It is a primitive mechanism that brings the limitations of PUF in IoT network security, which is irreplaceable [171]. Tan’s scheme is vulnerable to gateway node forgery attacks and escrow attacks. In the year 2021, Leandro and Westphall [115] introduced a multi-factor peer authentication ...
Far from hypothetical or academic, this escrow scheme provides an easy opportunity for corporate spies or saboteurs to bypass all static, physical defenses in an organization. One key to enter them all is much better for the attacker than beating each location’s individual security configuration. ...
Having the security guard walk around the building all-thought cover less area, and have no tracking device on them, the thefts would have to hack physic which should be alot harder than computers, and delete or editing someone mind is less reliable than digital means(say a lighting stick re...
Key escrow issueBlockchainWith the continuous advancement of digital healthcare, the application of Internet of Things and cloud storage technologies has enabled the sharing of personal health data, thereby simplifying patient care and improving operational efficiency. However, sharing medical data through...
Many organizations will use a key escrow to protect and easily recover cryptographic keys in case of an emergency, like a security breach or natural disaster. The private keys are stored in a trusted third party and the organization can set guidelines for the escrow service provider on who is...
To solve these challenges, we propose a lightweight authentication and key agreement protocol for smart grid which is free from key escrow issues and provides more security and privacy features. We provide a formal security analysis of the proposed scheme which is based on the random oracle model...
To solve the key escrow problem in IBEKS, Peng et al. [18] proposed the first searchable encryption scheme based on certificateless public key cryptography [19]. However, Peng et al.’s scheme are vulnerable to both outside and inside KGA. Therefore, some certificates PAEKS (CLPAEKS) sche...

The security team identifies aninsider threat. If necessary, reactivating a revoked key can help admins decrypt data previously encrypted with it, like old backups. Backup (or Escrow) All keys require a backup before deactivation, so the manager should keep a mirror archive of all deactivated ...
Performing necessary key functions such as key generation, pre-activation, activation, expiration, post-activation, escrow, and destruction. Securing physical and virtual access to the key servers. Limiting user/role access to the encryption keys. ...
