Generating and processing an authentication certificate

A computer readable hardware storage device comprising instructions that when executed on a processor of a computer system performs a method for generating and processing an authenticity certificate, said method comprising:

• said processor receiving, from a requester entity, a request for a step certificate, said step certificate authenticating an involvement of the requester entity about an object, said request comprising, an object identifier, a requester entity type of the requester entity, and a requester identity certificate of the requester entity, wherein the object identifier identifies the object and is unique to the object;
• after said receiving the request, said processor hashing the object identifier;
• after said hashing the object identifier, said processor creating a signature comprising the hashed object identifier, the requester entity type, a certifier identity certificate of a certifier entity that has certified the authenticity of the object, and the requester identity certificate;
• said processor generating a hashing result by hashing a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature;
• said processor generating the step certificate comprising the hashing result;
• said processor encrypting the step certificate using a random key;
• and
• said processor sending the encrypted step certificate to the requester entity for subsequently storing the step certificate on a media.

A computer system comprising a processor, a memory coupled to the processor, and a computer readable storage device coupled to the processor, said storage device containing instructions which, upon being executed by the processor via the memory, implements a method for generating and processing an authenticity certificate, said method comprising:

• said processor receiving, from a requester entity, a request for a step certificate, said step certificate authenticating an involvement of the requester entity about an object, said request comprising, an object identifier, a requester entity type of the requester entity, and a requester identity certificate of the requester entity, wherein the object identifier identifies the object and is unique to the object;
• after said receiving the request, said processor hashing the object identifier;
• after said hashing the object identifier, said processor creating a signature comprising the hashed object identifier, the requester entity type, a certifier identity certificate of a certifier entity that has certified the authenticity of the object, and the requester identity certificate;
• said processor generating a hashing result by hashing a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature;
• said processor generating the step certificate comprising the hashing result;
• said processor encrypting the step certificate using a random key;
• and
• said processor sending the encrypted step certificate to the requester entity for subsequently storing the step certificate on a media.
