Recently, many searchable public-key encryption (SPE) schemes have been designed to balance security and efficiency. However, these SPE schemes face the challenge of certificate management or key escrow. This is because they are constructed based on public key infrastructure (PKI) or identity (ID)...
Property owners would be forced to place the keys to their businesses in boxes outside their doors so that firefighters, in that one-in-a-million chance, would have easy access to get inside.We in the computer security world have been here before, over ten years ago.Tags: fire, key esc...
The only thing that’s bothersome to me about the Cedar Falls version is that I believe they included apartment buildings in their code. That’s a little unusual, and it’s not clear if the individual units are required to escrow their keys, or if it only covers the main entrances, etc...
In this article, we systematically survey recent trending technologies from an IoT security point of view and discuss traditional key security mechanisms. This article delivers a comprehensive quality study for researchers on authentication and session keys, integrating IoT with blockchain and AI-based a...
The scheme [7] has the key escrow problem. The scheme [11] is vulnerable to some well-known attacks and has extra overhead for PKI maintenance. In addition to these issues, some factors are also important including the monitoring of the number of smart electrical equipment in the needs of...
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...
proposed an anonymous ECC-based self-certified key distribution scheme [25], the scheme is not only free from the overhead of the certificate management and the key escrow issue, but is also more efficient than anonymous schemes in terms of both communication and computational costs. In 2020, ...
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 ...
