What is CycurLIB
Cryptographic protocols and algorithms are the fundamental foundation of security functionality in most IT security applications. For example, cryptographic algorithms such as digital signature verification are required to protect flash solutions, enable features, or secure boot.
ESCRYPT's CycurLIB provides the perfect cryptographic library for these needs. Optimized for embedded systems, CycurLIB has a long standing reputation for outstanding performance in resource-constrained environments.
Product Summary
CycurLIB offers a simple way to make your products even more reliable. Examples include verifying digital signatures to determine data authenticity and encrypting data to ensure confidentiality. In addition, ESCRYPT's encryption library for embedded systems can be highly reconfigured according to customer needs, and various encryption algorithms can be safely and easily incorporated into ECUs, HMIs, PLCs, and various other devices. I can do it.
