Secure identity access and data transmission scheme of cloud-assisted intelligent gymnasium

Addressing the privacy security challenges in identity access and data transmission for cloud-assisted intelligent gymnasium, this paper designs a secure identity access and data transmission scheme (SIA-DTS). SIA-DTS employs a three-factor authentication method to achieve secure authentication, protects the privacy of identities, utilizes elliptic curves for enhanced performance and security, and applies lightweight hash operations to minimize computational load. It also establishes secure session keys through Diffie-Hellman key exchange for data transmission security. SIA-DTS is proved to be secure and meets various security requirements as shown by the mode and informal analysis. Furthermore, performance analysis reveals that SIA-DTS significantly reduces computation and communication overhead, thereby improving operational efficiency. All relevant data are within the paper. • This paper proposes a secure identity access and encrypted data transmission scheme. • Through the security analysis, the scheme can effectively resist all kinds of attacks on the sensitive information. • Through performance and experimental verification, the scheme improves data security and user privacy protection.
