Verification of serialization codes
First Claim
1. An apparatus, comprising:
- a processor; and
a memory device including computer program code, the memory device and the computer program code, with the processor, for causing the apparatus to perform at least the following;
provide modified serialization codes for a first entity in a serialization flow to replace existing serialization codes for the first entity in response to an indication that the existing serialization codes have been compromised to an untrusted entity,wherein the modified serialization codes have a representation of at least two different characters, andwherein a number of instances of one of the characters in the representation of the modified serialization codes is different from a number of instances of the one of the characters in the representation of the existing serialization codes;
receive serialization codes from a second entity, the second entity being downstream in the serialization flow from the first entity;
compare serialization codes from the second entity with the modified serialization codes; and
verify the serialization codes from the second entity by determining if the serialization codes from the second entity are compatible with the modified serialization codes.

Abstract
An example apparatus may include a processor and a memory device including computer program code. The memory device and the computer program code may, with the processor, cause the apparatus to provide modified serialization codes for a first entity in a serialization flow to replace existing serialization codes for the first entity. In various examples, the modified serialization codes may have a representation of at least two different characters, and a number of instances of one of the characters in the representation of the modified serialization codes may be different from a number of instances of the one of the characters in the representation of the existing serialization codes. The memory device and the computer program code may further cause the apparatus to receive serialization codes from a second entity, the second entity being downstream in the serialization flow from the first entity; compare serialization codes from the second entity with the modified serialization codes; and verify the serialization codes from the second entity by determining if the serialization codes from the second entity are compatible with the modified serialization codes.

7. A computer program product, embodied on a non-transitory computer-readable medium, comprising:
-
computer code for providing modified serialization codes for a first entity in a serialization flow to replace existing serialization codes for the first entity in response to an indication that the existing serialization codes have been compromised to an untrusted entity, wherein the modified serialization codes have a representation of at least two different characters, and wherein a number of instances of one of the characters in the representation of the modified serialization codes is different from a number of instances of the one of the characters in the representation of the existing serialization codes; computer code for comparing serialization codes from a second entity with the modified serialization codes, the second entity being downstream in the serialization flow from the first entity; and computer code for verifying the serialization codes from the second entity by determining if the serialization codes from the second entity are compatible with the modified serialization codes. - View Dependent Claims (8, 9, 10)
