Indifferentiability for Public Key Cryptosystems

2020
We initiate the study of indifferentiability for public key encryption and other public key primitives. Our main results are definitions and constructions of public key cryptosystems that are indifferentiable from ideal cryptosystems, in the random oracle model.

Protocols for Public Key Cryptosystems

1980 IEEE Symposium on Security and Privacy, 1980
New Cryptographic protocols which take full advantage of the unique properties of public key cryptosystems are now evolving. Several protocols for public key distribution and for digital signatures are briefly compared with each other and with the conventional alternative.

Multivariate Public Key Cryptosystems

2017
This paper presents a survey on the multivariate public key cryptosystem (MPKC), which is a public key cryptosystem whose public key is a set of multivariate quadratic forms over a finite field.

Searching for Public-Key Cryptosystems

1984 IEEE Symposium on Security and Privacy, 1984
This article suggests the use of undecidable problems in constructing public-key cryptosystems. Any such system must still be in NP, but intuitive arguments suggest that this approach might be a reasonable alternative to the use of NP-complete problems.

Finite Automaton Public Key Cryptosystems

2009
Since the introduction of the concept of public key cryptosystems by Diffie and Hellman[32], many concrete cryptosystems had been proposed and found applications in the area of information security; almost all are block. In this chapter, we present a sequential one, the so-called finite automaton public key cryptosystem; it can be used for encryption ...
