Abstract
Root certificates generated by root certificate authorities may be bound at the time of generation. In an example, a first root certificate can include an identity of a first root certificate authority, a first key identifier associated with a first key of the first root certificate authority and an identity of a first digital signature algorithm used by the first root certificate authority. The first root certificate can also include at least one extension including a second key identifier of a second key associated with the second root certificate authority and an identity of a second digital signature algorithm used by the second root certificate authority, the second digital signature algorithm being different from the first digital signature algorithm.
