In the development of TLS 1.3, the IETF TLS Working Group has adopted an “analysis-prior-to-deployment” design philosophy. This is in sharp contrast to all previous versions of the protocol. We present an account of the TLS standardisation narrative, examining the differences between the reactive standardisation process for TLS 1.2 and below, and the more proactive standardisation process for T...

Transport Layer Security (TLS) is the fundament of today’s web security, but the majority of deployments are misconfigured and left vulnerable to a phletora of attacks. This negatively affects the overall healthiness of the TLS ecosystem, and as such all the protocols that build on top of it. Scanning a larger number of hosts or protocols such as the numerous IPv4-wide scans published recently ...

Tor constitutes one of the pillars of anonymous online communication. It allows its users to communicate while concealing from observers their location as well as the Internet resources they access. Since its first release in 2002, Tor has enjoyed an increasing level of popularity with now commonly more than 2,000,000 simultaneous active clients on the network. However, even though Tor is widel...

background: tumor lysis syndrome (tls) is a major metabolic complication in patients with malignancy after initiation of chemotherapy or spontaneously without treatment. the role of rasburicase (a recombinant urate-oxidase enzyme) in prevention and treatment of tls has been demonstrated in recent years. we aimed to investigate the efficacy of a single dose of rasburicase in reducing the risk of...

Mobile IPv6 usually use the IPsec/IKEv2 to secure Mobile Node (MN) and Home Agent (HA) communication. The implementation of IPsec/IKEv2 with MIPv6 is complex because it requires a tight coupling between MIPv6 protocol part and the IPsec/IKEv2 part of the IP stack. This paper proposes a security mechanism which uses Transport Layer Security (TLS) for establishing Keying Material and other bootst...

Transport Layer Security (TLS) implementations have a history of security flaws. The immediate causes of these are often programming errors, e.g. in memory management, but the root causes are more fundamental: the challenges of interpreting the ambiguous prose specification, the complexities inherent in large APIs and code bases, inherently unsafe programming choices, and the impossibility of d...

This memo explains how to use the Upgrade mechanism in HTTP/1.1 to initiate Transport Layer Security (TLS) over an existing TCP connection. This allows unsecured and secured HTTP traffic to share the same well known port (in this case, http: at 80 rather than https: at 443). It also enables "virtual hosting", so a single HTTP + TLS server can disambiguate traffic intended for several hostnames ...

An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...
