Public key cryptography can introduce significant processing delays in vehicular communication platforms. This can lead to serious performance issues, especially in the case of multi-hop Inter-Vehicle Communication. In this paper we propose Adaptive Messag ...
New trends in consumer electronics have created a strong demand for fast, reliable and user-friendly key agreement protocols. However, many key agreement protocols are secure only against passive attacks. Therefore, message authentication is often unavoida ...
The author focuses on the cryptographic protection of e-passports, working from the assumption that even if people can peacefully live with their e- passports, what sort of cryptography technology is involved here? Can e- passport holders protect their pri ...
Since the late 70’s, several public key cryptographic algorithms have been proposed. Diffie and Hellman first came with this concept in 1976. Since that time, several other public key cryptosystems were invented, such as the well known RSA, ElGamal or Rabin c ...
Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bit “1”, but not the contrary), we propose integrity codes (I-codes) for a radio co ...
Since the development of cryptology in the industrial and academic worlds in the seventies, public knowledge and expertise have grown in a tremendous way, notably because of the increasing, nowadays almost ubiquitous, presence of electronic communication m ...
Despite many good (secure) key agreement protocols based on public-key cryptography exist, secure associations between two wireless devices are often established using symmetric-key cryptography for cost reasons. The consequence is that common daily used s ...
A secure communication over an insecure channel without any prior exchanged key can be established with the help of an authentication step to exchange a public key and then using public-key cryptography such as RSA. In this work, we concentrate on message ...
At Crypto 2004, van Dijk and Woodruff introduced a new way of using the algebraic tori Tn in cryptography, and obtained an asymptotically optimal n/ϕ(n) savings in bandwidth and storage for a number of cryptographic applications. However, the compu ...
It is sometimes argued that finding meaningful hash collisions might prove difficult. We show that for several common public key systems it is easy to construct pairs of meaningful and secure public key data that either collide or share other characteristi ...
