An increasing number of cloud services, such as Amazon, Yahoo!, Google Drive, Dropbox, and iCloud, provides efficient and scalable data storage services at a considerably lower marginal cost than providers employing traditional ap-proaches. Uses of this type of storage include online data backup, photo sharing, and applications related to email and crucial documents. However, data stored in a cloud are vulnerable to loss, corruption through hardware and software fail-ures, and human errors. Thus, verifying the authenticity of data has emerged as a critical concern regarding data storage on cloud servers. To address the vulnerabilities of cloud-stored data, many approaches have been proposed. However, most of these approaches focus only on the data of indi-vidual users. This study addressed the data of groups and focused on categories that are generally considered crucial: testaments, vital contracts between organizations, and contracts between countries. Thus, to improve the security of cloud-stored group data, a verification protocol for group users based on the short signature protocol developed by Zhang et al. and the authenticated group key agreement protocol developed by Tsai is proposed.
