Classification: H04L

Abstract:
A method for providing portable cryptographic keys, comprising:creating an ASN.1 format for portable key information at a sender node;generating first platform-specific data structure definitions at the sender node;creating first platform-specific data values at the sender, representing portable key information based on the first platform-specific data structure definitions;encoding portable key information at the sender using first platform-specific ASN.1 encoding functions to create a platform independent ASN.1 encoded protocol data unit (PDU) corresponding to the portable key information;sending the platform independent ASN.1 encoded protocol data unit (PDU) to a receiver node;creating said ASN.1 format for portable key information at the receiver node;generating second platform-specific data structure definitions at the receiver node; anddecoding the platform independent ASN.1 encoded protocol data unit (PDU) using second platform-specific ASN.1 decoding functions to obtain second platform-specific key information at the receiver node.
