A new protocol for digital mobile communications is proposed. This protocol permits users to hold a secure conference and ensures public safety. The traditional symmetric key encryption algorithm was improved to achieve end-to-end security and non-repudiation for each individual communication connection. Different from public-key encryption algorithm, non-repudiation of the proposed symmetric key encryption algorithm is arbitrated once the communication is disputed or doubted to endanger public safety.
