Which two statements best describe enhanced wireless security encryption?
(Select two) A. CKIP protects RC4 encryption keys. B. WPA requires CKIP encryption, whereas WPA2 supports AES encryption. C. CKIP encryption is more processor intensive than AES encryption is. D. WPA requires AES encryption, whereas WPA2 supports CKIP encryption. E. CKIP and CKIP protect AES encryption keys. Answer: A, B Explanation: Temporal Key Integrity Protocol (CKIP) protects the WEP key from exploits that seek to derive the key using packet comparison. Message integrity check (MIC) is a mechanism for protecting the wireless system from inductive attacks, which seek to induce the system to send either key data or a predictable response that can be analyzed to derive the WEP key. CKIP and MIC are both elements of the WPA standard, which is intended to secure a system against all known WEP key vulnerabilities. Note that Cisco implemented a prestandard version of CKIP and MIC in late 2001, known as CKIP and CMIC, before WPA was available for customers. Current Cisco equipment support
