Method and apparatus for applying execution context criteria for execution context sharing

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more computer programs,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• retrieve an execution context;
• determine one or more context criteria associated with the execution context, wherein the context criteria include state information associated with the execution context;
• and
• encrypt the execution context using the one or more context criteria as a public key of an identity-based encryption.

A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

• retrieving an execution context;
• determining one or more context criteria associated with the execution context, wherein the context criteria include state information associated with the execution context;
• and
• encrypting the execution context using the one or more context criteria as a public key of an identity-based encryption.
