SHA Secure Hash Algorithms. The SHA is one of a number of
cryptographic hash functions. A cryptographic hash is like a
signature for a text or a data file. SHA-256 algorithm generates
an almost-unique, fixed size 256-bit (32-byte) hash. Hash is a
one way function – it cannot be decrypted back.
SMT
Signal matrix tool within PCM600
SNTP Simple network time protocol – is used to synchronize
computer clocks on local area networks. This reduces the
requirement to have accurate hardware clocks in every
embedded system in a network. Each embedded node can
instead synchronize with a remote clock, providing the required
accuracy.

SSL/TLS Transport Layer Security (TLS) and its predecessor, Secure
Sockets Layer (SSL), are cryptographic protocols that provide
communication security over the Internet. TLS and SSL
