[RFC 0/1] ima/evm: signature verification support using asymmetric keys

2013-01-15 Thread Dmitry Kasatkin
Asymmetric keys were introduced in linux-3.7 to verify the signature on signed kernel modules. The asymmetric keys infrastructure abstracts the signature verification from the crypto details. This patch adds IMA/EVM signature verification using asymmetric keys. Support for additional signature v
