  22. WAP Risks • WAP Gap • Claim: WTLS protects WAP as SSL protects HTTP • Problem: In the process of translating one protocol to another, information is decrypted and re-encrypted • Recall the WAP Architecture • Solution: Doing decryption/re-encryption in the same process on the WAP gateway • Wireless gateways as single point of failure
