TLS-PSK. Transport Layer Security pre-shared key ciphersuites ( TLS-PSK) is a set of cryptographic protocols that provide secure communication based on pre-shared keys (PSKs). These pre-shared keys are symmetric keys shared in advance among the communicating parties. There are several cipher suites: The first set of ciphersuites use only ...
The Legal Entity Identifier ( LEI) is a unique global identifier for legal entities participating in financial transactions. [1] Also known as an LEI code or LEI number, its purpose is to help identify legal entities on a globally accessible database.
