SEFS transparent encryption cores is based on the latest MS IFS file system filter driver (MiniFilter ) Development of transparent encryption platform. Encryption logo embedded in the document itself can support PKCS7 electronic envelopes, encryption algorithm can be the core state. Also available at the application layer, the CSP to support MS standards, to be able to achieve encryption hardware TOKEN support. The encoding and decoding operations are subject to the protection of memory to complete, efficient security. No temporary files, the process of matching protective process to prevent the driver into memory Dump, and screen shots operation, full protect your confidential information. supporting the application layer control module can be controlled Shear panel, printing, etc. leak channels.

Technical Features

SEFS document as a pure IFS filter driver has the following characteristics :

• NEW: support for the application layer of encryption and decryption algorithms and hardware TOKEN. Support MS CSP andPKCS11standards。Application layer of encryption and decryption can be used as services or applications or COM exist. To meet the higher graded units of encryption hardware requirements. (The need to customize functions)
• Encryption logo placed in the document itself, extending the length of the document and content. PKCS7 figures can be realized envelope format file encryption package. Calmly embedded PKI system and to realize file permissions, identification, documents signed documents certifying similar MS EFS the function.
• Real-time encryption and decryption, transparent services. 。IFS is SEFS paper filter driver. The only authorized applications dense text to read when they needed declassified, read the number on the number of declassified. there will be no performance bottlenecks. But the physical hard disk is always kept secret text. The goals of any document on the physical hard drive to preserve and updated, and the Big Dipper will promptly SEFS encryption, the assurance was made on the physical drives of confidential state secret text. Of course, all this, SEFS the system is the kernel. Upper applications will increase because SEFS declassified change the application's behavior and habits.
• Users no choice mandatory encryption. SEFS mandatory encryption process of all classified operation of the document (including, but not limited to, temporary files, randomized, Export documents, etc.). No matter what type of Save the file name, Why-for-loaded kind of file formats (including unknown format), will be subject to strict encryption protection. Some even use file recovery tools can not be certain applications (such as Word) the explicit content.
• Strict checking process ciphertext. SEFS based on the application's characteristics and value checking names. Only authorized the decryption process can be completed so expressly. Illegal and camouflage the process will not be completed declassified. Only illegal process is via email or FTP and other network transmission will be encrypted.
• Perfect document cache control, even if authorized decryption process is running. Illegal process can not win ciphertext.
• SEFS2.0 MiniFilter use of the new structure, with a better antivirus software compatibility while the performance and stability, and the older IFS filter driver has obviously improved.
