    Secure Storage ? 
    Did you mean 'Protected' Storage, more in line with the MS lexicon ? 
    Then this is the task of PSTORES.EXE, not of LSASS.EXE
    
    The original LSASS.EXE is in fact the Local Security Administration
    Subsystem and it does a lot more. As the Local Security Authority component
    of the Windows NT Security Subsystem, it handles all aspects of security
    administration on the local computer, including access and permissions, and
    also works with the domain controllers for validation when and if needed. 
    
    To quote Microsoft : (see
    http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechn
    ol/winxppro/reskit/prdp_log_tota.asp) 
    
    
    Validation in Windows is performed by a protected subsystem called the Local
    Security Authority (LSA)
    </technet/prodtechnol/winxppro/reskit/gloss_rk_pro.asp?frame=true> , which
    maintains information about all aspects of local operating system security.
    In addition to providing interactive user authentication services, the LSA
    does the following:
    *	Manages local security policy. 
    *	Manages audit policy and settings. 
    *	Generates tokens that contain user and group information as well as
    information about the security permissions for the user.
    The LSA validates your identity based on which entity issued your account.
    If it was issued by:
    *	LSA. The LSA can validate your information by checking its own
    Security Accounts Manager (SAM) database. Any workstation or member server
    can store local user accounts and information about local groups. However,
    these accounts can only be used for accessing that workstation or computer. 
    *	Security authority for the local domain
    </technet/prodtechnol/winxppro/reskit/gloss_rk_pro.asp?frame=true>  or for a
    trusted domain. The LSA contacts the entity that issued your account and
    asks it to verify that the account is valid and that you are the account
    holder.
