Electronic records are facing a profound crisis of trust, specifically manifested in issues such as tampering, damage, forgery, and information leakage. Single-set digital archiving system also requires the realization of trustworthy management of electronic records. To address the practical needs for trustworthy management of electronic records, based on the digital trust system, the connotation of trustworthy management of electronic archives is proposed, which includes trustworthy subjects, trustworthy activities, and trustworthy objects. The trustworthiness of subjects is characterized by dynamic and diverse subject trustworthiness, including verifiable identity, verifiable behavior, and sustained trust. The trustworthiness of activities is characterized by continuous and non-linear activity trustworthiness, including compliance of activities, continuous mutual trust throughout the entire process, and a secure execution environment. The trustworthiness of objects is characterized by the trustworthiness of dynamic and interrelated elements, including compliance of elements, security and consistency, and integrity and mutual trust. Based on the trustworthy elements, this paper discussed the technical strategies based on the new generation of trust technology, which includes identity authentication technology, formation technology, verification technology, monitoring technology, security technology, storage technology and so on. It also discussed the institutional strategies, which includes the regulation of subject rights and responsibilities, the regulation of the entire process management, and the regulation of element interrelation and mutual trust.
