Common use of Setup Phase Clause in Contracts

Setup Phase. In this phase, any user Ui has its identity IDi, and pub- lic key (x, TSi (x)) and a secret key Si based on Cheby- shev chaotic maps, a chaotic maps-based one-way hash function h(·) [35], and a pair of secure symmetric encryp- tion/decryption functions EK()/DK() with key K. The concrete notation used hereafter is shown in Table 1.
