Electronic patient records (EPR) may contain highly confidential and sensitive medical data, and it is therefore essential that such information is properly protected. Medical teams that are providing care to a patient has a legitimate need to access the medical dataof the concerning patient, and this could be a valid criteria for medical professionals to obtain access to such data. Moreover, since teams consist of more than one individual, the consent or agreement among a number of the members of a medical team could by itself be a proper basis for trust and therefore a legitimate basis for medical teams to acquire access to medical data.In this paper, we present three closely related cryptographic protocols for secure team-based EPR access acquisition where the cryptographically verifiable mutual consent from some minimum number of participants of a medical team is the granting criteria for the team to acquire EPR access. The schemes are based on thresholdcryptography and are moreover broadcast-oriented, and are thus well-suitable for wireless networks. All schemes do also provide secure transfer of medical data.
