Public Key Cryptography on RFID Tags: "A Survey on the GPS Identification Scheme"

In the last few years, a lot of research effort has been made in the area of Radio Frequency Identification RFID technology. The widespread deployment of RFID tags and their increased usage in open environments brought on surface a need for supporting more advanced security features. Applying public-key cryptography constitutes...

Social networks have taught us cryptography (probably) won't stop spam

On a regular basis I receive blog comments and suggestions on what magical technologies will put spam out of business. There are many valid techniques for stopping spam, but signing e-mails and e-mail senders is not one of them. After my recent post on the impact...

Containing Denial-of-Service Attacks in Broadcast Authentication in Sensor Networks

Broadcast authentication is an important application in sensor networks. Public Key Cryptography PKC is desirable for this application, but due to the resource constraints on sensor nodes, these operations are expensive, which means sensor networks using PKC are susceptible to Denial of Service DoS attacks: attackers keep broadcasting bogus messages,...

Energy Analysis of Public-Key Cryptography for Wireless Sensor Networks

In this paper, the energy cost of authentication and key exchange are quantified based on public-key cryptography on an 8-bit microcontroller platform. The paper presents a comparison of two public-key algorithms, RSA and Elliptic Curve Cryptography ECC, and considers mutual authentication and key exchange between two untrusted parties such as...

Using Public Key Cryptography in Mobile Phones

As mobile networks expand their bandwidth, mobile phones, as with any other Internet device, become substantially exposed to Internet security vulnerabilities. Public key cryptography is a primary concept in implementing wireless device security. Many papers have been written about public key infrastructure, this paper does not...

Introduction to Public Key Cryptography

The solution to problems of identification, authentication, and privacy in computer-based systems lies in the field of cryptography. Because of the non-physical nature of the medium, traditional methods of physically marking the media with a seal or signature for various business and legal purposes are useless.

Legal concerns stop researchers from disrupting the Storm Worm botnet

What if security researchers were able to disrupt the leftovers of the Storm Worm botnet thanks to a flaw in its communication model allowing them to redirect infected hosts and eventually disinfect them, but fearing legal action have their hands tied? At the 25th Chaos Communication Congress,...

Achieve Information Security by Preserving the Secrecy and Integrity of Keys

Cryptography forms the basis of information security infrastructure. Data encryption, network traffic encryption, PKI-based authentication and digital signatures all depend on the underlying confidentiality of secret keys and integrity of public certificate authority keys to function as intended. When keys are compromised, information security systems cannot protect data. First-tier technologies...
