A workaround for SSL 3.0 and TLS 1.0, roughly equivalent to random IVs from TLS 1.1, was widely adopted by many implementations in late 2011. [30] In 2014, the POODLE vulnerability of SSL 3.0 was discovered, which takes advantage of the known vulnerabilities in CBC, and an insecure fallback negotiation used in browsers.
TLS 1.1 was defined in RFC 4346 in April 2006. [43] It is an update from TLS version 1.0. Significant differences in this version include: Added protection against cipher-block chaining (CBC) attacks. The implicit initialization vector (IV) was replaced with an explicit IV. Change in handling of padding errors. Support for IANA registration of ...
GnuTLS (/ ˈ ɡ n uː ˌ t iː ˌ ɛ l ˈ ɛ s /, the GNU Transport Layer Security Library) is a free software implementation of the TLS, SSL and DTLS protocols. It offers an application programming interface (API) for applications to enable secure communication over the network transport layer, as well as interfaces to access X.509, PKCS #12, OpenPGP and other structures.
mbed TLS (previously PolarSSL) since version 1.3.6 released in April 2014 [7] s2n since its original public release in June 2015. wolfSSL (formerly CyaSSL) since version 3.7.0 released in October 2015 [8] Go (in the standard library crypto/tls package) since version 1.4 released in December 2014 [9]
Internet Explorer 11 added support for SPDY version 3, [49] [50] but not for the Windows 7 version. [51] A problem experienced by some users of Windows 8.1 and Internet Explorer 11 is that on initial loading, Google says "Page not found" but on reloading, it is fine. One fix for this is to disable SPDY/3 in Internet Options > Advanced. [52]
A downgrade attack, also called a bidding-down attack, [1] or version rollback attack, is a form of cryptographic attack on a computer system or communications protocol that makes it abandon a high-quality mode of operation (e.g. an encrypted connection) in favor of an older, lower-quality mode of operation (e.g. cleartext) that is typically provided for backward compatibility with older ...
The Working Group presented HTTP/2 to the Internet Engineering Steering Group (IESG) for consideration as a Proposed Standard in December 2014, [6] [7] and IESG approved it to publish as Proposed Standard on February 17, 2015 (and was updated in February 2020 in regard to TLS 1.3 and again in June 2022). The initial HTTP/2 specification was ...
