EaseFilter File System Encryption Filter Driver SDK について


EaseFilter File System Encryption Ffilter Ddriver SDK provides a comprehensive solution for transparent file level encryption. It allows developers to create transparent encryption products which can encrypt or decrypt files on-the-fly, it can allow only authorized users or processes to access the encrypted files. Supported strong cryptographic algorithm Rijndael is a high security algorithm which was chosen by the National Institute of Standards and Technology (NIST) as the new Advanced Encryption Standard (AES), it can support key lengths 128-bits,192-bits and 256-bits.

EaseFilter File System Filter Driver SDK Solutions

A file system filter driver intercepts requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request.To develop file systems and file system filter drivers, use the Windows Driver Kit (WDK),which is provided by Microsoft. Even with the resources available in the Windows Driver Kit (WDK) developing file systems is certainly a challenge. To simplify your development and to provide you with a robust and well-tested file system filter driver that works with all versions and patch releases of the Windows operating systems supported by Microsoft, EaseFilter Inc. offers the file system filter driver SDK which provides a complete, modular environment for building active file system filters in your application.

EaseFilter File System Encryption Filter Driver SDK

EaseFilter File System Encryption Filter Driver SDK provides reliable protection for data leakage by using transparent file encryption technologies. The processes of encryption and decryption are executed in file system filter driver and are completely transparent to users. By leveraging this transparent approach, your organization can implement encryption, without having to make changes to your applications, infrastructure, or business practices.

Transparent File Encryption and Decryption

Transparent file encryption (TFE) performs real-time I/O encryption and decryption of the files in any block data with 16 bytes. The encryption uses a 256 bits symmetric key to encrypt or decrypt the data with AES encryption algorithm. TFE protects data "at rest", meaning the data and files. It provides the ability to comply with policies which can be applied by users, processes and file type. This allows only authorized users and processes to access the encrypted files, unauthorized users and processes can’t access the encrypted files.
