TLS

TLS

(1) See transparent LAN service.

(2) (Transport Layer Security) A security protocol from the IETF that is used to create an encrypted connection between the user's browser and a Web server. TLS also uses digital certificates to authenticate the server. For certain transactions, the client can be authenticated as well, but this is not necessary with normal browser interaction as public websites accept all visitors.

TLS is based on and supersedes Secure Sockets Layer 3.0 (SSL 3.0). Using stronger encryption algorithms than SSL, which has since been deprecated, TLS and SSL are not interoperable.

HTTPS Protocol and Port Number 465
A TLS session starts by sending a request to the Web server with an HTTPS prefix in the URL, which inserts TLS port number 465 into the packets. See well-known port and HTTPS.

The TLS client uses the public key to encrypt a random number and send it back to the server. The random number, combined with additional random numbers previously sent to each other, is used to generate a secret session key to encrypt the subsequent message exchange. See HMAC, digital certificate and EAP.


The Handshake
These steps take place to negotiate a TSL (or SSL) session before any user data are transmitted. The algorithm mentioned is the encryption method. In steps 5 and 6, the checksums ensure that the message was not tampered with (see MAC).

Since TLS is an acute emergency so early identification of high-risk patients, appropriate prophylactic interventions like hyper hydration, use of allopurinol, rasburicase and strict monitoring for its clinical complications like arrhythmia, AKI and central nervous system (CNS) manifestations in leukemic patients undergoing chemotherapy may help to decrease frequency, severity of TLS and improve outcome.2,4,5 There are number of local studies on various aspects of ALL but very few on incidences of TLS in children.
