A tutorial on public key cryptography

Computers and Security, 1982
Abstract Public key cryptography provides the means for establishing instantaneous, secure communication between any two persons or any two computers. The prior exchange of a secret quantity, called the cryptographic key, is not necessary. In this paper, the underlying mathematical principles of public key (PK) cryptography are informally introduced ...

Public-key cryptography and password protocols

Proceedings of the 5th ACM conference on Computer and communications security, 1998
We study protocols for strong authentication and key exchange in asymmetric scenarios where the authentication server possesses ~a pair of private and public keys while the client has only a weak human-memorizable password as its authentication key. We present and analyze several simple password authentication protocols in this scenario, and show that ...

Public-Key Cryptography and Availability

2005
When the safety community designs their systems to also maintain security properties, it is likely that public-key encryption will be among the tools that are applied. The security guarantees of this technology are based on a particular model of computation.

Introduction to Public-Key Cryptography

2005
In this chapter we introduce the basic building blocks for cryptography based on the discrete logarithm problem that will constitute the main motivation for considering the groups studied in this book. We also briefly introduce the RSA cryptosystem as for use in practice it is still an important public-key cryptosystem.

Public-Randomness in Public-Key Cryptography

1991
In this work we investigate the power of Public Randomness in the context of Public-key cryptosystems. We consider the Diffie-Hellman Public-key model in which an additional short random string is shared by all users. This, which we call Public-Key Public-Randomness (PKPR) model, is very powerful as we show that it supports simple non-interactive ...
