The Datagram Transport Layer Security (DTLS) Protocol Version 1.3
2020Co-Authors: Eric Rescorla, H. (arm Limited) Tschofenig, Nagendra ModaduguAbstract:This document specifies Version 1.3 of the Datagram Transport Layer Security (DTLS) protocol. DTLS 1.3 allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery. The DTLS 1.3 protocol is intentionally based on the Transport Layer Security (TLS) 1.3 protocol and provides equivalent security guarantees with the exception of order protection/non-replayability. Datagram semantics of the underlying Transport are preserved by the DTLS protocol.

the Transport Layer security tls protocol version 1 3
RFC, 2018Co-Authors: Eric RescorlaAbstract:This document specifies version 1.3 of the Transport Layer Security (TLS) protocol. TLS allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery. This document updates RFCs 4492, 5705, and 6066 and it obsoletes RFCs 5077, 5246, and 6961. This document also specifies new requirements for TLS 1.2 implementations.

the datagram Transport Layer security dtls connection identifier
2017Co-Authors: Thomas Fossati, Eric Rescorla, Tobias Gondrom, H. (arm Limited) TschofenigAbstract:This document specifies the "Connection ID" concept for the Datagram Transport Layer Security (DTLS) protocol, version 1.2 and version 1.3. A Connection ID is an identifier carried in the record Layer header that gives the recipient additional information for selecting the appropriate security association. In "classical" DTLS, selecting a security association of an incoming DTLS record is accomplished with the help of the 5-tuple. If the source IP address and/or source port changes during the lifetime of an ongoing DTLS session then the receiver will be unable to locate the correct security context.

unknown key share attacks on uses of Transport Layer security with the session description protocol sdp
2017Co-Authors: Martin Thomson, Eric RescorlaAbstract:Unknown key-share attacks on the use of Datagram Transport Layer Security for the Secure Real-Time Transport Protocol (DTLS-SRTP) and its use with Web Real-Time Communications (WebRTC) identity assertions are described. Simple mitigation techniques are defined.

Datagram Transport Layer Security Version 1.2
rfc 6347, 2012Co-Authors: Eric Rescorla, Nagendra ModaduguAbstract:This document specifies version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. The DTLS protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the Transport Layer Security (TLS) protocol and provides equivalent security guarantees. Datagram semantics of the underlying Transport are preserved by the DTLS protocol. This document updates DTLS 1.0 to work with TLS version 1.2.

efficient planar perovskite solar cells with reduced hysteresis and enhanced open circuit voltage by using pw12 tio2 as electron Transport Layer
ACS Applied Materials & Interfaces, 2016Co-Authors: Chun Huang, Canjun Liu, Fangyang Liu, Liangxing Jiang, Xiaojing Hao, Haitao HuangAbstract:An electron Transport Layer is essential for effective operation of planar perovskite solar cells. In this Article, PW12–TiO2 composite was used as the electron Transport Layer for the planar perovskite solar cell in the device structure of fluorine-doped tin oxide (FTO)-glass/PW12–TiO2/perovskite/spiro-OMeTAD/Au. A proper downward shift of the conduction band minimum (CBM) enhanced electron extraction from the perovskite Layer to the PW12–TiO2 composite Layer. Consequently, the common hysteresis effect in TiO2-based planar perovskite solar cells was significantly reduced and the open circuit voltage was greatly increased to about 1.1 V. Perovskite solar cells using the PW12–TiO2 compact Layer showed an efficiency of 15.45%. This work can contribute to the studies on the electron Transport Layer and interface engineering for the further development of perovskite solar cells.

p i n n i p type planar hybrid structure of highly efficient perovskite solar cells towards improved air stability synthetic strategies and the role of p type hole Transport Layer htl and n type electron Transport Layer etl metal oxides
Nanoscale, 2016Co-Authors: Sawanta S Mali, Chang Kook HongAbstract:There has been fast recent progress in perovskite solar cells (PSCs) towards low cost photovoltaic technology. Organometal mixed halide (MAPbX or FAPbX) perovskites are the most promising light absorbing material sandwiched between the electron Transport Layer (ETL) and hole Transport Layer (HTL). These two Layers play a critical role in boosting the power conversion efficiency (PCE) and maintaining air stability. However, the device stability is a serious issue in regular as well as p-i-n inverted type perovskite solar cells. This mini-review briefly outlines the state-of-art of p-i-n/n-i-p type planar hybrid perovskite solar cells using MAPbX/FAPbX perovskite absorbing Layers. Later, we will focus on recent trends, progress and further opportunities in exploring the air stable hybrid planar structure PSCs.

alternative benzodithiophene bdt based polymeric hole Transport Layer for efficient perovskite solar cells
Solar Energy Materials and Solar Cells, 2017Co-Authors: Eman A Gaml, Ashish Dubey, Khan Mamun Reza, Nazmul Hasan, Nirmal Adhikari, Hytham Elbohy, Behzad Bahrami, H M ZeyadaAbstract:Organic-inorganic perovskite cell has shown a great deal of interest in past few years due to its ability to achieve high power conversion efficiency (PCE). Use of charge Transport Layers such as n-type TiO2 and p-type doped spiroOMeTAD in a n-i-p device architecture has shown enhanced perovskite solar cell device performance. Use of doped spiroOMeTAD as hole Transport Layer in the n-i-p device structure has been effective but possess disadvantages such as complex processing, use of corrosive additives, processing in ambient air for efficient hole doping. Here we report the study of solution processed benzodithiophene based polymer PBDTT-FTTE as an alternative hole Transport Layer to doped small molecule spiroOMeTAD. PBDT-FTTE doped with 3% DIO (diiodooctane) achieved PCE of 11.6% which was comparable to matching PCE of 11.6% obtained from using spiroOMeTAD as hole Transport Layer. We showed that unlike spiroOMeTAD, polymer PBDTT-FTTE is processed inside N2 filled glove box and is easier to process as compared to spiroOMeTAD which requires processing in ambient humid air and is doped with additives mixed in corrosive solvent, causing degradation to perovskite Layer underneath.
