3. REA INTERNAL USE ONLY © 2010 Renesas Electronics America Inc. All rights reserved. 3 Levels of security Software security BAD Memory chip security Almost as BAD Board ID SECURE Strong crypto Tamper proof PKI for Embedded Systems Avnet VAS Keys NOT protected CPU intensive (can be OK for PKI comp. by the host) (encryption alone is NOT security) Outdated key lengths (like a ‘ 2 digits ’ PIN code) We bring proven Web user authentication technology to Embedded Systems

4. REA INTERNAL USE ONLY © 2010 Renesas Electronics America Inc. All rights reserved. 4 Low Cost Security Solutions Maxim 1-wire Secure EEPROM – 1Kb – SHA-1 Atmel CryptoAuthentication – SHA-256, authentication only Atmel CryptoMemory – 1Kb to 256Kb – Proprietary 64bit symmetrical keys

5. REA INTERNAL USE ONLY © 2010 Renesas Electronics America Inc. All rights reserved. 5 Algorithms for Security SHA-1 / SHA-256 Simple message digest Not “true” encryption – Mostly used for digital signature signing SHA-1 retired from use by US government Symmetrical Cryptography Proprietary, DES, 3DES, AES – 64, 128, 256bit keys Symmetrical keys used on both sides – Keys must be handled with the highest security – Sharing of common keys can lead to compromise – Any key compromise affects every unit Asymmetrical Cryptography RSA, ECC 1024, 2048, 4096 bit keys Uses public / private key pairs – Private keys are all different – Compromise of a single key only affects a single unit Can be more complex to implement
