Side Channel Cryptanalysis of Product Ciphers

Overview Building on the work of Kocher, we introduce the notion of side-channel cryptanalysis: cryptanalysis using implementation data. We discuss the notion of side-channel attacks and the vulnerabilities they introduce, demonstrate side-channel attacks against three product ciphers---timing attack against IDEA, processor-flag attack against RC5, and Hamming weight attack against DES---and then generalize our research to other cryptosystems.

Any cryptographic primitive, such as a block cipher or a digital signature algorithm, can be thought of in two very different ways.

VoIP threats to watch out for

SIP vulnerabilities The scam was a true multi-channel attack. The bulk of VoIP calls currently being made are still not properly secured and this is leaving businesses open to attack. For instance, security company Core Security Technologies...

The biggest VoIP security threats - and how to stop them

While the above network vulnerabilities present a very real and present danger to businesses deploying VoIP, media attention has lingered on the potential danger of spam over internet telephony, or spit.

Junked: Is this the end of spam and spoof email?

Also, it does not do anything to flag junk email sent by a legitimate company, or identify spam sent from a domain name with a true DomainKeys record. If the signature doesn't check out, the message is probably spam - or a phishing attack designed...

Virtualisation: IT managers warned of security challenges

The notion that the surface area of attack increases - well, there's an opportunity to have less layers running in the machine if it doesn't have a plethora of drivers plugging in and out," Herrod said.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
