emCA for Electronic Passport (ePassport) PKI

ePassports are electronic passports that contain an RFID chip embedded within the pages of the passport. This chip stores the passport holder's biographical data, photo, and digital signature. ePassports are more secure than traditional passports because they are more difficult to counterfeit or tamper with.

Role of eMudhra emCA in ePassport PKI

emCA solution that can be used to manage the digital certificates used in ePassports. It can be used to issue, renew, and revoke digital certificates, as well as to manage the Certificate Revocation List (CRL).

Benefits of Using emCA for ePassport PKI

There are a number of benefits to using eMudhra emCA for ePassport PKI, including:

  • One-stop-shop: All the necessary PKI components that are required for setting up of ePassport PKI is available with eMudhra.

  • Security: provides robust security features to protect ePassport digital certificates from unauthorized access and use.

  • Scalability: highly scalable solution that can be used to manage ePassport digital certificates for countries of all sizes.

  • Ease of use: user-friendly solution that simplifies the process of managing ePassport digital certificates.

  • Compliance: helps countries comply with international standards for ePassport PKI.

Basic Access Control (BAC)

Basic Access Control (BAC) is a security mechanism that allows authorized readers to access basic data stored on the RFID chip of an ePassport, such as the passport holder's name, date of birth, and passport number.

To implement BAC, each country must establish a Country Signing Certificate Authority (CSCA). The CSCA issues digital certificates to Document Signers, which are responsible for signing the data stored on the ePassport RFID chip.

emCA can be used to set up and manage the CSCA and Document Signers. It can also be used to issue digital certificates required for master list signing, deviation list signing etc.

Extended Access Control (EAC)

Extended Access Control (EAC) is a security mechanism that allows authorized readers to access biometric data stored on the RFID chip of an ePassport, such as fingerprints and iris scans.

To implement EAC, each country must establish a Card Verifiable Certificate (CVC) Certificate Authority (CA). The CVC CA issues digital certificates to Document Verifier CAs (DVCAs), which are responsible for signing the data stored on the ePassport RFID chip.

emCA can be used to set up and manage the CVCA and DVCAs. It can also be used to issue digital certificates through CVC CA and DVCAs such as Terminal certificates.

emCA suite can be used to implement both Basic Access Control (BAC) and Extended Access Control (EAC) in ePassports. By using emCA, countries can ensure that their ePassports are secure and that the data stored on the ePassport RFID chip is protected from unauthorized access.

Industrial IoT Security:

eMudhra's emCA offers a cutting-edge Public Key Infrastructure (PKI) framework tailored to empower enterprises in establishing a secure and robust Internet of Things (IoT) ecosystem.

To meet these challenges, IoT solutions must prioritize the fundamental tenets of information security—confidentiality, non-repudiation, and integrity. This can be effectively achieved through the implementation of Public Key Infrastructure (PKI). Digital Signature Technology, operating within the PKI framework, employs a Cryptographic Key Pair—Private and Public Key—for secure access and transmission of information. These robust encryption algorithms play a pivotal role in handling large volumes of data and mitigating the risks associated with unauthorized access to sensitive information.

Business Matters: The 2017 IoT developer survey conducted by the Eclipse IoT Working Group underscores security as the foremost concern for IoT developers. The vast array of physically connected devices in IoT has become an enticing target for hackers and cybercriminals. A comprehensive solution is imperative to ensure data confidentiality, information integrity, authentication, and precise data access control.

Business Need: In the realm of emerging technologies, the challenge lies in ensuring the provision of trustworthy information from connected devices to users or platforms. There is an inherent need for high-integrity messaging, secure communications, and robust authentication at scale.

Approach: IoT demands two primary security requisites: trust and control. Implementing these on a large scale for IoT introduces new challenges, necessitating a reevaluation of traditional assumptions about key management and impending security threats. PKI technologies, proven in large-scale systems like global payment systems, provide a foundational framework, albeit with considerations for the unique challenges posed by IoT.

Digital Signature and Encryption Technology: Digital Signature Technology, operating within the PKI framework, leverages a Cryptographic Key Pair Private and Public Key for secure access and transmission of information. The adoption of efficient and unbreakable encryption algorithms is crucial for handling voluminous data and mitigating the risks associated with unauthorized access to sensitive information.

Solution: PKI, anchored in the use of Digital Certificates, has been the linchpin of internet security. emCA, with extensive experience across various industries, specializes in issuing Digital Certificates using diverse signature algorithms, public key sizes, standards, and cryptographic properties to meet specific needs. eMudhra's expertise extends to providing specialized IoT security solutions.
