DecryptNaBox for the Enterprise eliminates the need for private key escrow during data decryption by separating the decryption process into two different functions. The Data Decryption function is responsible for data decryption using a decrypted message session key. The Session Key Decryption function handles the decryption of the message session key to be used by the Data Decryption function. Architected with this separation of Session Key and Data Decryption functions, the need for a local copy of the user's private key to perform data decryption is eliminated.

At a high level, DecryptNaBox for the Enterprise is a Client/Server platform where both the Client and Server consist of multiple services and adapters. The server is referred to as Zeva KeyDecrypt which extends associated Certificate Authorities with Message Session Key Decryption (MSKDS) capabilities. In addition, KeyDecrypt server includes the use of a Hardware Security Module (HSM) to ensure secure key handling and compliance with FIPS 140 Level 2 and Level 3 requirements.

Zeva KeyDecrypt Server

The KeyDecrypt Server is responsible for retrieving keys from a CA and decrypting message session keys. By utilizing the KeyDecrypt server, the need to manually retrieve private keys for data decryption is eliminated. In addition, KeyDecrypt server provides the highest level of private key protection and safe handling. This is accomplished through the use of encrypted channels for all queries and transport, and Hardware Security Module (HSM) technology for private key handling.

The KeyDecrypt server also provides a solid approach for ensuring that system audit logs and configuration files are protected via the audit and configuration trust protection feature. In addition to guaranteeing protection, it also ensures that the integrity of the audit logs can be verified.

To help address different customers need, Zeva Inc. provides two editions for the KeyDecrypt: Government and Commercial. The Government Edition is designed for the US federal government agencies. It includes all required components and the Commercial Edition is designed for common commercial usage. It provides an affordable entry point with optional features to increase system security to comply with applicable regulatory and security requirements.

Veritas Enterprise Vault Filter

As part of our dedication to the platform, Zeva offers Enterprise Vault customer with an extension filter to process encrypted data within Enterprise Vault engine itself.

MobileDecrypt

MobileDecrypt is a special client allows users to read encrypted email messages on mobile devices without direct access to smart card credentials or user private keys.The use of smart card PKI credentialing with encrypted electronic mail poses significant challenges for the mobile device users. Encrypted messages remain encrypted on the mobile device until smart card credentials are made available to the device, or unless the user’s private key is stored on the mobile device. For smart card credentials to be available to the mobile device a smart card reader is required. The storage of private keys on mobile devices poses a serious security risk, and is a violation of most organizations’ encryption key policies. Zeva MobileDecrypt solves this challenge by allowing the mobile device user to decrypt email messages without the need to use smart card credentials.
