If large-scale quantum computers are ever built, they will be able to break many of the public-key cryptosystems currently in use. This would seriously compromise the confidentiality and integrity of digital communications on the Internet and elsewhere. The goal of post-quantum cryptography (also called quantum-resistant cryptography) is to develop cryptographic systems that are secure against both quantum and classical computers, and can interoperate with existing communications protocols and networks. This Internal Report shares the National Institute of Standards and Technology (NIST) s current understanding about the status of quantum computing and post-quantum cryptography, and outlines NIST s initial plan to move forward in this space. The report also recognizes the challenge of moving to new cryptographic infrastructures and therefore emphasizes the need for agencies to focus on crypto agility. 606 $aPublic key cryptography 606 $aQuantum computing 615 0$aPublic key cryptography. 615 0$aQuantum computing. 700 $aChen$b Lily$01396971 701 $aChen$b Lily$01396971 701 $aJordan$b Stephen$01396972 701 $aLiu$b Yi-Kai$01396973 701 $aMoody$b Dustin$01396974 701 $aPeralta$b Rene?$01396975 701 $aPerlner$b Ray$01396976 701 $aSmith-Tone$b Daniel$01396977 712 02$aInformation Technology Laboratory (National Institute of Standards and Technology) 801 0$bNBS 801 1$bNBS 801 2$bGPO 801 2$bNBS 906 $aBOOK 912 $a9910709596903321 996 $aReport on post-quantum cryptography$93457995 997 $aUNINA LEADER 03932oam 2200481zu 450 001 9910872442503321 005 20241212214836.0 024 7 $a10.1109/ULTSYM.1998 035 $a(CKB)111026746719484 035 $a(SSID)ssj0000455018 035 $a(PQKBManifestationID)12175363 035 $a(PQKBTitleCode)TC0000455018 035 $a(PQKBWorkID)10399412 035 $a(PQKB)10296563 035 $a(NjHacI)99111026746719484 035 $a(EXLCZ)99111026746719484 100 $a20160829d1999 uy 101 0 $aeng 135 $aur||||||||||| 181 $ctxt 182 $cc 183 $acr 200 10$a1998 IEEE Ultrasonics Symposium 210 31$a[Place of publication not identified]$cIEEE$d1999 215 $a1 online resource $cillustrations 300 $aBibliographic Level Mode of Issuance: Monograph 311 08$a9780780340954 311 08$a0780340957 327 $a1998 IEEE Ultrasonics Symposium -- Silicon micromachined ultrasonic transducers -- Effect of wraparound electrodes on ultrasonic array performance -- A 2.5 MHz phased linear array made from stacked piezoelectric composite -- Defect imaging by micromachined ultrasonic air transducers -- A new detection method for capacitive micromachined ultrasonic transducers -- Optimization of a sandwich driver structure using Finite Element Analysis -- Measurement of spectral response of ultrasonic probes.

The aim is to interpret experiments on surface acoustic wave monitoring of the wetting of high-energy solid surfaces (G. McHale et al., Furaday. Discuss., 1997, 107, 27-38). These experiments demonstrated a strong oscillatory behaviour of both transmission and reflection coefficients as the area occupied by the liquid increased with time. The variable thickness of the liquid is taken into account and analmcal results and numerical calculations are presented. 606 $aUltrasonic waves$vCongresses 606 $aUltrasonics$vCongresses 615 0$aUltrasonic waves 615 0$aUltrasonics 676 $a534.55 700 $aSchneider$b S.
