JaCarta PKI by Aladdin-RD is a solution for strict authentication and electronic signature using foreign cryptographic algorithms. JaCarta PKI USB tokens and smart cards have hardware implementations of cryptographic algorithms such as AES, DES, 3DES, RSA, and SHA, enabling strict two-factor user authentication and enhanced electronic signatures. JaCarta PKI supports Public Key Infrastructure (PKI), allowing its use in various information systems and electronic services. It ensures the integrity and confidentiality of transmitted data through encryption and message authentication. JaCarta PKI securely stores user data and key containers of popular cryptographic protection software in its proprietary secure non-volatile memory (EEPROM). It is compatible with over 150 domestic and foreign products and technologies, including Citrix, Microsoft CA, and Microsoft RDP. JaCarta PKI devices are available in various form factors, including USB tokens and smart cards, and are designed for intensive daily use with a familiar design and comfortable size. The devices feature a secure microcontroller that generates and stores the private key used for authentication, ensuring it never leaves the secure environment. JaCarta PKI devices are certified by the FSTEC of Russia, allowing their use in information systems up to class 1G security, state information systems up to class 1 security, and personal data information systems up to level 1 security. They are designed for long-term use, with a lifespan of at least 3 years and a data retention period in non-volatile memory of at least 10 years.
