Abstract: A decentralized pseudonym scheme is proposed for providing storage, encryption and authentication of patients’ EHRs in cloud-based eHealth systems. The pseudonyms of a patient are generated from the patient’s secrets and each of them is used as the index of an EHR entry of the patient. An encryption key derived from the pseudonym can be used to encrypt the corresponding EHR entry. The pseudonyms can also be used for the patient proving the ownership of the EHR without disclosing the identity of the patient. Some protocols and remarks for using the pseudonym scheme are also discussed.
