tau cov ntaub ntawv. Kev pab tiv thaiv ntawm cov ntaub ntawv yuav muab qhov chaw nyob rau hauv ntau txoj kev. Piv txwv li, los ntawm limiting lub cev nkag tau mus rau cov ntaub ntawv nkaum kis tau tus mob channel, tsim lub cev muaj teeb meem kev cob cog rua rau kev sib txuas lus kab thiab thiaj li nyob. D.

Lub hom phiaj ntawm cryptography

Tsis zoo li kev cai ntawm cryptography, cryptography yuav tag nrho nyob rau ntawm cov kis channel rau hackers thiab kom tus kheej thiab authenticity ntawm cov ntaub ntawv los ntawm kev siv encryption algorithms uas ua cov ntaub ntawv muab tsis cuag rau tsis tau tso cai nyeem ntawv. Niaj hnub nimno cryptographic tiv thaiv system (CPS) - ib tug software-kho vajtse computer system uas muab kev tiv thaiv ntawm cov nram qab no tsis ntxiv.

• Pub leej twg paub - lub cev tsis mus nyeem cov ntaub ntawv los ntawm cov neeg uas tsis muaj kev tsim nyog saib txoj cai. Lub ntsiab tivthaiv muab pub leej twg paub yog CIPF tseem ceeb (tseem ceeb), uas yog ib tug tshwj xeeb alpha-numeric ib theem zuj zus rau cov neeg siv mus saib tau ib tug tej yam block CIPF.
• Ntseeg - cov impossibility ntawm tsis tau tso cai kev hloov, xws li editing thiab Hmong ntaub ntawv. Yuav kom qhov no yog ntxiv rau daim tseem cia nrog cov lus qhia redundancy nyob rau hauv daim ntawv ntawm ib txoj kev kuaj txawv, xoo los ntawm ib tug cryptographic algorithm thiab nyob ntawm seb tus yuam sij. Yog li, tsis muaj kev txawj ntse ntawm tus yuam sij ntxiv los yog hloov ntaub ntawv yuav tsis yooj yim sua.
• Authentication - authentication ntaub ntawv, thiab ob tog ntawm nws xa thiab tau txais. Kis ntaub ntawv los ntawm kev sib txuas lus raws yuav tsum tau uniquely authenticated cov ntsiab lus, lub sij hawm ntawm kev tsim thiab kis tau tus mob qhov twg los thiab tus neeg. Nws yuav tsum tau nco ntsoov tias qhov uas qhov ntshai heev txawm yuav tsis tau tsuas yog ua tau ib tug attacker, tab sis ob tog koom tes nyob rau hauv cov kev pauv ntawm cov ntaub ntawv nrog me ntsis kev sib nrig sib ntseeg siab. Yuav kom tiv thaiv xws li ib tug teeb meem no siv lub CPS system timestamps rau lub cev tsis rov-reference los yog tawm tswv yim ntxiv, thiab hloov qhov kev txiav txim ntawm nws ib theem zuj zus.

• Authorship - pov thawj thiab uas tsis yog-repudiation ntawm cov kev ua tau los ntawm tus neeg siv cov lus qhia. Feem ntau txoj kev mus kuaj xyuas yog lub tshuab hluav taws xob cov kos npe (Eds). Eds system muaj ob algorithms: ib tug kos npe rau creation thiab pov thawj. Nrog hnyav siv cov Ecc pom zoo siv ntawm software ntawv pov thawj zov me nyuam rau lub creation thiab cov kev tswj ntawm kos npe. Cov chaw zov me nyuam tej zaum yuav muab los siv raws li ib tug tag nrho ywj siab los ntawm cov internal qauv CIPF txhais tau tias. Qhov no txhais li cas rau hauv lub koom haum? Qhov no txhais tau tias tag nrho cov muas yog ua nrog rau hauv kos npe pov thawj los ntawm ywj siab koom haum thiab counterfeiting ntawm authorship yog zoo tsis yooj yim sua.
