P4 XAdES-X LONG (Type 1)
General Information
Long-term and OCSP-based Secure Electronic Signature Policies (Profile P4) is defined by Information and Communication Technologies Authority (ICTA) in Electronic Signature Usage Profiles which is a guide of signature profiles for Turkey. In this profile, long term compatibility is provided with ES-X LONG and ES-A signature formats. In addition, this profile requires the use of OCSP for end-user certification revocation control. These requirements are provided by the XAdES-X LONG Type 1 signature format in accordance with the P4 profile.
The ES-X LONG Type 1 (Extended Long Electronic Signature with Time Type 1) signature is based on the ES-T signature. In addition to ES-T signature, it includes the root and sub-root certificates of the certification authority and the CRL and OCSP responses for signature verification. This enables the signature to be validated for a long period of time.
This data, which is added to the signature file, is used while performing signature verification. It does not need to connect to any external system for signature verification and to obtain verification data; all data required for verification is accessed from the contents of the signature file. It is the most recommended signature format thanks to these features.
The following table specifies the signature properties that must be included in the signature file for P4 XAdES-X LONG signature format:
