An excellent introduction to the Pi Calculus is [P01], and the wiki page on the pi calculus[PiWiki] is worth visiting too.

The Pi Calculus has been introduced by Milner et al[MPW90]. An improved version of it optimized for cryptographic protocols, the Spi Calculus, has been proposed by Abadi and Gordon[AG99]. An interesting presentation of the pi calculus is in [ABF18]. The reason we care about the pi calculus is[B16], i.e. its use in ProVerif (and other verification tools).
