Abstract — Internet of Things (IoT) and Cloud Computing paradigm paradigm is a next wave in the era of computing computing and it has been identi identifie fied d as one of the emerging emerging tech technol nologi ogies es in the field of Compute Computerr Scienc Sciencee and Inform Informati ation on Tech echnol nology ogy.. It has been understood from the review reports that integration of IoT and Cloud Computing is in its infantile phase and it has not been extended to all application domains due to its inadeuate security architecture. !ence" this paper builds an integrated" secured and intell intellige igent nt archit architect ectur uree for the IoT and Cloud Cloud Comput Computing ing is envis envisag aged ed to offe offerr secur securee smar smartt servi service cess and and appl applic icat atio ions ns anywher anywhere" e" anytim anytime" e" any firm" firm" any device and any networ# networ# independent of any underlying technologies with one IoT enabled $cute $cute Smar Smartt Card Card ($SC ($SC). ). $SC ease easess the the secur securee acces accesss of divers diversifi ified ed applic applicati ations ons and service servicess distri distribut buted ed in a cloud cloud environment with one Special Identification (SI%) number per citi&en through the intelligent systems and also 'tili&e  uniuely combine *+$,- (ey *olicy $ttribute+,ased -ncryption)" la&y re+encryption to achieve Scalable" ine+/rained access control on out sourced data in the cloud.
