In today’s interconnected world, the line that separates the network perimeter can no longer be identified. This has led to the development of Zero Trust Networking (ZTN) and Software Defined Perimeter (SDP) concepts, which aim to extend the perimeter of trust to every entity connected to the network regardless of their physical location. However, implementing complex security mechanisms and constant trust assurance for every interaction can be challenging. One solution is integrating blockchain technology into Zero Trust to provide security. Blockchain offers features such as data decentralization, anonymity, cryptography, and immutable record of transactions that can be utilized. This work proposes a mechanism for secure service session management using blockchain capabilities. Non-fungible tokens (NFT) are applied to access and provider tokens representing a policy agreement for service consumption. These tokens are mapped to the public addresses of entities registered in the blockchain. The proposal is realized through an open-source Zero Trust platform and a private Ethereum blockchain.

在当今互联的世界中，分隔网络边界的线不再能够被识别。这导致了零信任网络 (ZTN) 和软件定义边界 (SDP) 概念的发展，这些概念旨在将信任边界扩展到连接到网络的每个实体，无论其物理位置如何。然而，为每次交互实施复杂的安全机制和持续的信任保证可能具有挑战性。一种解决方案是将区块链技术集成到零信任中以提供安全性。区块链提供了数据去中心化、匿名、密码学和可利用的不可变交易记录等功能。这项工作提出了一种使用区块链功能进行安全服务会话管理的机制。不可替代代币（NFT）应用于代表服务消费策略协议的访问代币和提供商代币。这些代币被映射到区块链中注册的实体的公共地址。该提案是通过开源零信任平台和私有以太坊区块链实现的。
