National Public Key Infrastructure Project


Public Key Infrastructure (PKI) technologies form the basis of electronic identity card, electronic signature and e-government applications. The Electronic Certificate Management Infrastructure (ESYA) developed within the scope of the MA3 Project is the only national software in Turkey that generates and manages electronic certificates, which form the heart of AAA technologies, and is one of the few products in the world with Common Criteria (CC) EAL4+ certification in this field.
ESYA software is used by KamuSM Certificate service provider, which is authorized to issue certificates to public institutions in Turkey. The production and management of the certificates to be produced within the scope of the Republic of Turkey Identity Card Project and the e-Passport Project are carried out with ESYA software. Also, Timestamp Server and Timestamp Client are our other widely used applications.
Kermen PKI Client is a family of client applications that provide desktop security services.
MA3 API is to create the infrastructure of projects such as e-Signature and Encryption Libraries, e-Correspondence, e-Government, UYAP, e-Ledger, e-Invoice, e-Prescription. Software companies, telecommunications companies, banks, universities and public institutions have developed and are developing hundreds of e-Signature products using the MA3 API. Software support continues to be provided to these institutions.
Our ESYA, KERMEN and MA3 API products are widely used in many private and public institutions, especially in the Turkish Armed Forces. Our products are updated according to changing and developing technologies and standards (ETSI, RFC and ISO etc.) and new features are added to the products in line with the needs.

MILSEC 4 - Secure IP Terminal


While the MİLSEC-4 terminal offers an up-to-date solution for next-generation secure communication (voice, data and video) in IP networks, it provides an uninterrupted communication service by maintaining the compatibility of secure voice communication in PSTN networks with PSTN secure phones in use.

Configuration, surveillance and software update processes of MILSEC-4 terminals are carried out securely remotely using the Security Management Center (GYM). MİLSEC-4 terminal is capable of IP Network Key Loading (IPAAY) through secure communication with GYM without the need for an additional device.

MİLSEC-4 terminals are interoperable with MİLSEC-1A and MİLSEC-2 phones and offer the opportunity to replace MİLSEC-1A and MİLSEC-2 phones without interruption in the gradual transformation of PSTN networks to next generation IP networks.
