A71CL

Plug & Trust Secure Element

Features and benefits

3.1 Key benefits

 Secure, zero-touch connectivity

 End-to-end security, from chip to edge to cloud

 Secure credential injection for IC-level root of trust

 Fast design-in with complete product support package

 Easy to integrate with different MCU platforms

3.2 Security features

The A71CL security concepts includes many security measures to protect the chip.

The A71CL operates fully autonomously based on an integrated Javacard operating

system and applet. Direct memory access is possible by the fixed functionalities of the

applet only. With that, the content from the memory is fully isolated from the host system.

Attack protection by integrated design measures in the chip layout, the logic and the

functional blocks.

3.3 Cryptography features

 Message digest with SHA1, SHA224, SHA256

 Random number generator

 Asymmetric key storage type: RSA Standard or RSA CRT

 Auto RSA key generator ranges from 512-bit key length to 2048-bit key length. Either

RSA Standard or RSA CRT.

 Symmetric encryption/decryption with DES_CBC_NOPADDING,

DES_ECB_NOPADDING, AES_CBC_NOPADDING, AES_ECB_NOPADDING.

 Symmetric signature/verification with DES_CBC_ISO9797_M1,

DES_CBC_ISO9797_M2, AES_CBC_ISO9797_M1, AES_CBC_ISO9797_M2.

 Asymmetric encryption/decryption with RSA_NOPADDING, RSA_ PKCS1.

 Asymmetric signature/verification with RSA_SHA1(PKCS1), RSA_SHA256.

 Service data storage: the storage data read and write is protected by SCP.

 SCP 02 service with option “i” = ‘55’.
