Distributing Security-Mediated PKI
White Paper Threshold cryptography is used to build a back-up and migration technique which allows recovery from a mediator crashing while also avoiding having all mediators share all secrets. The security-mediated approach to PKI offers several advantages... [16 Apr 2008]
Quantum Cryptology
White Paper On the one hand, it is generally accepted that quantum cryptography can provide absolute security for communications between two users. On the other hand, code-breakers in possession of a quantum computer can easily break popular encryption schemes... [10 Apr 2008]
Network Security With OpenSSL: Introduction
White Paper In today's networked world, many applications need security, and cryptography is one of the primary tools for providing that security. The primary goals of cryptography, data confidentiality, data integrity, authentication, and non-repudiation... [25 Oct 2007]
Sun tightens the security screw
News As part of its initiatives, Sun plans to introduce Sun Java System Web Server 7.0 with support for Elliptic Curve Cryptography (ECC). This is not meant to replace current RSA encryption technology with ECC but rather allows the processing of both. [13 Feb 2006]
Comparing Elliptic Curve Cryptography and RSA on 8-Bit CPUs
White Paper Strong public-key cryptography is often considered to be too computationally expensive for small devices if not accelerated by cryptographic hardware. The authors revisited this statement and implemented elliptic curve point multiplication for 160... [27 Sep 2005]
The Risks of Short RSA Keys for Secure Communications Using SSL
White Paper It describes the nature of the security provided by the cryptography which underlies SSL. This paper considers the risks of using "short", 512 bit keys for the RSA encryption phase used to exchange the keys used in each SSL session. [22 Aug 2005]
Architectural Extensions for Elliptic Curve Cryptography Over GF(2m)
White Paper This paper describes data path extensions for general-purpose microprocessors to accelerate the emerging public-key cryptosystem Elliptic Curve Cryptography (ECC). ECC is computationally more efficient than the popular RSA cryptosystem and, thus... [02 Aug 2005]
A Public-Key Cryptographic Processor for RSA and ECC
White Paper Supported are the legacy cryptosystems RSA and DH as well as the newly emerging Elliptic Curve Cryptography (ECC) system. Due to its computational efficiency, ECC is emerging as an attractive alternative to traditional public-key cryptosystems such... [02 Aug 2005]
Energy Analysis of Public-Key Cryptography for Wireless Sensor Networks
White Paper 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 two nodes in a wireless sensor network. [02 Aug 2005]
A Cryptographic Processor for Arbitrary Elliptic Curves Over GF(2m)
White Paper This paper describes a cryptographic processor for Elliptic Curve Cryptography (ECC). ECC is evolving as an attractive alternative to other public-key cryptosystems such as the Rivest-Shamir-Adleman algorithm (RSA) by offering the smallest key size... [28 Aug 2004]
Minimalist Cryptography for Low-Cost RFID Tags
White Paper This paper explores a notion of minimalist cryptography suitable for RFID tags. A radio-frequency identification (RFID) tag is a small, inexpensive microchip that emits an identifier in response to a query from a nearby reader. [17 Jun 2004]
Securing RFID Tags From Eavesdropping
White Paper While more expensive RFID tags for special environments can do cryptography, ? This paper briefly describes how to protect RFID Tags from Eavesdropping in enterprises. To serve as a successful alternative to barcodes, RFID tags must be very... [17 Jun 2004]
Elliptic Curve Cryptography
White Paper This paper describes an alternative technology, based on mathematical objects known as elliptic curves, which can in some circumstances provide significant benefits over the use of RSA. [20 Apr 2004]
People 'too thick' to cope with viruses
News Even technically sophisticated users will make mistakes, according to Paul Kocher, president of Cryptography Research. Rivest, who has spoken out in the past against cryptography export restrictions, said he favors trying out a system in which the... [25 Feb 2004]
Alternatives to RSA: Using Diffie-Hellman with DSS
White Paper In this note, we describe the important applications of public-key cryptography and show how these Diffie-Hellman (DH) based techniques perform the same functions as RSA. Many vendors who need security for their networking applications often assume... [24 Feb 2004]
