Public Key Cryptography

2006
Non-secret encryption Until relatively recently cryptosystems were always symmetric. They relied on the use of a shared secret key known to both sender and receiver. This all changed in the 1970s. Public key cryptosystems, as they are now called, revolutionised the theory and practice of cryptography by relying for their impenetrability on the ...

A Survey on Post-Quantum Public-Key Signature Schemes for Secure Vehicular Communications

IEEE transactions on intelligent transportation systems (Print), 2022
Basic security requirements such as confidentiality, user authentication and data integrity, are assured by using public-key cryptography (PKC). In particular, public-key signature schemes provide non-repudiation, integrity of transmitted messages and ...

Public-Key Cryptography

2005
Secure transmission of private information is a crucial issue in today’s highly computerized world. Cryptographic algorithms are used to provide privacy of message transmission and to certify authenticity of sender and/or receiver of a message and message integrity as well as undeniability of transmitted messages (Menezes et al., 1996).

Image encryption and decryption in public key cryptography based on MR

International Conference on Computing and Convergence Technology, 2015
In the past decade, image encryption is given much attention in research of information security and a lot of image encryption algorithms have been introduced. Due to some intrinsic features of images like bulk data capacity and high data redundancy, the

Public Key Cryptography

2011
This chapter presents an asymmetric approach to cryptography – it uses different keys for encryption and decryption. The key for encryption is announced publically so that everybody can encode a message. Only the owner of the matching secret key can decode the encrypted message.
