Public key encryption

ACM SIGSAM Bulletin, 1987
The RSA method is used for the interchange of secret messages via insecure channels. It is elegant in theory and fast and reliable in practice. Applications are in the field of communication networks.The method is initialized by choosing some suitable large prime numbers. Encrypting and decrypting of a message are done by modular arithmetic.

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 ...

Public-Key Encryption

1999
Public-key algorithms use a secret element and a public element to their code. One of the main algorithms is RSA. Compared with DES it is relatively slow but it has the advantage that users can choose their own key whenever they need one. The most commonly used public-key cryptosystems are covered in the next sections.

Key Privacy in McEliece Public Key Cryptosystem

2011IEEE 10th International Conference on Trust, Security and Privacy in Computing and Communications, 2011
the research on the anonymity of original McEliece PKC points out that the original McEliece PKC fails to hold the property of key privacy. A novel semantically secure variant of McEliece PKC is proposed, and proved its anonymity formally in standard model.

Public key vs. conventional key encryption

1979 International Workshop on Managing Requirements Knowledge (MARK), 1979
As distributed computer systems grow and their convenience attracts uses for which maintenance of privacy and security is important, the means by which encryption is integrated into these systems also becomes important. Encryption is the only practical way by which secure, private communication can be conducted while employing untrusted media to carry ...

Reasoning about public-key certification: on bindings between entities and public keys

IEEE Journal on Selected Areas in Communications, 1999
Public-key certification is of crucial importance for advancing the global information infrastructure, yet it suffers from certain ambiguities and lack of understanding and precision. This paper suggests a few steps towards basing public-key certification and public-key infrastructures on firmer theoretical grounds.

THE PUBLIC KEY COVERT CHANNEL

Cryptologia, 2005
One aspect of Public Key Cryptography often overlooked is that it contains a channel that can be exploited covertly. In this paper we will explore this channel as it relates to the RSA cryptosystem.

A public-key-based key escrow system

Journal of Systems and Software, 1996
A key escrow system allows devices such as telephones or computers to communicate securely, while permitting a monitor such as a law enforcement agency to access encrypted communications under prescribed conditions. The U.S. government has created an escrow system using secret-key cryptography and classified algorithms, implementable in hardware only ...
