The State of Illinois (SOI) Public Key Infrastructure (PKI) provides authentication, encryption, and digital signature services to over twenty State Agencies, and over thirty local government and educational entitles including the City of Chicago Department of Public Health, Kane County Circuit Clerk's office, and Southern Illinois University In Carbondale. The State of Illinois' PKI program is instrumental in providing a more secure IT infrastructure necessary to operate in an increasingly hazardous web environment. The PKI system allows the SOI to certify SOI web based applications; provide digital IDs to application users in all fifty states and in some foreign countries as well; allows SOI employees to digitally sign documents; and allows SOI employees to send secure emails over the web. Not having a PKI program would severely degrade the SOI's cyber security posture. By utilizing a centralized environment for these services, the State has saved tens of thousands of dollars in duplicated efforts. With tougher security standards in place, more stringent laws regarding data breaches, and sensitive data being transmitted with increasing frequency, PKI provides the ability to meet standards and protect both data and identities.
