Supported Encryption Modes
Baffle supports multiple database and file encryption modes including NIST certified and FIPS validated AES modes.
Baffle Encryption and Data Protection Modes
Baffle uses NIST approved cryptographic AES algorithms for the supported encryption modes. For FPE, Baffle uses NIST approved FF1 and FF3-1 algorithms. The cryptographic implementations use a FIPS 140-2 validated cryptographic module.
| Supported Data Protection Modes | Description |
|---|---|
| Field Level Encryption (FLE/ALE) | Table or column-based encryption using randomized, deterministic AES-CTR encryption or FPE |
| Record Level Encryption (RLE) | Support for row by row encryption using different keys mapped to entities for multi-tenant or shared databases. Uses randomized, deterministic AESCTR encryption or FPE |
| Secure Data Tokenization (TOK) | Uses deterministic AES encryption to generate a deterministic encrypted transform for a given value. Can be applied to support JOINs and foreign key constraints to preserve referential integrity. Does NOT use code book method |
| Format Preserving Encryption (FPE) | Supports encryption where the cipher text output has the same form of the input. Preserves length of the data type. Can be applied to support JOINs and foreign key constraints to preserve referential integrity. Does NOT use code book method. Cannot be used in conjunction with RLE or Advanced Encryption. Baffle uses NIST approved FF1 and FF3-1 algorithms for FPE |
| File Object Encryption (DFP) | Supports encrypting data inside file objects for cloud data lakes, AWS S3 object storage, Azure blob storage. Encrypts semi-structured data to protect data inside objects in CSV or parquet formats. |
| Encryption Service API (API) | Baffle supports an encryption service API that enables support of virtually any application or data streaming method to perform encryption and decryption operations on data for the supported encryption modes. |
| Dynamic Data Masking (DDM) | Supports a library of masking formats that protects data at the presentation layer to prevent users from viewing data in the clear. Masking can be applied using static alphanumeric characters, randomly generated data values, and/or partially mask data values. Masking can be applied to both clear text and/or encrypted data |
| Role-based Access Control (RBAC) | Supports role or group-based policies in conjunction with data masking policies to restrict viewing of data based on group membership or other attribution. |
| Advanced Encryption (SMPC) | Support for privacy preserving analytics and secure data sharing on encrypted table or columnar data using randomized AES and secure multiparty compute (SMPC). This encryption mode facilitates operations and analytics on encrypted data across multiple parties without revealing data to other participating parties. |
