WebTLS 1.3 supports Pre-Shared Key (PSK) authentication, wherein PSKs can be established via session tickets from prior connections or via some external, out-of-band mechanism. The … WebFeb 20, 2024 · External PSK authentication in TLS allows endpoints to authenticate connections using previously established keys. These keys do not provide protection of endpoint identities (see Section 5 ), nor do they provide non-repudiation (one endpoint in a connection can deny the conversation).
WebJan 6, 2024 · There are three main suites in TLS-PSK. The first, PSK, uses this shared-secret directly to derive all symmetric key material for the protocol. The latter two, RSA_PSK and … WebIn this table, the values are computed using the smallest allowed hash function (SHA-256) and curve (X25519). As can be seen, a rTLS PSK requires only roughly 11 % of the traffic overhead compared to a standard TLS PSK and can be expected to reduce the total amount of transmitted data roughly by half.
WebIn this table, the values are computed using the smallest allowed hash function (SHA-256) and curve (X25519).

These pre-shared keys are symmetric keys shared in advance among the communicating parties.
WebTLS-PSK is only a good choice where means exist to securely share a key with every connecting machine, so it does not replace the public key infrastructure (PKI) for the majority of TLS uses. The TLS-PSK implementation in OpenSSL has seen many security flaws in recent years, mostly because it is used only by a minority of applications. ...
