Securing electronic health records with broadcast encryption schemes.

Area of Science:

• Computer Science
• Information Security
• Healthcare Informatics

Background:

• Integrated electronic health record (EHR) systems face significant information security challenges.
• Protecting sensitive patient data within EHRs is crucial for maintaining trust and compliance.
• Existing security models may lead to complex data management and inefficient access control.

Purpose of the Study:

• To develop a novel mathematical model for enhancing information security in integrated EHR systems.
• To address the open problem of secure and efficient access to EHR data.
• To minimize the overhead associated with securing EHR data for multiple users.

Main Methods:

• Development of a mathematical model based on broadcast encryption principles.
• Incorporation of broadcast encryption schemes to manage EHR access.
• Design of a solution that generates fewer encrypted ciphertexts compared to traditional methods.

Main Results:

• The proposed solution significantly reduces the number of encrypted ciphertexts required for secure EHR access.
• Achieved shorter ciphertext lengths compared to systems encrypting data for each participant individually.
• Demonstrated practical applicability in securing EHR systems.

Conclusions:

• The developed mathematical model offers a practical and efficient approach to securing EHRs.
• The broadcast encryption-based solution enhances data security while optimizing ciphertext size.
• This work contributes to solving the critical challenge of information security in modern healthcare IT infrastructure.
