Bill, in this case the attacker, somehow manages to get a certificate authority to issue a false certificate binding Jane to the incorrect public key. Bill then becomes aware of the matching private key. Once John obtains and makes use of Jane’s public key in this phony certificate, the security of transactions between John and Jane could then be compromised by Bill. Bill just has to decrypt John’s messages or he could ruse John into accepting forged signatures from Jane.

To somehow counteract this, the certificate authorities make use of accreditation schemes to ensure that their standards are kept up to par. With regards to legally binding digital security certificates, local laws and regulations are put in place to make sure that even if the security is compromised, whoever is at fault will be prosecuted. Perhaps the best way for an online consumer to determine if a digital security certificate is indeed trustworthy is if that security certificate is issued by reputable certificate authority.
