LEADTOOLS DICOM Security supports the Secure Transport Connection Profiles as specified in part 15 of the DICOM 2003 standard. Included in this add-on is support for TLS secure transport connection profile and ISCL Secure transport connection profile. The LEADTOOLS DICOM Security support eliminates the need of a VPN (virtual private network) for secure communication to comply with HIPAA regulations.
Use LEADTOOLS DICOM Security to encrypt sensitive data between DICOM nodes that you develop, or existing nodes that support TLS or ISCL connection profiles.
HIPAA Privacy and Security required compliance by April 14, 2003 with standards for guarding data integrity, confidentiality and availability for any application that maintains or transmits individual health data. LEADTOOLS DICOM Security allows for quick, accurate, and complete implementation of security functions that will ensure an application connected to the Internet will be HIPAA compliant. Three areas of risk as well as computer/entity authentication, confidentiality and data integrity are addressed with the LEADTOOLS DICOM Security for efficient 128-bit encryption implementation.
| Area at Risk | LEADTOOLS Medical Security Solution |
|---|---|
| Computer/Entity Authentication | RSA Based Certificates |
| Confidentiality | DES Encryption & 3DES Encryption |
| Data Integrity | Secure Hash Algorithm Ciphersuite Negotiation |
| MORE ABOUT TLS |
| Area at Risk | LEADTOOLS Medical Security Solution |
|---|---|
| Computer/Entity Authentication | Three-pass-four-way Protocol |
| Confidentiality | DES-CBC Encryption. This is a 56 bit effective key length in a 64 bit key encryption cipher in block chaining mode. |
| Data Integrity | DESMAC (64 bit) and DES-encrypted MD5 (128 bit) message authentication codes. |
