Repeatable dual-encryption platforms, coupled with a strong protective capacity for stored information, are highly desirable for current data security but still a challenge to be realized. Herein, a new type of thermoset-based repeatable dual-encryption platform is designed to fulfill the challenge. Through introducing dynamic boroxine bonds and hydrogen bonds within the thermoset, self-healing, recyclability, and shape-memory properties can be achieved. Given the shape memory behavior of this thermoset, encryption data within complex 3D structures can be realized. Thus, shape recovery is inevitable for the decryption, providing strong protection for encrypted data. Furthermore, the encrypted data can be protected by showing misleading information before true information during the decryption process, which is caused by the different analogous “LEGO” assembly sequences of thermosets that induces different hydrophobic association interactions. The decrypted information can be erased by heating, realizing the repeatable encryption/decryption. Additionally, the thermosets can be efficiently recycled. This strategy opens up a smart prospect for high level dual-encryption platform.

具有自愈能力和形状记忆效应的可回收热固性塑料的可重复双加密平台

可重复的双重加密平台，加上对存储信息的强大保护能力，对于当前的数据安全来说是非常可取的，但仍然是一个有待实现的挑战。为此，设计了一种新型的基于热固性的可重复双加密平台来应对这一挑战。通过在热固性材料中引入动态环硼氧烷键和氢键，可以实现自修复、可回收和形状记忆特性。鉴于这种热固性塑料的形状记忆行为，可以实现复杂 3D 结构内的加密数据。因此，形状恢复对于解密来说是不可避免的，为加密数据提供了强有力的保护。此外，可以通过在解密过程中在真实信息之前显示误导性信息来保护加密数据，这是由诱导不同疏水缔合相互作用的热固性材料的不同类似“乐高”组装序列引起的。解密后的信息可以通过加热擦除，实现可重复的加解密。此外，热固性塑料可以有效地回收利用。该策略为高级双加密平台开辟了智能前景。
